Olfactory neuroblastoma is a rare cancer of the upper part of the nasal cavity called the cribiform plate, which is a bone deep in the skull between the eyes, and above the ethmoid sinuses. Copyright © 2014 Patrick L. Stevens et al. Olfactory Neuroblastoma 539 neoplasm filled the left palatine sinus and extended into the left maxillary sinus. This may be helpful in distinguishing it from other entities (see below) 3,7. J. Neurol. It grows in nerve tissue of babies and young children. In that case, opening pressure was not elevated. These patients can often be monitored closely for disease resolution without therapy [11]. Patrick L. Stevens, Douglas B. Johnson, Mary Ann Thompson, Vicki L. Keedy, Haydar A. Frangoul, Kristen M. Snyder, "Adult Neuroblastoma Complicated by Increased Intracranial Pressure: A Case Report and Review of the Literature", Case Reports in Oncological Medicine, vol. However, in the salvage setting, results have been unimpressive with complete response or partial response (CR/PR) occurring in only 19% of primary refractory disease and 52% of secondary refractory disease [15]. In addition, it carries a risk of long-term neurological sequelae [20]. This case represents the presentation of a common disease in an uncommon patient population. In the series by Rubie et al., only 20 (6%) of 316 patients with neuroblastomas had a primary tumor in the neck; none arose in a paranasal sinus. Lester D. R. Thompson. Surgery and radiation therapy may be sufficient for localized disease. Neuroblastoma can be identified using iodine-131-meta-iodobenzylguanidine (MIBG), which is an analog of noradrenaline because the adrenergic tissue absorbs this substance. Following MIBG therapy, she was able to discontinue all narcotics and became symptom free. There is bimodal age distribution with one peak in young adult patients (~2nd decade) and another peak in the 5th to 6thdecades. Despite medical therapy with acetazolamide and surgical placement of a VP shunt, her symptoms worsened, ultimately resulting in return of headaches and inability to see light from the left eye with minimal light appreciation in the right. Disease presentation is often similar in adults and children, though several differences have been described. A repeat bone marrow biopsy performed at our institution demonstrated extensive involvement by metastatic neuroblastoma (Figure 2). When an intracranial extension is present, peritumoural cysts between it and the overlying brain are often present. She commenced antineoplastic therapy with topotecan 1.2 mg/m²/dose and cyclophosphamide 400 mg/m²/dose on days 1–5. The patient was treated with systemic chemotherapy, I131 metaiodobenzylguanidine (MIBG) radiotherapy, and autologous stem cell transplant (SCT). I was told to take a decongestant to aleviate the pain. T1 - Neuroblastoma in adults. neuroblastoma, found in the immature nerve cells outside of the brain, often originating in the adrenal glands retinoblastoma, found in the retina pancreatoblastoma, found in the pancreas This risk‐based approach may be inappropriate in patients with adult neuroblastoma because of the much worse prognosis of adults with localized neuroblastoma compared with children with similar involvement, for whom surgery alone is often sufficient therapy. In this special form, the neuroblastoma has spread to the liver, to the skin, and/or to the bone marrow (in small amounts). AJR Am J Roentgenol. Am häufigsten entstehen sie im Nebennierenmark‎ (etwa 50 %) und im Bereich der Nervengeflechte beidseits der Wirbelsäule, im so ge… When the long-term adult neuroblastoma survival was examined in detail for 1-, 3-, 5-, 7-, and 10-year follow-up periods, there was continuous decrease in survival during the first 7 years after the diagnosis with subsequent stabilization for both observed (OS) and relative survival (RS) rates. At this point, she was referred to our institution for further evaluation. It’s is the most common cancer in babies under age 1. Involvement of the bone marrow can lead to complete hematopoietic failure and pancytopenia [6]. For metastatic disease, combination chemotherapy with or without radiation therapy may be fairly effective. It's often hard to diagnose neuroblastoma in the early stages, as initial symptoms are common ones – for example, aches and pains, loss of energy and loss of appetite. 2. 