Figure 1: Temporal artery biopsy viewed in the longitudinal axis demonstrates striking beading of the wall with nodular distensions causing luminal narrowing (a). Note the bulbous end (arrow, a) that shows dense inflammation expanding the medial coat. Close-up view of the vessel in the transverse plane (b) reveals expansion of the medial coat by multiple aggregates of epitheloid cells forming granulomas (b, arrows) with large multinucleate giant cells (c, arrows). Several of the multinucleate giant cells have ingested fragments of elastica from the internal elastic lamina (d, arrow)
