 LUNG ABSCESS LIP HIV AIDS and LYMPHOMA
27 year old male with a history of perinatal HIV with intermittent highly active antiretroviral therapy (HAART) compliance with a CD4 count of < 50 with biopsy confirmed B cell lymphoma of the liver, s/p CHOP therapy , chronic esophageal strictures s/p dilatations, esophageal candidiasis, LIP, bronchiectasis pancreatitis, and portal vein and splenic vein thrombosis.
Initial Chest X-ray shows a diffuse reticular pattern with cystic changes dominant at the bases.
CT at that time confirmed the presence of diffuse cystic changes with the largest cysts at the lung bases. Ascites and splenomegaly are also present
He presented one month later with fever and neutropenia.
CT showed an abscess cavity in the right upper lobe in the right upper lobe, thickened distal esophagus with edematous wall, atrophic gastritis and ascites. Bronchovascular thickening along a bronchiectatic segment in the right upper lobe was present in the last CT

Doughnut sign. A normal lateral chest radiograph is shown depicting several of the anatomic landmarks used to localize a subcarinal mass (A: 1, posterior wall of the bronchus intermedius; 2, left upper lobe bronchus; 3, right upper lobe bronchus; 4, approximate level of the carina). Lateral radiograph of the chest (B) shows added density within the infrahilar window representative of subcarinal lymphadenopathy in a patient with non-Hodgkin lymphoma. Follow-up CT of the chest confirmed the finding of subcarinal lymphadenopathy (C).

Human Herpes Virus 8 and Primary Effusion Lymphoma (PEL)

Axial CT ? Human Herpes Virus 8 and primary Effusion Lymphoma (PEL)
Axial CT scan with contrast of 71-year-old male shows bilateral complex and loculated effusions with thickened enhancing pleura. Pleural tap of the left effusion revealed evidence of lymphoma likely related to the patients underlying herpes virus infection. An entity called primary effusion lymphoma (PEL) is a rapidly progressing non-Hodgkin?s B-cell lymphoma that develops in body cavities
