A 55-year-old male with newly diagnosed HIV infection who presented with high fever and generalized abdominal pain. His CD4⁺ lymphocyte count was also significantly low at the time of his presentation. Axial plane postcontrast CT scan revealed several small hypoattenuating lesions scattered throughout the liver parenchyma (arrows). Based on his clinical context, the lesions were suggestive of pneumocystis jirovecii infection. Also note mild splenomegaly in this case which is an important suggestive finding for disseminated pneumocystis infection. Post treatment follow up confirmed almost complete regression of the imaging findings (not shown)
