Panhypopituitarism secondary to metastasis of the central nervous system due to a bronchogenic adenocarcinoma

Abstract

A 45-year-old woman with a history of heavy extabaquism presented with chronic headache in the occipital region irradiated to the temporal region associated with decreased visual acuity of the left eye. The picture worsened in the last six months and was associated with polydipsia and polyuria. She presented a syncopal picture with retrograde amnesia, for which a contrast computed tomography (CT) of the skull was performed, which showed multiple parenchymal brain and cerebellar lesions compatible with metastasis. Hormonal study was done to evaluate the hypophyseal function evidencing a secondary panhypopituitarism. A primary neoplastic focus was detected by a contrast chest CT scan, showing a spiculated lesion in the right upper lobe suggestive of bronchogenic carcinoma. A biopsy was subsequently taken by fibrobronchoscopy, which confirmed the diagnosis of a bronchogenic adenocarcinoma by histopathology and immunohistochemistry
