Urinary bladder polyp:

Transabdominal ultrasound image showing a small, but clearly visualized solid polypoid tissue projecting into the urinary bladder close to the bladder neck. The query here is: is this mass a bladder mucosal polyp or a beak of prostatic tissue (the patient was a middle aged male with lower urinary tract obstructive symptoms).















Transrectal ultrasound image shows the polypoid mass of 12 x 5 mm. size, emanating from the bladder mucosa close to the prostate. Color Doppler ultrasound shows considerable flow within the urinary bladder polyp. This amount of vascularity is highly suggestive that this mass of tissue is a vascular mucosal polyp and not an enlarged median lobe of prostate.

Large sebaceous cyst in unusual location

This sebaceous cyst was huge, at almost 7 x 5 cms. and located on the buttock of this elderly male patient. The ultrasound image shows a typical hypoechoic, solid, mildly inhomogenous appearance. The patient presented with complaints related to the prostate, ignoring this large epidermoid cyst.















Color Doppler image of the same cyst shows no vascularity within the mass. A sebaceous cyst contains oily, gel like semisolid material that has been unable to escape. If infected, this can turn into an abscess.

Sludge balls in the Gall bladder:

Found these two echogenic masses in the gall bladder in a young, adult female patient. The question was: are these GB polyps or sludge balls. Change in posture caused them to move.
So, that ruled out polyps. Ultrasound image above shows the sludge balls in the gall bladder (arrows).















Power Doppler image (above) shows no flow within the gall bladder lesions- that again supported my inference that these were not gall bladder polyps.















High resolution ultrasound image (high frequency transducer) gave a good close up view of the gall bladder with the two sludge balls almost "kissing" each other... ;-)

An interesting case of mass in Riedel's lobe of liver

At first, ultrasound imaging of the right kidney shows a possible mass in the lower pole of kidney.














The above ultrasound image seems to confirm this possibility.














Imaging of the right lobe of liver shows the mass to be connected to a tongue of liver tissue extending from the right lobe of liver. The mass is at the tip of the long beak of liver tissue draped over the anterior surface of right kidney. This is the typical appearance of a Riedel's lobe of liver with a mass located in its tip.






























The gall bladder is normal.

Large serous cystadenoma of ovary:

This patient complained of a swelling of the abdomen and vague pain. Ultrasound imaging of the pelvis showed a huge, cystic mass measuring 14 x 9 cms., with few septae traversing through it. No solid tissue was present within this cyst. The fluid within the cyst appeared to be clear serous type with scanty particulate matter within it. The kidneys appeared normal suggesting no pressure effects on the ureters despite the large size of the cystic tumor. The bladder was clearly identified separate from the cyst, thus ruling out a diverticulum of the bladder. Color Doppler image showed no significant vascularity in the septae. Final diagnosis from these ultrasound images was serous cystadenoma of ovary. With such large masses/ cysts it is not possible to determine the exact origin of the lesion/ or the side from which it originates.

Seminal vesicle calculus and hemospermia:

Seminal vesicle calculi are a known cause of passage of blood in semen. This patient had hemospermia. TRUS images show a calculus in right seminal vesicle. Possibly such calculi cause irritation and trauma to the delicate walls of the seminal vesicle resulting in hemorrhage. But surgery may be the final alternative in this case.
