Radiographic patterns of opportunistic lung infections and Kaposi sarcoma in homosexual men.
Thirty patients with lung involvement with Pneumocystis carinii and other opportunistic organisms, many of whom also had Kaposi sarcoma, were seen from December 1980 through March 1982. Clinical manifestations consisted of a prodrome of weeks to months with weight loss, fever, and malaise. When clinical pneumonia became apparent, four distinct radiographic patterns were identified. Pneumocystis carinii was uniformly present, and the most common pattern encountered was a relatively symmetric, homogeneous perihilar pneumonia that progressed to diffuse consolidation. Asymmetric and focal infiltrates were seen in patients who proved to have concomitant opportunistic infection, most commonly fungal in all but two cases. A third pattern of nodular and linear densities with or without adenopathy was seen in patients without pneumonia who had biopsy-positive Kaposi sarcoma involving the lung parenchyma. A fourth pattern represented a combination of any of the first three, and these patients had multiple infections as well as Kaposi sarcoma in the lung. Any significant change in the radiograph indicating progression of disease while on therapy prompted a rebiopsy, and in five of 10 patients other infections and/or Kaposi sarcoma were identified.

The use of computed tomography in the assessment of cardiac masses.
Computed tomography has been found to be a useful tool in the evaluation of cardiac masses. It can be most effacious in the detection of a lesion and in the delineation of its size and location, as well as the demonstration of its relationships to intra- and extracardiac structures. It can be especially useful in areas of the heart where echocardiography can be difficult. This is particularly true for the left atrium, where lesions such as small thrombi can be missed.

Intraaortic mass after repair of an aortic dissection.
After graft repair of an ascending aortic aneurysm, a patient was seen by us with a chest x-ray film indicating a retained foreign body. Mediastinal exploration had been unrevealing. Transesophageal echocardiography demonstrated the nature and exact location of the foreign body and therefore was instrumental in directing its retrieval.

Computed tomography of pectoral flaps.
We report two cases of rotated pectoral flaps performed following sternal debridement. The key to the diagnosis is recognition that the characteristic central area of low density represents fat and not fluid. This, along with the finding of sharply defined fascial planes and an absence of one or both pectoralis major muscles, should allow confident differentiation between this entity and a postoperative chest wall abscess.

AIDS associated bronchiectasis: CT features.
The occurrence of bronchiectasis has only rarely been noted among the protean manifestations of HIV infection in the lungs. We retrospectively identified bronchiectasis on CT scans in 12 HIV + and/or AIDS patients in the absence of either documented mycobacterial infection or a history of prior recurrent pyogenic infection. Pneumonitis was documented in 10 of 12 cases. In eight cases, bronchiectasis was associated with episodes of pyogenic infection; four of these patients also had documented opportunistic infections, including three cases of Pneumocystis carinii pneumonia (PCP). Two patients had infection due solely to PCP. In two cases, bronchiectasis was found in association with one case each of lymphocytic interstitial pneumonitis and nonspecific interstitial pneumonitis, respectively. Although the true incidence of bronchiectasis in this population remains to be established, in our experience bronchiectasis should be considered among the varied pulmonary manifestations of HIV infection. Furthermore, the seemingly rapid development and extent of bronchiectasis in this population suggest an accelerated form of the disease.
