Lymphoid adenohypophysitis with radiologic and clinical findings resembling a pituitary tumor.

Lymphoid hypophysit is is an apparently rare condition whi ch was initially reported as a postmortem finding in six patients [1 -6]. In these patients, death was related to the re latively rapid development of hypopituitarism. It has recently been described in four living patients [7-9]. In the previous case reported by us, visual fi elds were normal and a computed tomography (CT) scan was normal although the sella was ballooned at tomography. However, as the present case shows, the radi olog ical and c linical finding s may c lose ly simulate a pituitary tumor with suprasellar extension .
