    Introduction. Opportunistic pulmonary infections frequently occur after liver transplantation, and affect mortality and morbidity significantly. The purpose of this study was to define the incidence, types, and imaging characteristics of pulmonary infections in liver transplant recipients with multidetector CT (MD CT) evaluation. Methods. Thirty-five adult transplant recipients diagnosed with a pulmonary infection within the first 45 days posttransplantation were reviewed retrospectively from March 2002 to December 2013. MDCT features were evaluated retrospectively by 2 radiologists in consensus. All diagnoses were made by sputum analysis, cultures, biopsies, and postmortem histopathologic evaluation. Results. Pneumococcus pneumonia was found in 7 patients. Five patients had nonspecific pneumonia, Candidiasis, Klebsiella, and Aspergillosis separately. S aureus pneumonia was detected in 2 patients and the other 2 patients had Escherichia coli pneumonia. Two patients had active tuberculosis and 1 patient had Acinetobacter pneumonia also. Four main MDCT patterns were identified: patchy infiltrations (10%), tree-in-bud pattern (9.5%), ground-glass opacity (8.5%), and nodules with halo sign (6%). One patient had a cavitary lesion owing to tuberculosis. Conclusion. Although the incidence of pulmonary complications in liver recipients was relatively low, mortality from serious infections was high. Care must be taken with pulmonary infectious complications in the posttransplant period. For any suspicious case, MDCT evaluation for specific patterns of early accurate diagnosis is very important.

    PANCREATIC CYSTIC LYMPHANGIOMA: DIAGNOSTIC APPROACH WITH MDCT AND MR IMAGING
    (2014) Macin, G.; Hekimoglu, K.; Uner, H.; Tarhan, C.
    Lymphangiomas are rare congenital benign tumors arising from the lymphatic system mostly encountered in the neck and axillary regions of pediatric patients. Pancreatic cystic lymphangiomas very rarely occur in adults. Radio-logically, the lesion may mimic pancreatic carcinoma and should be considered in the differential diagnosis of any patient found to have an abdominal cystic mass. In this article, we present a 50-year-old man who presented with pain in the upper abdomen, nausea, and abdominal swelling. On computed tomography (CT) and magnetic resonance (MR) imaging, a gross septated cystic lesion was detected in the upper abdomen which extended from the pancreatic corpus to the left liver lobe. The patient underwent complete resection of tumor Pathology revealed a cystic lymphangioma.
