Background
Sciatic hernia is considered to be the rarest hernia of pelvic floor with less than one hundred reports published worldwide. Lipoma in the hernia sac is even more unique pathology with only few cases reported in the literature. We report a case of gluteal lipoma protruding into pelvis, displacing rectum with bladder and presenting as a sciatic hernia.
Case presentation
A 53-year-old male presented with an expanding, slightly reducible, right gluteal painful mass, back pain, dull pressure in lower abdomen and perianal region radiating to the right buttock, urgent urination and defecation. Lower back pain lasts for more than 7 years, other symptoms—6 months. No spinal pathology was found on X-ray. On examination patient seemed well nourished, BMI 29, abdomen was soft, without palpable masses or signs of peritonitis. Digital rectal examination showed no pathology. There was a reducible lump on the lateral side of right gluteus. Computer tomography (CT scan) demonstrated a large intra- and extra-pelvic fatty mass traversing the greater sciatic foramen. The tumor was surgically removed through lower middle laparotomy approach. Subsequent pathological examination revealed lipoma. The patient recovered uneventfully, was discharged 8 days later. MRI scan was advised following 1 year after the surgery.
Conclusion
The presence of a gluteal mass should always suggest the possibility of a sciatic hernia.
