Popliteal venous aneurysm.

Two new cases of popliteal venous aneurysm, confirmed with findings from venography, are added to seven previously reported cases revealed in the authors' search of the English-language literature. This rare anomaly usually shows as recurrent pulmonary emboli in patients with no underlying predisposition to deep venous thrombosis. Physical examination is usually not helpful in the diagnosis. Results of combined real-time and Doppler ultrasound should indicate the diagnosis, but venography is necessary for confirmation and further anatomic detail. Surgical treatment has been fraught with complications. Eight patients, including these two new cases, have undergone surgery, and none have had a recurrence of pulmonary embolism following surgery.

The antimetastatic activity of enkephalin-like peptides.

[Met5]Enkephalin and [Leu5]enkephalin, two naturally occurring opioid-like peptides were found to decrease the number of spontaneous pulmonary metastases in C57BL/6J mice implanted in the foot pad with the B16-BL6 melanoma. The number of such metastatic nodules were reduced more than 2-fold. This effect was noted after several different injection schedules. In addition to their effect on metastasis the growth rate of the primary tumor was also decreased by these compounds.

Intravascular bronchioloalveolar tumor: CT and pathologic correlation.

Intravascular bronchioloalveolar tumor of the lung is an unusual neoplasm that usually presents as multiple pulmonary nodules in asymptomatic young women. The course of the disease is often indolent with some patients eventually dying of respiratory failure secondary to progressive tumor infiltration of the pulmonary interstitium. The cell of origin appears to be an endothelial cell, and epithelioid hemangioendothelioma of liver or other soft tissues is a pathologically identical neoplasm. Open lung biopsy is necessary for diagnosis. The radiologist should be aware of this tumor and suggest the diagnosis in the appropriate clinical setting.
