Peribronchovascular thickening

Pulmonary

Kaposi sarcoma in a human immunodeficiency virus – infected woman: a case report. HRCT scan obtained with lung window shows diffuse peribronchovascular thickening and small nodules bilaterally. There are also nodules in the fissures and interlobular septal thickening.

Pulmonary

involvement in Kaposi sarcoma: correlation between imaging and pathology. A and B. High-resolution CT scans of two patients with pulmonary KS showing peribronchovascular thickening and irregular narrowing of the bronchial lumen.

Pulmonary

involvement in Kaposi sarcoma: correlation between imaging and pathology. High-resolution CT scan at the level of the main bronchi of a patient with pulmonary KS, showing diffuse ill-defined large nodules and paracardiac peribronchovascular thickening.

Pulmonary

involvement in Kaposi sarcoma: correlation between imaging and pathology. High-resolution CT scan of a patient with pulmonary KS at the level of the main bronchi shows ground-glass attenuation areas in the posterior regions of both lungs, which correspond to pulmonary hemorrhage. Peribronchovascular thickening is observed in the right lung, as well as bilateral pleural effusion.

Pulmonary

involvement in Kaposi sarcoma: correlation between imaging and pathology. A to D. High-resolution CT scans (A and B) of two patients with pulmonary KS that demonstrate marked peribronchovascular and interlobular septal thickening and the presence of small parenchimal nodules. Photomicrographs of histologic specimen show tumor cells infiltrating the periarteriolar connective tissue (C), and a neoplastic parenchymal nodule with indistinct borders (D) (HE, ×40).

Pulmonary

involvement in Kaposi sarcoma: correlation between imaging and pathology. A to D. High-resolution CT scans at the level of the upper lobe (A) and the lower lobe (B), of two patients with pulmonary KS, show extensive interlobular septal and peribronchovascular thickening. Photomicrographs of histologic specimens (C and D) show thickening of interlobular septa due to edema and tumor cells infiltration (HE, ×40).
