An ultrasound scan was performed at 8th gestational week in a 28-year-old primigravida which revealed an 8 x 6 x 7 cm smooth-walled, mixed echogenic mass with irregular inner contents in the left ovary (Figure 1) and a viable singleton intrauterine pregnancy.

Power Doppler with the use of minimum-maximum mode revealed a hyperechoic solid part and speckled appearance of sebaceous contents suggesting a dermoid cyst (Figure 2). Power Doppler didnot detect any vascularization neither at the periphery nor in the central region of the cyst.
