RESUMEN
We report the case of an ectopic pituitary adenoma in a 65-year-old man with an empty sella who initially presented with right ptosis and eyelid edema and headache. Neuroimaging studies revealed a large tumoral process at the height of the clivus, with partial destruction of surrounding bone structure. He underwent transphenoidal surgery and histopathologic examination, including immunohistochemical studies, revealed a prolactin-producing pituitary adenoma. A careful review of the literature was done.

Metastases to the breast from extramammary neoplasms are very rare. Correct diagnosis of breast malignancy is important for establishing appropriate management. Here we report a 57-year old male patient with breast metastasis from large cell neuroendocrine carcinoma (LCNEC) which was diagnosed with ultrasonography-guided-core-biopsy.

We report a case of emphysematous cholecystitis. We also offer a review of the literature, emphasizing the clinical features, pathogenesis, imaging features and treatment of this surgical condition. Early recognition and surgical consultation are vital in these patients. The significance of plain abdominal radiographs, ultrasonography, CT and RM studies is discussed. Diagnostic problems are mentioned to help understand this rare clinical condition.
