Atypical Pulmonary Tuberculosis as the First Manifestation of Advanced HIV Disease-Diagnostic Difficulties

Tuberculosis (TB) is the leading cause of morbidity, hospitalisations, and mortality in people living with HIV (PLWH). The lower CD4+ T-lymphocyte count in the course of HIV infection, the higher risk of active TB, and the higher odds for atypical clinical and radiologic TB presentation. These HIV-related alterations in TB presentation may cause diagnostic problems in patients not knowing they are infected with HIV. We report on a patient without any background medical conditions, who was referred to a hospital with a 4-month history of chest and feet pains, mild dry cough, fatigue, reduced appetite, and decreasing body weight. Chest X-ray revealed mediastinal lymphadenopathy, bilateral reticulonodular parenchymal opacities, and pleural effusion. A preliminary diagnosis of lymphoma, possibly with a superimposed infection was established. Further differential diagnostic process revealed pulmonary TB in the course of advanced HIV-1 disease, with a CD4+ T-lymphocyte count of 107 cells/mm³. The patient completed anti-tuberculous therapy and successfully continues on antiretroviral treatment. This case underlines the importance of screening for HIV in patients with newly diagnosed TB.
