A, Longitudinal sonogram showing a mass (M) posterior to the uterus (U) and appearing separate from it.B, Coronal sonogram showing a cystic mass posterior to the uterus.The mass shows uniform homogeneous, low‐level echoes and posterior through‐transmission. -. On ultrasound, the classic appearance of an ordinary (nondegenerated) leiomyoma is a round or oval circumscribed hypoechoic solid mass, often with associated posterior shadowing due to calcifications or interface of the margins of the leiomyoma with the normal myometrium.

The tumors varied from less than 1 cm to 18 cm in diameter. Leiomyomas typically demonstrate distinct low signal intensity relative to that of the myometrium on T2-weighted images and intermediate signal intensity on T1-weighted images. Mark AS, Hricak H, Heinrichs LW, Hendrickson MR, Winkler ML, Bachica JA, Stickler JE. These characteristic signal intensities are attributed to extensive hyalinization, which occurs in more than 60% of uterine leiomyomas (,1,,5,,6). We describe three such cases of perinodular hydropic degeneration in leiomyoma with two being extra uterine, thus imposing diagnostic difficulty clinically as well on histology.

Smooth muscle cells were elongated with eosinophilic or occasional fibrillar cytoplasm and distinct cell membranes. Even in areas with high cellularity, Hyaline degeneration appears similar to a non-degenerated. Leiomyomas free of degenerative changes emitted homogeneous signals of low intensity. Histology of most of the leiomyomas showed a whorled (fascicular) pattern of smooth muscle bundles separated by well-vascularized connective tissue. Case Type.
