Inguinoscrotal Pathology on Computed Tomography: An Alternative Perspective

Area of Science:

• Radiology
• Medical Imaging
• Diagnostic Imaging

Background:

• Computed tomography (CT) is generally not the primary imaging modality for inguinoscrotal pathology due to limitations in soft tissue contrast resolution and gonadal radiation exposure.
• Alternative techniques like magnetic resonance imaging (MRI) and ultrasonography offer superior soft tissue detail and avoid ionizing radiation for inguinoscrotal assessments.
• Despite limitations, CT can reveal testicular and inguinoscrotal pathology as incidental findings or extensions of intra-abdominal processes.

Purpose of the Study:

• To present a pictorial review of testicular and inguinoscrotal pathology as depicted by computed tomography (CT).
• To illustrate the CT appearance of diverse conditions affecting the inguinoscrotal region, including vascular, neoplastic, traumatic, infectious, and inflammatory diseases.
• To showcase CT findings in complications of abdominal surgeries and congenital anomalies within the inguinoscrotal area.

Main Methods:

• A pictorial review approach was utilized, compiling representative CT images of various inguinoscrotal pathologies.
• The review encompasses conditions identified incidentally, as extensions of abdominal disease, or in specific clinical scenarios like trauma and infection.
• Illustrations cover congenital anomalies, benign processes, and complications related to abdominal surgical interventions.

Main Results:

• Computed tomography (CT) can identify a spectrum of inguinoscrotal pathologies, including vascular abnormalities, neoplasms, trauma-related injuries, and infectious/inflammatory processes.
• Incidental detection of testicular and inguinoscrotal abnormalities is common on CT scans performed for other indications.
• CT is valuable in assessing testicular injury associated with pelvic trauma and in evaluating perineal infections with scrotal extension.

Conclusions:

• While not the first-choice imaging modality, CT plays a role in evaluating specific inguinoscrotal conditions, particularly in the context of trauma, infection, and incidental findings.
• Familiarity with the CT appearance of these pathologies is crucial for accurate diagnosis and management.
• This review provides a visual guide to the diverse manifestations of inguinoscrotal diseases on CT.
