A 36 year old man with acute myeloid leukaemia presented with recurrent episodes of fever and a three day history of right sided pleuritic pain and left upper abdominal pain after two cycles of chemotherapy. The patient had received several broad spectrum antibiotics with no clinical improvement. On examination, his temperature was 40.2°C and there was no evidence of Hickman catheter infection both in terms of local evidence and catheter blood cultures. Coarse crackles were noted over the base of the right lung. The liver, spleen, and peripheral lymph nodes were not enlarged. Bone marrow examination showed hypocellular marrow with no excess of blast cells. The neutrophil count was less than 0.05 × 109/l for three weeks. Cultures of the blood were repeatedly negative. Chest radiography after two courses of chemotherapy was normal. Computed tomograms of the thorax and abdomen are shown in figs 1 and2.
