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).

Pulmonary involvement in Kaposi sarcoma: correlation between imaging and pathology. A and B. High-resolution CT scan (A) shows areas of ground-glass attenuation and interlobular septal thickening in the upper lobes. A crazy-paving pattern is observed in the right upper lobe. Photomicrograph of histologic section (B) demonstrates infiltration of the interlobular septa due to edema and neoplastic cells and also edema filling the alveolar airspace (HE, ×40).

There are many causes of interlobular septal thickening, and this should be distinguished from intralobular septal thickening. Thickening of the interlobular septa can be smooth, nodular or irregular, with many entities able to cause more than one pattern.
