A lobular capillary hemangioma, previously known as a pyogenic granuloma, is a benign vascular lesion of the skin or mucous membrane. We report a case of capillary hemangioma of lobular subtype in the calvarium of a 28-year-old pregnant woman which presented as a sore and rapidly growing bulge over the left fronto-parietal region. Magnetic resonance imaging of the brain and skull showed an expansive tumor with brain displacement, skull erosion, and scalp infiltration. The tumor was surgically removed, and histopathological examination showed a capillary hemangioma of lobular subtype. To the best of our knowledge, this is the first report of a lobular capillary hemangioma in the calvarium, and it represents a rarity to be considered among the many other differential diagnoses for neurosurgical lesions involving the skull, especially in pregnant women.
