Spontaneous CSF rhinorrhoea and sphenoid encephalocele as manifestations of idiopathic intracranial hypertension

A woman in her 40s with a Body Mass Index (BMI) of 34 kg/m² presented with a 1-year history of holocranial headaches and persistent watery nasal discharge. The headaches, initially non-positional, became orthostatic around the time she developed watery nasal discharge. The discharge was continuous, non-sniffable, and increased on bending forward, features suggestive of a cerebrospinal fluid (CSF) rhinorrhea. There was no history of trauma, neurosurgery, epilepsy, or systemic comorbidities. Neurological examination was unremarkable, including cranial nerve and motor-sensory assessments. funduscopy revealed no papilledema.
