Double Metachronous Pituitary Microadenoma: Literature Review and Case Report

Pituitary adenomas, which are benign, slow-growing neoplasms, are commonly associated with hormonal overproduction. They rank as the third most prevalent intracranial tumor, following gliomas and meningiomas. Although double pituitary adenomas are infrequent, they manifest when two adenomas develop within a single pituitary gland. These dual adenomas exhibit typical immunohistochemical and histopathological features. They can be further classified into two distinct types: contiguous and clearly distinct. Neuroradiological imaging facilitates the identification of clearly distinct tumors. We present imaging findings from a rare case of a double pituitary microadenoma. Early diagnosis of this uncommon condition is crucial to prevent potential complications.
