Presentation
History of alleged fall and syncopal attack with 2 months history of recurrent vomiting.
Patient Data
A bilobulated heterogenous hyperdense extra-axial lesion ( evidence of CSF cleft) with peripheral rim calcifications seen at bi-frontal parasagittal region. The orbital roof, bilateral medial orbital walls and nasal septum are thinned out.
There are large expansile bi-fronto-ethmoidal sinuses masses which show homogenous intermediate signal intensity on T1W and T2W images with peripheral enhancement on post-contrast study. There is a mass effect with CSF cleft at both frontal regions however no associated perilesional brain edema. The mass extends until superior part of both orbits. Optic nerves are preserved.
Case Discussion
The patient had a bi-frontal craniotomy and excision of mucocele. Histopathological examination shows infected mucocele.
