RESUMO
A thrombosed, leaking aneurysm of the popliteal artery, mimicking a soft tissue sarcoma both clinically and by MRI examination, is described. It may be difficult to separate a leaking, thrombosed aneurysm from an inflammatory response secondary to a sarcoma with intralesional hemorrhage. An aneurysm should, however, be considered in the differential diagnosis if the mass is present in a well-recognized location for aneurysm and is associated with vascular engulfment and signs of subacute or chronic hemorrhage.

Hypodense liver lesions with attenuation coefficients indicative of fat density were seen on CT of three patients followed up for suspected metastatic spread of gastrointestinal malignancy. Knowledge of previous hepatic surgery using omental packing for hemostasis in the setting of liver trauma or lobectomy was useful in preventing a false-positive interpretation of postoperative complications.
