Leiomyom des Uterus mit hyaliner Degeneration
Hyaline degeneration is the most common form of degeneration that can occur in a uterine leiomyoma.
Epidemiology
It is thought to occur in up to 60% of uterine leiomyomas .
Pathology
As with many other types of degeneration, it happens when fibroids outgrow their blood supply . Hyaline degeneration involves the presence of homogeneous eosinophilic bands or plaques in the extracellular space, which represent the accumulation of proteinaceous tissue .
Radiographic features
MRI
Typical signal characteristics of a leiomyoma with hyaline or calcific degeneration are difficult to distinguish from non-degenerated fibroids on pelvic MRI. Areas of calcification can appear as signal voids on MRI .
Therefore typical characteristics include :
- T1: isointense
- T2: hypointense
- T1 C+ (Gd): low enhancement in comparison to regular leiomyoma
