Abstract:
This case report presents CT-guided transperineal biopsy as an alternative method for diagnosis of prostate cancer in a patient with anorectal stenosis. A 69-year-old male had a history of anorectal surgeries. Conventional transrectal biopsy was unfeasible due to anorectal stenosis. The CT-guided transperineal biopsy was successfully performed using a cranio-caudal puncture technique, revealing adenocarcinoma. After the biopsy, the patient received appropriate hormone therapy and radiation therapy. This case report highlights the feasibility and safety of CT-guided transperineal biopsy for the patients with anorectal complications.
