From: Magnetic resonance imaging features of alveolar soft part sarcoma: report of 14 cases
A 27-year-old man with alveolar soft part sarcoma. (a) Coronal T1-weighted image shows an isointense signal tumor in the left thigh muscle with an ill-defined border in a 27-year-old man. There are intra- and extratumoral tubular flow voids (arrows). (b) Coronal T2-weighted image reveals the hyperintense signal tumor with signal voids (arrows). (c) Coronal fat-suppressed T2-weighted image displays the hyperintense signal tumor with peritumoral edema. (d) Coronal fat-suppressed post-contrast T1-weighted image demonstrates intense inhomogeneous enhancement of the tumor. (e) Magnetic resonance angiography obtained from dynamic gadolinium-enhanced imaging study shows tortuous, dilated vessels in and around the tumor. (f) A photomicrograph shows oval to polygonal cells with eosinophilic cytoplasm and a nest-like pattern of arrangement (Hematoxylin and eosin, ×20).
