title: Malignant intrasellar meningioma presenting as an invasive pituitary macroadenoma: A rare case report and literature review.
abstract: Intrasellar meningiomas are rare tumors that have the ability to mimic non-functioning pituitary adenomas. The majority of meningiomas are slow-growing and benign, therefore an intrasellar meningioma with malignant histological features is extremely rare. The present study describes the case of a malignant diaphragm meningioma that was controlled through combined chemotherapy, following subtotal surgical resection. The patient's symptoms ceased and no tumor recurrence was detected at the 3-year follow-up. Hormone levels were also observed as normal. Further investigation of similar cases may aid in achieving an accurate pre-operative diagnosis. This would prove particularly beneficial in regards to intrasellar meningiomas due to their specific location and surgical treatment. The present study analyzes the requirement of chemotherapy for the treatment of these unique tumors.
