Figure 1 Contrast-enhanced axial CT abdomen demonstrating a large oval hypodense lesion [HU 30-70] (long arrow) within a large lobulated uterus with stretching of the myometrium. This is histopathologically proven as degenerated leiomyoma with large areas of necrosis and hyalinization, and inflammation is noted in both the fibroid and the myometrium, which simulates an endometrial fluid collection or hydrometra. A smaller separate heterogeneously enhancing lesion with whorl appearance (short arrow) is seen to the right side of the uterus and which is proven early degenerated leiomyoma.