4. Olfactory neuroblastoma, also called esthesioneuroblastoma, is a very malignant, or cancerous, tumor believed to originate in the olfactory cells. Natl. Immunohistochemical studies demonstrated strong cytoplasmic staining for tyrosine hydroxylase and synaptophysin in the tumor cells (Figure 3). This syndrome is characterized by rapid, conjugate, multidirectional eye movements as well as myoclonus and ataxia [19]. Esthesioneuroblastoma (es-thee-zee-o-noo-row-blas-TOE-muh) is a rare type of cancer that begins in the upper portion of the nasal cavity.The area where esthesioneuroblastoma begins is separated from the brain by a bone that contains tiny holes that allow the nerves that control smell (olfactory nerves) to pass through. At our initial visit, the patient continued to complain of visual changes and headache. Hier lesen Sie alles Wichtige zu Ursachen, Behandlung & mehr! Tumors are of the sympathetic nerve chain and thus locations of primary tumors occur similarly in adults and children [12]. In children aged 6 months or younger, the disease sometimes goes away without treatment. Neurosurg. Our case report documents metastatic neuroblastoma occurring in a healthy 29-year-old woman whose course was complicated by an unusual presentation of elevated intracranial pressures. Small localized tumors have a high cure rate, up to 85-90% 7. It’s rare in children older than age 10. Psychiatr. It accounts for about 5% of all cancers of the nasal cavity and paranasal sinuses. 1 Definition; 2 Epidemiologie; 3 Ätiologie; 4 Pathologie; 5 Symptomatik; 6 Diagnostik. Unfortunately, imaging alone often struggles to distinguish between olfactory neuroblastomas and other aggressive malignancies in the region. The best outcomes occur in patients under 1 year of age who are diagnosed with early stage or stage 4S neuroblastoma but are without high-risk features such as n-myc amplification. Neuroblastoma may occur in similar sites to neuroendocrine tumors and should be considered particularly in patients of adolescent age and those with neurologic paraneoplastic symptoms. The olfactory cells, located in the upper rear of the … Neuroblastoma is a cancer that develops in immature cells, or neurons, of the sympathetic nervous system. Subsequent MIBG imaging obtained 25 days after therapy revealed persistent disease (Figure 4). Nancy J. Fischbein, William P. Dillon, A. James Barkovich. Neuroblastoma is a cancerous tumor. 3. Further testing was notable for an elevated 24-hour urine norepinephrine level of 694 μg (nl 0–135 μg). It develops as a solid tumor. These tumors are relatively slow-growing and thus, bony margins are often remodeled and resorbed, rather than being aggressively destroyed 3. Check for errors and try again. Neuroblastoma is an embryonal tumor of the sympathetic nervous system and is the third most common childhood cancer. The mass is of soft tissue attenuation, with relatively homogeneous enhancement 3. High uptake of 123I-metaiodobenzylguanidine related to olfactory neuroblastoma revealed by single-photon emission CT. AJNR Am J Neuroradiol. Low-risk neuroblastoma Children in the low-risk category may not need treatment right away. {"url":"/signup-modal-props.json?lang=us\u0026email="}, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":9341,"mcqUrl":"https://radiopaedia.org/articles/olfactory-neuroblastoma/questions/1979?lang=us"}, no distant metastases: 60% 5-year survival. PY - 2014/8/15. Though CNS involvement was suggested by dural enhancement seen on MRI, repeat cerebrospinal fluid (CSF) sampling over a period of months was negative by cytology. There is no consensus on the treatment for neuroblastoma in adults patients. Patients older than 18 months at the time of diagnosis typically present with unfavorable risk features including n-myc amplification. Wester K(1), Mørk S, Smievoll AI. Taking into account imaging and bone marrow findings, the pelvic mass was best classified as a composite (nodular) ganglioneuroblastoma. A complete blood count revealed a white blood cell count of 4,000/μL, hematocrit of 18%, platelets of 32,000/μL immature myeloid cells, and nucleated red cells consistent with a leukoerythroblastic smear. It has been suggested that olfactory neuroblastoma is actually part of the Ewing sarcoma group of tumors, rather than being related to neuroblastoma 5. A lumbar drain, later converted to a ventriculoperitoneal (VP) shunt, provided minimal symptomatic relief. She died 60 days following MIBG therapy. Contrast enhancement is often marked in both CT and MRI studies. Mary A. Thompson-Arildsen assessed initial pathology and edited the paper. In this review, we provide an overview of the epidemiology, clinical findings, and management of pediatric sphenoid bone and sphenoid sinus masses with an emphasis on imaging findings that may help to differentiate lesions. While our patient’s increased intracranial pressure may have been due to a paraneoplastic phenomenon, disease in the central nervous system (CNS) itself could not be excluded. Neuroblastoma is the third most common paediatric cancer. Initial computed tomography (CT) scans of the head, chest, abdomen, and pelvis was notable for a 5 cm soft tissue mass in the right pelvis, anterior to the sacrum with a lytic lesion in the left iliac crest (Figure 1). Das Neuroblastom ist die zweithäufigste Krebserkrankung im Kindesalter. When the CNS involvement is present, dural enhancement may occasionally be the only imaging