Weaver's bottom

Published:November 03, 2022DOI:
      A 77-year-old woman presented with a 40-day history of gradually increasing mass in the left buttock, and she complained of pain on sitting. She reported having long term sedentary activities, like knitting and viewing TV. Physical examination revealed a soft and well-defined mass located in the left gluteal region, approximately 5 cm in diameter (Fig. 1A). Pelvis magnetic resonance (MR) demonstrated a thin-walled cystic lesion with high signal intensity on T2-weighted image, attached to the ischial tuberosity (Fig. 1B). Maximum intensity projection stereoscopically displayed the mass, measuring 8 × 6 × 4 cm, located inferior to the ischial tuberosity (Fig. 1C). The patient underwent excision of the mass. The mass had a thin, white to gray wall, containing a large amount of serous fluid. Histologic analysis revealed bursitis, showing a cyst wall consisting of fibrous and granulation tissue, hemorrhage and a small amount of chronic inflammatory cells (Fig. 1D). The patient was feeling well at 4 months of follow-up.
