[Fever, pleural effusion and osteolytic lesion in a patient with HIV infection]

We present the case of a 28 year old patient who came for consultation on a fever of up to 40.8 degrees C, pleuritic pain on the right side and the appearance of a painful mass in the lower left extremity of four days evolution. Computerised axial tomography (CAT) showed the existence of a condensation in the middle lobe of the right lung with associated pleural effusion and bilateral miliary pattern. The echographic study of the lower left extremity showed a mass of soft parts with a cystic aspect with destruction of the cortical of the fibula and osseous destruction. Magnetic resonance confirmed the presence of osteomyelitis in the left fibula and of an abscess; Mycobacterium tuberculosis was also isolated in three samples of sputum that led to a diagnosis of disseminated tuberculosis with miliary lung affectation, peroneous osteomyelitis and tuberculous abscess of the soft parts. Anti-tuberculosis treatment was started (riphampicine, isoniacide and pirazinamide) followed, two weeks later, with antiretroviral treatment (AZT, 3TC and NVP). The patient developed a clinical picture of generalised cutaneous eruption that disappeared following the replacement of the riphampicine by etambutol. Due to the persistence of the mass of soft parts following five weeks of anti-tuberculosis treatment, we proceeded to surgical draining of the abscess. The subsequent evolution was favourable, with the patient remaining asymptomatic one month after hospital discharge.
