Here we report a 79-year-old woman who presented with a 7-day history of headache, nausea, vomiting, and was found to have proptosis and ptosis. Laboratory findings showed hyponatremia, hypocortisolism, secondary hypothyroidism and low follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels. CT angiography (CTA) showed a vascular lesion in sella causing a mass affect on the pituitary gland which proved to be a carotid cavernous fistula (CCF) by conventional angiography. The lesion was subsequently treated with coil placement and patients hyponatremia was successfully treated with corticosteroid and thyroid hormone replacement. Though rare, CCF should be considered in the differential diagnosis of sellar lesions. Also, in patients with CCF hyponatremia, hypotension or signs of hypothyroidism should warrant a work-up for pituitary function.
