Dermoid cysts are also called teratoma because they refer to developmentally advanced tissues in an array. Figure 7c. (b) T1-weighted gradient-echo MR image (200/4.2) shows the mass (thick arrow) with high-signal-intensity fat (F). (a) Transverse transabdominal US image shows a heterogenous mass in the cul-de-sac (arrowheads). Such thyroid tissue can occur as a minor component ofmature cystic teratomas, but in struma ovarii it is the predominant or sole tissue type. While the small cysts cause no issue, the large ones cause immense pain. 30, No. (c) On a fat-suppressed T1-weighted gradient-echo MR image (200/2.1), the signal of the lipid material within the mass is suppressed (arrow). No fat is evident in these lesions. 5, 27 June 2012 | RadioGraphics, Vol. Figure 9a.
