| 説明 | Crospovidone has a coral-like appearance with a basophilic outer coat and a pink inner layer. It is an insoluble polymer of N-vinyl-2-pyrrolidone that is used as a disintegrant in pharmaceutical tablets. It embolizes to the lungs when aqueous suspensions of pulverized tablets are injected intravenously in drug abusers (IVDA) It is also found in the gastrointestinal tract following ingestion of various types of tablets. The precise architecture of histologically processed crospovidone can vary by medication. This and other features of crospovidone are very well discussed and illustrated in tinyurl.com/yajl3oru.The very unusual feature of this case is that particles of crospovidone were also observed in the kidneys and brain indicating passage through the pulmonary capillaries. The size of the particle in one of the images of kidney is much larger than the diameter of the pulmonary capillaries thus raising the question of a possible pulmonary arteriovenous shunt.
