Extrathoracic solitary fibrous tumor of the pelvic peritoneum with central malignant degeneration on CT and MRI.
We describe a 61-year-old man who presented with an extrathoracic solitary fibrous tumor (SFT) of the pelvic peritoneum with central malignant degeneration as seen on computed tomography (CT), magnetic resonance imaging (MRI), and histopathology. When a central focus of heterogeneity and variable contrast enhancement are identified within a fibrous tumor of the pelvis on CT or MRI, malignant degeneration of an extrathoracic SFT, although rare, should be considered as a diagnostic possibility.
