Cytomegalovirus pneumonia in a background of central nervous system tuberculosis

Abstract

Abstract A 32‐year‐old patient, who was on treatment for tuberculous meningitis complicated with venous sinus thrombosis, was referred to the medical unit as he developed new onset fever, cough and shortness of breath. He was in respiratory distress and needed intubation. Investigations revealed elevated liver enzymes, leukopenia, spherocytosis and lower lobe predominant consolidations and diffuse nodules in the high‐resolution computed tomography. He was suspected to have cytomegalovirus (CMV) pneumonia with the above results, and further investigations revealed an extremely elevated CMV viral load. He was treated with ganciclovir followed by valganciclovir for a total of 42 days resulting in a complete recovery. Liver functions resolved with anti‐viral treatment, and he was started on full anti‐tuberculosis (TB) treatment. Further investigations did not reveal evidence of immunosuppression. Association of CMV and TB is explained genetically, although clinical association is rarely described. The presence of either infection should lead to higher degree of suspicion of the respective other condition in relevant clinical setting.
