An adenomyotic cyst is an extremely rare variation of cystic adenomyosis. The lesion consists of a large haemorrhagic cyst, which is partly or entirely surrounded by a solid wall. It can be entirely within the myometrium, submucosal, or subserosal and frequently is associated with symptoms of menorrhagia and dysmenorrhoea.
