AIM: To analyse the incidental findings during computertomographic angiography (CTA) diagnostic work-up in patients with arteriogenic erectile dysfunction (ED).

PATIENTS AND METHODS: The medical records of all patients with suspected arteriogenic ED were entered into a database. Risk factors and underlying comorbidities were also collected. Pathological CTA findings were extracted from the CT readings and entered into the data-base. Incidental findings on CTA were classified as those requiring immediate medical treatment, requiring deferred medical treatment or of no clinical importance.

RESULTS: A total of 200 patients underwent CTA for suspected arteriogenic ED. Mean patient age was 59.6 ± 11.7 years. Of these, 181 patients (90.5%) had obstructions of erection-related arteries. In 168 patients (84.0%), CTA showed multiple incidental pathological findings. Eighty-five of 200 patients (42.5%) exhibited incidental findings requiring immediate further medical workup and/or treatment: coronary artery calcification was diagnosed in 75/200 (37.5%), aorto-iliac aneurysms in 8/200 (4%) of patients and incidentally detected embolism in 1/200 patient. Pancreatic and liver tumours were less frequent (incidence 1.5% and 1%, respectively). Incidental findings requiring deferred medical workup and/or treatment were detected in 175/200 patients (87.5%). The findings with the highest prevalence were liver steatosis followed bycolon diverticulosis and prostate hyperplasia. Findings of little to no clinical importance were reported in 117 (58.5%) patients. These included uncomplicated renal cysts, spinal degeneration and renal vascular anomalies. Almost every second patient presenting with ED had an incidental find-ing which required immediate treatment.