abnormality, though often dural nodularity is additionally present [27]. Head and Neck Pathology. Although neuroblastoma is the most common extracranial solid tumor of childhood and infancy, we believe this is the first reported case of a conventional example arising in paranasal sinuses. However, this diagnosis is extremely rare in adults, with less than 100 cases reported in the literature. of nine adolescents and adults treated with a combination of doxorubicin, vincristine, cyclophosphamide, cisplatin, and etoposide, six experienced at least partial responses, three of which had a complete response or very good partial response [13]. (Esthesioneuroblastoma is another name for this type of cancer.) Background. Scintigraphy is also a convenient method for assessing the progression of the disease because a reduction in size can be well observed. Adults with metastatic neuroblastoma typically have a very poor prognosis [9]. Teaching atlas of brain imaging. Neuroblastoma is extremely rare in adults. A 35-year-old woman developed symptoms consistent with intracranial venous sinus occlusions that were demonstrated by MR angiography. In adults, neuroblastoma is often metastatic and portends an extremely poor overall survival. Zollinger LV, Wiggins RH, Cornelius RS et-al. There was a steady decline in the incidence of adult neuroblastoma from 0.47 cases per million per year in 1973–1977 to 0.12 cases per million per year in 1998–2002 [7]. Advances in classification and therapy have been recently made by an analysis of pediatric tumors. Olfactory neuroblastomas (esthesioneuroblastomas) arise from the olfactory nerves in the skull base and nasal cavity. AU - Cao, Yanna. Br J Radiol. Brain Tumor Treatment Brain Tumor When a cancer starts specifically in the nerves that affect your sense of smell, it is known as olfactory neuroblastoma. A lumbar puncture was performed with opening pressure of >55 cm H2O; cerebrospinal fluid (CSF) cytology was negative for involvement by neuroblastoma. 2000;21 (4): 717-20. Histology demonstrates variable differentiation, from well-formed neural tissue to undifferentiated neuroblasts with pseudorosette formation 2. Your child’s provider will monitor your child’s health carefully. Furthermore, outcomes in adults are significantly worse than those in children. Consolidation treatment with high dose chemotherapy and autologous stem cell transplant has been shown to improve survival in children and is an option in adults as well [14]. Additionally described neurologic paraneoplastic phenomena include Lambert-Eaton myasthenic syndrome, anti-Hu syndrome, ataxia, and idiopathic bilateral ptosis [21–24]. Other signs can i… New York; Thieme, 2000. Written informed consent was obtained from the patient’s next of kin for publication of this case report and accompanying images. Following cycle two, she developed worsening headaches and vision changes, with MRI findings of increased dural enhancement and compression of the sagittal sinuses without development of venous thrombosis. Rosengren JE, Jing BS, Wallace S et-al. She then received her second cycle of cyclophosphamide and topotecan despite thrombocytopenia (18,000/μL), given her degree of bone marrow infiltration with neuroblastoma. CT is particularly useful in assessing bony destruction, although it cannot distinguish olfactory neuroblastomas from other tumors that arise in the same region 2. She was then treated with therapeutic I131-MIBG (Figure 4), which was well tolerated. Children with neuroblastoma and their families have special needs. However, bone marrow evaluation revealed 80% marrow involvement of neuroblastoma with little evidence for differentiation. Patients often present late with larger tumors which can extend into the intracranial compartment (25-30% at diagnosis) and usually result in anosmia 2,3,7. An esthesioneuroblastoma diagnosis may involve: 1. The patient was treated with systemic chemotherapy, I131metaiodobenzylguanid… A special widespread form of neuroblastoma (known as stage 4S) occurs, but only during the first few months of life. Symptoms of the disease vary and are dependent on tumor location, presence of metastatic disease, and paraneoplastic syndromes. Neuroblastoma is a disease of the sympaticoadrenal neural crest cells and may occur in any part of the sympathetic nervous system. Olfactory neuroblastoma in the maxillary sinus - recent diagnosis. In general, the outlook is not as good as in younger patients, but the disease can often be controlled for many years due to its slow growth. In about 2 of 3 cases, the neuroblastoma has already spread to … Prognosis is significantly affected by the presence of distant metastases (see olfactory neuroblastoma staging). Neuroblastoma is the third most commonly occurring malignancy of the pediatric population, although it is extremely rare in the adult population. Sasajima T, Kinouchi H, Tomura N et-al.
