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.

Because 40 to 50 percent of dog mammary tumors have estrogen receptors, [11] spaying is recommended by many veterinarians.
The network explains on its website that it features 24/7 programming "created to meet specific attributes of a dog's sense of vision and hearing and supports their natural behavior patterns."
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.
