[Isolated pulmonary giant cell arteritis: a case report and literature review].

Objective: To study the clinical and pathological characteristics of isolated pulmonary giant cell arteritis and its differential diagnosis.

Methods: The pathological data of a patient with isolated pulmonary giant cell arteritis were studied, and the literature was reviewed.

Results: The walls of the pulmonary artery and its major lobar branches were thickened, and the blood vessels were occluded by organizing thrombosis. The arterial wall was infiltrated by lymphocytes, mononuclear cells and some multinuclear giant cells.

Conclusions: Isolated pulmonary giant cell arteritis is a rare disease which can be definitely diagnosed by angiography and histopathology.
