Abstract
A 29-year-old Ethiopian man presented with marked bilateral visual loss, headache, hypopituitarism and significant hyponatraemia (115 mmol/L). A brain MRI scan demonstrated a large, lobulated, sellar and suprasellar mass, elevating the floor of the 3rd ventricle and compressing the optic chiasm. The patient underwent a transphenoidal resection of the mass followed by a craniotomy 10 days later. Histological examination demonstrated a Hyams’ grade III neuroblastoma with ectopic expression of vasopressin. He underwent fractionated radiotherapy at a dose of 60 Gy in 30 fractions. Fourteen months after the onset, he is well with no neuroimaging evidence of tumour recurrence. His serum and urine sodium are completely normalised.
