Retroperitoneal bleeding is an accumulation of blood in the retroperitoneal space. Signs and symptoms may include abdominal or upper leg pain , hematuria , and shock . It can be caused by major trauma or by non-traumatic mechanisms.
An abdominal mass is any localized enlargement or swelling in the human abdomen.Depending on its location, the abdominal mass may be caused by an enlarged liver (hepatomegaly), enlarged spleen (splenomegaly), protruding kidney, a pancreatic mass, a retroperitoneal mass (a mass in the posterior of the peritoneum), an abdominal aortic aneurysm, or various tumours, such as those caused by ...
Desmoplastic small-round-cell tumor (DSRCT) is an aggressive and rare cancer that primarily occurs as masses in the abdomen. [4] Other areas affected may include the lymph nodes, the lining of the abdomen, diaphragm, spleen, liver, chest wall, skull, spinal cord, large intestine, small intestine, bladder, brain, lungs, testicles, ovaries, and the pelvis.
The procedure is common in the treatment of Stage I and II non-seminomatous germ cell tumors. [2] In seminomas, another form of testicular cancer, radiation therapy is generally preferred to the invasive RPLND procedure. [4] Whether RPLND is needed after orchiectomy depends on the type of tumor and its stage. RPLND may be performed to remove ...
CT is the best diagnostic modality: [25] a confluent mass surrounding the aorta [6] and common iliac arteries can be seen. On MRI, it has low T1 signal intensity and variable T2 signal. Malignant retroperitoneal fibrosis usually gives uneven MRI signals, is bulky, extends above the origins of renal arteries, or displaces the aorta anteriorly.
Retroperitoneal DDL is the most common, surgically unaccessible and serious form of DDL: it has a recurrence rate of 66% and a five-year overall survival rate of 54%. [31] The primary treatment option for retroperitoneal DDL is surgical resection.
Pseudomyxoma peritonei (PMP) is a clinical condition caused by cancerous cells (mucinous adenocarcinoma) that produce abundant mucin or gelatinous ascites. [1] The tumors cause fibrosis of tissues and impede digestion or organ function, and if left untreated, the tumors and mucin they produce will fill the abdominal cavity.
Male to female predominance of 3:1 to 4:1. [1] Related to the left hemidiaphragm in 90% of cases. May present as a subdiaphragmatic or retroperitoneal mass. In general, the arterial supply of comes from an aberrant vessel from thoracic aorta. It usually drains via the systemic venous system to the right atrium, vena cava, or azygous systems.
