From: Incomplete paresis of the sciatic nerve due to massive atypical lipoma of the pelvis: a case report
Pelvic MR and CT imaging. A) Massive fatty tumor with hyperintense appearance in the noncontrast T1-weighted (TR/TE, 168/5) axial image. B) The sagittal noncontrast T1-weighted (TR/TE, 600/10) image demonstrated a thin septum inside the tumor. C) The tumor showed a complete signal loss in the fat saturation sequences (TR/TE 5660/48). D) Axial noncontrast multidetector CT image demonstrated a massive soft-tissue pelvic tumor occupying the sciatic foramen. The mean density was -100HE and identified the fatty tissue characteristics. E) Magnification of the axial noncontrast multidetector CT image revealed nodular appearance of the septa (see arrows). F) Coronal reconstructed noncontrast multidetector CT image showed the expansive soft-tissue mass inside and outside the pelvic. Adjacent organs und muscles were displaced.
