Here we report a rare case of capillary hemangioma (CH) in a 28-year-old woman suffering from gradual worsening diplopia at 28 weeks of pregnancy. Magnetic resonance imaging (MRI) showed a mass lesion (about 3 cm in diameter) in the right parasellar region. We decided to observe as she was pregnant, and had no symptoms other than right abducent nerve palsy. Fortunately, her symptoms did not worsen until delivery. Computed tomography, enhanced MRI, and angiography after delivery revealed that the lesion was highly calcified and vascularized. A dorsum sellae meningioma or highly calcified pituitary adenoma was suspected and the endoscopic transsphenoidal approach was used for tumor removal.The postoperative course was uneventful. The histological diagnosis was CH.Intracranial CHs or CHs of skull are rare vascular tumors. These tumors are reportedly more common in female patients and may change in size in adults according to menstrual cycle and pregnancy. Only six cases, including that of the present study, were diagnosed during the perinatal period. Some of them experienced rapid symptom progression and tumor growth in their course; thus, we should pay further attention to pregnant or peripartum patients with brain tumor, suspected hemangiomas.
