Atypical aesthesioneuroblastoma: CT and MRI findings

  • 27 Accesses

  • 8 Citations


Aesthesioneuroblastoma is an uncommon tumour of the superior nasal cavity, originating from the olfactory mucosa. Usually no specific radiological features indicate the diagnosis; normally these tumours are seen on CT as homogeneous, enhacing, soft tissue masses causing bone remodelling. Typical but quite nonspecific MRI findings include high signal on T2-weighted images and strong enhancement after gadolinium. The extent of tumour in the paranasal sinuses and anterior cranial fossa is best assessed with MRI after intravenous gadolinium, and this is considered as the most accurate method for assessing preoperative resectability. We report an aesthesioneuroblastoma in an atypical location, with extensive calcification.
