Acute Pulmonary Thromboembolism Masquerading as Pneumocystis Ji-roveci Pneumonia in a Newly Detected HIV Positive Patient

Pneumocystis jiroveci pneumonia is a very well documented opportunistic infection in retro-positive individuals. Studies have shown that venous and arterial thrombosis occurs with increased frequency in patients infected with HIV. The reported frequency of venous thromboembolism varies between 0.19% to 7.63%/ year and that of pulmonary thromboembolism around 0.26%. But here, we report a case in which a newly detected retro-positive patient had both pneumocystis jiroveci pneumonia and pulmonary thromboembolism leading to a diagnostic delay of PCP pneumonia.
