(en) A 47-year-old woman was referred to the hospital with non-productive coughing, fever, fatigue, weight loss. She was known for a 3-year-long standing HIV infection. Blood tests showed an increased C-reactive protein (CRP: 3.6 mg/dl, nl < 1 mg/dl), an increased lactate deshydrogenase (LDH: 875 UI/L, nl < 248 UI/L) and an Epstein-Barr virus reactivation. A chest radiograph was performed (not shown), followed by a contrast-enhanced CT scan of the thorax (Fig. 1) and the abdomen (Fig. 2). Based on the CT scan examination, a pleural puncture was performed for cytological analysis (Fig. 3)
