MRI findings of an ovarian dermoid cyst with malignant transformation.
The ovarian dermoid cyst is the most common ovarian tumor. However, malignant transformation developing from a dermoid cyst is very rare. Because of this rarity, few reports exist of preoperative diagnosis of this tumor by MRI. We report MRI findings from a 69-year-old patient with a malignant transformation (squamous cell carcinoma with sarcomatoid features) in a right ovarian dermoid cyst.
