title: Hypopituitarism with arachnoid cyst.
abstract: Arachnoid cysts, most characteristically situated in the middle cranial fossa, have been described at other situations, in the posterior fossa and in the interpeduncular region. A case of primary amenorrhoea, obesity, with short stature, proved to be associated with a huge arachnoid cyst involving the L. middle and anterior cranial fossae; and pituitary fossa, producing panhypopituitarism with right faciobrachial paresis, normal visual fields and visual acuity. No evidence of progress of the lesion has been found after 3 years of observation, and further conservative management with regular CT scanning and oestrogen replacements is proposed.
