All 52 leiomyomas were classified into two histopathologic subtypes from their histopathologic findings: ordinary leiomyoma (N = 47), predominantly composed of typical whorls of smooth muscle cells, though degenerative changes (hyaline degeneration, myxomatous degeneration, cystic change, fatty changes, etc.) Of 11 tumors assigned at surgery to the submucosal group, 10 had been accurately defined with MR. On MR, myomas associated with hypermenorrhea produced an anatomic disruption of the "junctional zone" (the low-intensity band seen at the myometrium-endometrium junction on T2 contrast images). While focal hydropic degeneration may be relatively common, the complete cyst transformation of a myoma is exceptionally rare [2], [3], [4]. Infrequently, cystic or myxoid degeneration occurred in the tumor. Contrast between tumor and myometrium was -16% on the T1 contrast image and increased to -44 +/- 16% on the T2 contrast image. eCollection 2014.
