title: Ischiogluteal bursitis: multimodality imaging findings.
abstract: Ischiogluteal bursitis is a rare, infrequently recognized condition. Two cases of ischiogluteal bursitis in an 80-year-old man and a 75-year-old woman are presented. Both patients presented with a painful buttock mass. Contrast-enhanced multiplanar reconstruction computed tomography scans revealed a lesion with peripheral enhancement inferior to the ischial tuberosity. Magnetic resonance imaging revealed a lesion with low or intermediate signal intensity on T1-weighted images. T2-weighted images revealed a lesion with high signal intensity. Postcontrast magnetic resonance imaging scans revealed peripheral enhancement of the lesion. The multimodality imaging findings of ischiogluteal bursitis have not been described previously. Ischiogluteal bursitis should be considered in the differential diagnosis of a buttock mass.
