Scalloping Characteristics in a Patient with Extra- Cranial Hemangioma

Abstract

SummaryInfantile hemangiomas are the most common benign tumors of infancy and childhood with a reported incidence of 4% to 10% in infants. We report of a 9 year-old male child with a history of progressively increasing swelling over the right eyebrow region. The lesion was present since childhood; however, it increased in in size over the previous 3–4 months. The CT scan showed scalloping over the right supra-orbital ridge with an intact bone. The child underwent total excision of the lesion. A characteristic scalloping seen on imaging (depression in the outer or inner table of the skull) can help differentiate lesions of extracranial and intracranial origins.

Multifocal intraosseous calvarial hemangioma misdiagnosed as subgaleal lipoma

“…The CT findings of intraosseous hemangioma may appear as an osteolytic defect with “soap bubble,” “honeycomb” or “sunburst” appearances. “Honeycomb” appearances correspond with a scattering of radiodense spots in the radiolucent hollow [6-8]. This radiologic finding is due to osteolytic activity of the mass and secondary reactive osteoblastic remodeling with trabecular bone.…”
