What is the normal scrotal wall thickness?

• A. 2-8 mm
• B. 6-12 mm
• C. 0.5-1.5 cm
• D. 8-12 mm

Answer: (A)

Normal scrotal wall thickness on ultrasound is about 2 to 8 millimeters. The scrotal wall is the thin layer of skin and dartos fascia surrounding the testis, and you measure the distance from the outer scrotal surface to the inner tunica vaginalis edge at the thickest point, typically in a transverse view. Values in this 2–8 mm range are considered normal. If the wall is thicker—approaching or exceeding roughly 8–10 mm—that suggests edema or inflammation, such as scrotal edema, cellulitis, or epididymo-orchitis. Other ranges either miss the normal lower limit or extend beyond the typical upper limit, so they’re not considered normal.
