A rare case of chronic granulomatous inflammation with actinomycosis in the bladder was diagnosed after surgical resection. This finding highlights actinomycosis as a consideration for inflammatory abdominal masses.

Area of Science:

  • Urology
  • Pathology
  • Medical Imaging

Background:

  • Actinomycosis is a rare bacterial infection that can affect various parts of the body, including the urinary tract.
  • Vesical actinomycosis, specifically, is exceptionally uncommon, with limited case reports in the medical literature.

Observation:

  • A 55-year-old woman presented with a 5-year history of lower abdominal pain.
  • Imaging studies (CT and MRI) identified a heterogeneous mass adjacent to the bladder.
  • Initial CT-guided biopsy yielded inconclusive results, showing only inflammatory cells.

Findings:

  • Surgical resection of the mass, including parts of the bladder and peritoneum, was performed for diagnosis.
  • Pathological examination revealed chronic granulomatous inflammation consistent with actinomycosis.

  • This represents the 12th reported case of vesical actinomycosis in Japan.

    • Implications:

    • The case underscores the importance of considering actinomycosis in the differential diagnosis of inflammatory abdominal masses, even in the urological field.
    • Advanced imaging and biopsy are crucial for diagnosis, but surgical resection may be necessary for definitive pathological confirmation.
    • Increased awareness among clinicians can lead to earlier diagnosis and appropriate management of this rare condition.
