Cranial encephaloceles are rare conditions, which are more commonly seen in the anterior rather than in
the middle cranial fossa. Temporal lobe encephalocele can present with a variety of clinical symptoms,
amongst which include occult or symptomatic cerebrospinal fluid (CSF) fistula. We present a case of
a patient with a short history of rhinorrhea who was found to have a CSF pool in the sphenoid sinus
and right anteromedial temporosphenoidal encephalocele, which mimics sphenoid mucocoele, a much
more common entity. This case highlights the imaging findings of temporosphenoidal encephalocoele
and the diagnostic clues in differentiating this rare condition from the commoner mimics.
