Comparative Study
Exogenous lipoid pneumonia: high-resolution CT findings.
The aim of this study was to assess high-resolution computed tomography (HRCT) findings of exogenous lipoid pneumonia. High-resolution computed tomography was obtained in 25 patients with proven exogenous lipoid pneumonia resulting from aspiration of squalene (derived from shark liver oil). Diagnosis was based on biopsy (n = 9), bronchoalveolar lavage (n = 8), or sputum cytology and clinical findings (n = 8). ⋯ Three patients simultaneously had two different patterns at different lobes of the lung. The HRCT findings of lipoid pneumonia are ground-glass opacities, consolidation, and interstitial abnormalities. These HRCT findings with appropriate inquiries could be useful for diagnosis of exogenous lipoid pneumonia.

Ascariasis is a well-known cause of acute cholangitis and cholecystitis; however, very rarely do worms penetrate and colonize the liver parenchyma. Here we present the unique radiological demonstration (US, CT and ERCP) of hepatobiliary ascariasis in which worm was first alive in the parenchyma of the liver and subsequently died and formed liver abscess.

The aim of this study was to report our experience on the management of superior vena cava obstruction (SVCO) secondary to malignant disease, using endovascular procedures. Twenty-six patients with SVCO due to primary or secondary tumors of the lung or the mediastinum, or catheter inserted for treatment of an extra-thoracic neoplasm, had an endovascular therapy which consisted of stenting, angioplasty, thrombo-aspiration or local fibrinolysis. Immediately after the procedure, rapid relief of symptoms occurred in 24 (90 %) of the patients. ⋯ At 6 months the primary patency rate was 83 % and the secondary patency rate was 89 %. Endovascular treatment of SVCOs is a simple and safe procedure to restore the patency of the superior vena cava in malignant SVCO. It should be indicated in most cases as first-line treatment and performed as early as possible.

Chest radiographs and high-resolution chest CT scans were performed in a 30-year-old man with a history of intravenous drug abuse and diffuse micronodular infiltrates. Transbronchial biopsy gave a diagnosis of cellulose granulomatosis of the lung. Cellulose granulomatosis should be considered in the differential diagnosis of pulmonary interstitial disease, especially in the setting of intravenous drug abuse.
