Male versus Female Pelvis – Labeled Radiographic Anatomy

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

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. Therefore, I created the following image to discuss the differences between the female and male pelvis. 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.

History: 50 year old male with chest pain.  A bulla is a thin-walled hole in the lung that must be larger than 10 mm. 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

Round Atelectasis

History: 60 year old male undergoing CT of the thorax for follow up of chest x-ray abnormality.  This is a classic appearance of round atelectasis. Look again at the image above. Notice the calcified pleural plaque along the area of atelectasis. Round atelectasis is most frequently seen in asbestos related pleural plaques. Other terms for … Continue reading

Leydig Cell Tumor of Testicle

History: 35 year old male with right sided scrotal pain.  The differential for this lesion is broad, however, in the absence of trauma or symptoms of infection, benign and malignant neoplasms are considered. The diagnosis in this case was Leydig cell tumor, which is a tumor of the testicular interstitial cells and is categorized with … Continue reading

Scrotal Fibrous Pseudotumor

History: 55 year old male with incidental lump in his scrotum.  The imaging here is essentially diagnostic of scrotal fibrous pseudotumor, particularly, the marked hypointensity on T2W MR imaging. 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
