Metastatic lesions involving the sella: Report of three cases and review of the literature

Metastatic cancer must be considered as a possibility for 1 intrasellar masses. Newer treatment modalities, such as gamma knife radiosurgery needs to be explored for these lesions. Three cases of intrasellar metastatic lesions were retrospectively reviewed. Presenting complaints, radiographic studies, operative procedure, and histopathological confirmation were recorded for each patient. All had an unknown primary malignancy prior to the presentation with the intrasellar lesion detected by magnetic resonance imaging (MRI). Presenting symptoms were diplopia with extraocular movement deficits in all patients. Transsphenoidal resection or biopsy was performed. Histopathological vealed small cell carcinoma in two patients and plasmacytoma in one. All patients received postoperative radiation and/or chemotherapy. Survival following initial presentation was 2 months and 6 months for two of the patients; the third patient is alive at 2-month follow-up.
