Misdiagnosis of olfactory neuroblastoma [PDF]
Neurosurgical Focus, 2002 Object Olfactory neuroblastoma (ON) is a rare neoplasm arising from the olfactory epithelium and found in the upper nasal cavity. The authors studied the frequency with which ON is misdiagnosed with other tumors of the paranasal sinuses such as neuroendocrine carcinoma (NEC), pituitary adenoma, melanoma ...

Olfactory Neuroblastoma and Olfactory Ventricle [PDF]
The Neuroradiology Journal, 2014 A case of dumbbell nasal and intracerebral olfactory neuroblastoma (ONB) related to possible seeding through an “olfactory ventricle” in the olfactory bulb and nerve is reported. This anatomic variant was recognized at operation for the first time: it consists of a hollow cavity within the olfactory bulb and nerve which may be connected to the ...

Delayed Diagnosis of Olfactory Neuroblastoma During the SARS-CoV-2 Pandemic
Annals of Internal Medicine: Clinical Cases, 2023 The COVID-19 pandemic has resulted in a delay in cancer diagnosis and treatment during this time. A potential cause of delayed diagnosis that may be underrecognized is a patient misinterpretation of symptoms. To illustrate this point, we present the case
