Cerebral aspergillosis – CT scans, CLL patient DS.

Patient diagnosed with Stage C Chronic Lymphocytic Leukaemia, treated in the MRC CLL4 study, with prednisolone for 4 weeks followed by oral chlorambucil for 7 days. Patient developed severe pneumonia due to pseudomonas and staphylococcus. Following treatment with broad spectrum antibiotics and 1 week of Abelcet, patient was readmitted with headache, disorientation and fever. CT brain scans showed 3 ring enhancing lesions, aspirated material showed neutrophils but grew aspergillus. Patient now improved on Abelcet (4 mg/kg) and oral itrconazole suspension 200mg b.d.
