High-frequency ultrasonography and contrast-enhanced ultrasound for the evaluation of testicular capillary hemangioma: A case report

RATIONALE: Testicular capillary hemangioma (TCH) is a rare benign tumor of the testis. To the authors’ knowledge, there is currently only a few literatures describing the use of contrast-enhanced ultrasound (CEUS) to diagnose TCH. Accurate preoperative diagnosis of benign tumors can avoid orchiectomy. A case of TCH evaluated using high-frequency ultrasound and CEUS is presented. PATIENT CONCERNS: A 21-year-old male presented with a right testicular mass during a routine physical examination, and was admitted to the authors’ hospital for definitive diagnosis and treatment. DIAGNOSES: Combined gray-scale, color Doppler ultrasonography, and CEUS did not exclude the possibility that the right testicular lesion may be a benign tumor. Combined with morphological and immunohistochemical staining results, a pathological diagnosis of TCH was considered. INTERVENTIONS: The patient underwent right orchiectomy under general anesthesia, which proceeded smoothly. OUTCOMES: At the 12-month follow-up, the patient was completely asymptomatic and resumed all daily activities. LESSONS: TCH is a rare benign tumor and lacks extensive previous data in imaging findings. If TCH can be diagnosed accurately before surgery, excessive or inappropriate treatment of benign lesions can be minimized, which will be beneficial to the physical and psychological health of patients.
