A 82-year-old woman presented with vomiting, reduced level of consciousness, and worsening mental state. Computed tomography showed a contrast-enhanced extra-axial lesion in the left frontal operculum, although no intracranial mass lesion was identifiable from magnetic resonance imaging taken 2 years earlier. Complete surgical excision was performed and histopathological examination diagnosed benign capillary hemangioma consisting of a variety of dilated capillary blood vessels lined by endothelial cells.
This is the first description of rapid growth of an intracranial capillary hemangioma in an elderly woman. These lesions are exceedingly rare in the elderly population, but still show the capacity for rapid growth. Complete excision would prevent further recurrence 1).
A 58-year-old Caucasian man, who presented with a 4-month history of increasing low back pain and gait difficulty. Objective neurologic examination revealed a severe paraparetic symptomatology without any sphincter involvement.
Spinal magnetic resonance imaging (MRI) showed an extradural mass formation situated dorsally at the level of thoracic vertebrae T2 to T4.
A laminectomy was performed with total removal of the mass; histology suggested a highly vascularized lesion with lobular architecture, which seems a very rare case, compatible with a capillary hemangioma.
A careful follow-up for the next 4 years, including control MRIs every postoperative year, showed a very good neurologic condition of the patient and no recurrence on imaging findings 2).
