The following images are from WikiRadiography (WetPaint) here. See more differences between the male and female pelvis. Advertisements

The Differences Between the Male and Female Pelvis

Recently I shared a case of Peyronies disease. Many people thought it was showing an intrauterine device.

The male pelvic inlet is narrower than the female pelvic inlet and is more heart shaped, whereas the female pelvic inlet is … Continue reading

Lung Bullae – Bullous emphysema.

The hole contains no parenchyma, and there is a high contrast between the cavity and normal lung parenchyma. Emphysema is classified typically as either paraseptal or centrilobular (although, another type is … Continue reading

A scrotal fibrous pseudotumor typically arises from the tunica albuginea or vaginalis and can break free to form a “scrotal mouse.”

Testicular Seminoma – Differential Diagnosis of a Testicular Mass on Ultrasound

History: 35 year old male with 2 week history of right sided scrotal swelling, persistent after a trial of antibiotics.  The differential in this case given the absence of change with antibiotic treatment and absence of symptoms of infection, includes neoplasms such as testicular seminoma, and non-seminomatous tumors such as embryonal cell (the type that … Continue reading
