title: [Paravesical granuloma after inguinal herniorrhaphy].
abstract: Paravesical granuloma is a rare complication after inguinal herniorrhaphy. We report a case of this rare disease and review 27 previously reported cases. A 70-year-old male presented with hematopyuria. He had undergone right inguinal herniorrhaphy five years earlier. On presentation, the right inguinal area was wet with exudate. Cystoscopy revealed edematous mucosa on the right side of the bladder dome, but transurethral bladder biopsy demonstrated no malignancy. CT identified a 2-cm diameter mass with heterogeneous appearance on the right side of the bladder dome. Treatment with antibiotics proved ineffective and en bloc excision of the tumor with partial cystectomy was performed. Symptoms subsequently resolved completely. Histopathologically, the tumor represented inflammatory granuloma, and a mesh thought to be a remnant from the previous herniorrhaphy was found in the central portion of the tumor. Paravesical granuloma should be considered for patients with continuous hematopyuria and a history of inguinal herniorrhaphy.
