Radiological evaluation of Ovarian Dermoid

Background: Ovarian dermoid cyst is the most common ovarian neoplasm. It accounts for ~15% of all ovarian neoplasms. They tend to be identified in young women, typically around the age of 30 years. These slow-growing tumor contain elements from multiple germ cell layers and are easily detected with ultrasound and much better by CT scan and MRI. Materials and methods: Patients presented to Radiology department with known case of dermoid cysts of ovary or in whom accidental diagnosis of ovarian dermoid cyst was made eventually. Evaluation of ovarian dermoid with Ultrasound machine (Logiq P9 GE), CT scan Siemens (16 slice) and MRI Philips (1.5 Tim + dot system). Results: In our study we found that 25 (100%) patients had ovarian dermoid, 20 (80%) patients were of age group 21years to 40 years, 4 (16%) patients were of 41-60 years and 1 (4%) patients were of 0-20 year age group. In diagnosis of ovarian dermoid our results showed that CT scan was more sensitive (96%) than USG (92% sensitivity). Conclusion: Detection and morphological characterization of ovarian dermoid can be easily done on ultrasound. MRI and CT scan are useful adjunct to USG in its characterization and detection of associated pathology. In USG, when ovary shows heterogeneously hyperechoic lesion with fat fluid level without any vascularity highly suggestive of ovarian dermoid.
