Presentation
Left pelvic pain.
Patient Data
There is a lobulated left ovarian mass (6.5 x 4 x 3 cm), composed of numerous small masses of high signal on T1 and T2, attenuated on fat sequences with moderate heterogeneous enhancement on postcontrast sequences. A small floating nodule (1 cm) is noted within the largest mass of intermediate to high signal on T1, low signal on T2, with no enhancement.
The left ovary shows numerous small follicles.
Normal appearance of the uterus.
Minimal free fluid is noted in Douglas pouch.
Case Discussion
MRI features of a left ovarian mass of fatty signal, hypointense on fat suppression sequences, suggestive of a dermoid cyst.
