Presentation Transcript
abdominal cyst
ABDOMINAL CYST

An abdominal CT scan revealed a large right upper quadrant cyst measuring 14x17x21 cm ( lateral, anteroposterior and craniocaudal)There was mass effect upon the liver and duodenum. The cyst had a thin smooth wall with internal fluid and high density material consistent with a blood clot.

renal cyst
RENAL CYST

polycystic kidney disease

In PKD fluid-filled cysts develop giving the kidneys a honeycomb appearance. It is one of the most common inherited disorders, and the fourth commonest cause of kidney failure.

POLYCYSTIC KIDNEY DISEASE

In polycystic kidney disease many fluid-filled cysts develop in the kidneys. Gradually these cysts replace the normal kidney tissue enlarging the kidneys but making them less and less able to function normally. Eventually the kidneys fail completely

ascites

Ascites is the abnormal collection of fluid in the abdominal cavity, most often as a result of chronic liver disease.

ASCITES
appendicits
APPENDICITS

An axial slice of a CT scan done with the use of intravenous and oral contrast is presented. The arrow points to an area of soft tissue induration within the retrocecal fat. There is a rim like area of higher attenuation within this area. The structure is fluid filled. These features are compatible with a diagnosis of acute appendicitis and the presence of rupture cannot be excluded.

diverticulits
DIVERTICULITS

Diverticulitis is inflammation or infection of small pouches, called diverticula, that develop along the walls of your intestines. The formation of the pouches themselves is a relatively benign condition known as diverticulosis.

The pouches can develop anywhere on the digestive tract, but they most commonly form at the end of the descending and sigmoid colons, and they also frequently occur on the first section of the small intestine (although they rarely cause problems there).

abdominal abscess
ABDOMINAL ABSCESS

Psoas abscess (blue arrow), and abscess dissecting anteriorly in transversalis fascia.

liver mets
LIVER METS

Lung cancer, small cell. Contrast-enhanced CT scan of the abdomen. Axial section through the liver shows multiple hypoattenuating areas in the liver. Poorly defined margins, attenuation greater than that of water, and scattered distribution in a patient with known lung cancer is most consistent with metastatic disease.

wilms tumor

Wilms tumor, also called nephroblastoma, is a cancer that originates in the kidney. The disease gets its name from a German doctor, Max Wilms, who wrote one of the first medical articles about it in 1899.

Ninety percent of all kidney cancers in children are Wilms tumor. The remaining ten percent are rare forms of childhood kidney cancers: clear cell sarcoma of the kidney, malignant rhabdoid tumor of the kidney, and occasionally renal cell carcinoma

WILMS TUMOR
kidney cancer
KIDNEY CANCER

Kidney cancer affects some 30,000 people in the United States each year, and close to 12,000 die from the disease. It is the eighth most common cancer in men and the tenth most common in women. Smoking is the major risk factor,

pheochromocytoma
PHEOCHROMOCYTOMA

Pheochromocytoma is a tumor of the adrenal gland that causes excess release of epinephrine and norepinephrine, hormones that regulate heart rate and blood pressure

slide29

A cavernous hepatic hemangioma is the most common non-cancerous tumor of the liver. It is believed to be a congenital defect, and is usually not discovered until medical pictures are taken of the liver for some other reason.
