title: Metastasis from a primary angiosarcoma of the scalp to the colon: sonographic and CT findings.
abstract: We report a case of metastasis to the colon from a primary angiosarcoma of the scalp in a 61-year-old Japanese man and describe the sonographic features and CT findings, with a brief discussion of the clinical and histopathologic findings. Although this entity is extremely rare, it should be considered when a patient with prior diagnosis of angiosarcoma in another organ has focal thickening with preserved compressibility of the wall of the colon.
