Intrasellar cavernous hemangioma is rare. There are no specific symptoms and the mass effect often mimics pituitary macroadenoma. We present one caseof intrasellar cavernous hemangioma that was misdiagnosed. Progressively decreasing vision was the main symptom in this case. The prolactin level was mildly increased but other biochemistry examinations were normal. Magnetic resonance imaging showed an enlarged pituitary fossa and an irregular solid tumor (33 mm × 22 mm × 22 mm) in the sella turcica and parasellar region. Subtotal removal in the case was performed through a transsphenoidal approach. Postoperatively, the patient's visual acuity improved. Through a literature review of 8 intrasellar cavernous hemangiomas, we found most lesions are likely to extend into the suprasellar cistern and cavernous sinus, and total resection is difficult. Transsphenoidal approach surgery should be applied for decom-pression of the optic nerve and biopsy, and stereotactic radiosurgery is preferable.
