Calcium pyrophosphate dihydrate deposition disease of the spleen

Abstract

Calcium pyrophosphate dihydrate deposition disease (CPPD), also known as pseudogout or chondrocalcinosis, is a variety of metabolic arthropathy caused by the deposition of calcium pyrophosphate dihydrate crystals in and around joints. Despite many case reports, extra-articular CPPD often goes unrecognized. Here, we report a unique case of pancreatic tail pseudocyst and CPPD of the spleen. To the best of our knowledge, CPPD of the spleen has not been reported in the literature.
