It occupies the anterior abdomen displacing the adjacent bowel to the right side, and compresses both distal ureters causing mild hydroureteronephrosis. This lesion shows no enhancement and is predominantly of fat density containing calcifications and a fluid-fat level. It measures 18 x 8 x 16 cm The right ovary shows a thin-walled cyst with mixed contents along with the presence of the acoustic shadow. There is no vascularity in the cyst wall. The cyst measures 99 x 74 x 71 mm. The right ovarian parenchyma is compressed and displaced peripherally. The left ovary shows a normal follicular pattern. Uterus shows normal myometrial echopattern. There is no endometrial thickening Ultrasound is the preferred imaging modality. Typically an ovarian dermoid is seen as a cystic adnexal mass with some mural components. Most lesions are unilocular. The spectrum of sonographic features includes: diffusely or partially echogenic mass with posterior sound attenuation owing to sebaceous material and hair within the cyst cavit Mature cystic teratomas are referred to as dermoid cysts. Dermoids derived from more than one germ layer, and they can include hair, fat, muscle, teeth, skin, endocrine tissue. Fat/fluid level is diagnostic and found in 12% of ovarian dermoid. Ro.. Intracranial epidermoid cysts are uncommon congenital lesions which account for about 1% of all intracranial tumors. They result from inclusion of ectodermal elements during neural tube closure, and typically present in middle age due to mass effect on adjacent structures. Their content, derived from desquamated epithelial cells, mimic
Fat suppression sequences are used to differentiate between the ovarian dermoid cyst and hemorrhagic/endometrioma cyst as dermoid cyst contains fat and its signal will be suppressed in fat suppression. In the recent case, the complex cystic mass show T2 shading similar to endometrioma, but the presence of the Rokitansky nodule and small fat. Dermoid cysts are a term used almost always interchangeably with mature cystic teratomas. Dermoids derive from more than one germ layer and they can include hair, fat, muscle, teeth, skin and endocrine tissue. A fat-fluid level is diagnostic and found in 12% of ovarian dermoids. CT findings of a dermoid cyst are fat attenuation within a cyst and may be associated with calcification or a fat-fluid level

Fine needle aspiration was carried out and cytology analysis showed keratinous thick fluid with squamous cells and fat suggesting the diagnosis of dermoid cyst and the patient has been referred for surgical management. Inguinal dermoid cyst or m.. Spinal dermoid cysts are uni or multilocular cystic tumors lined by squamous epithelium containing skin appendages (hair follicles, sweat glands, sebaceous glands) 6. They are congenital in origin. Forty percent are intramedullary, and 60% are e.. Haouimi, A. Ovarian dermoid cyst. Case study, Radiopaedia.org.

No solid enhancing component can be identified. Medially it displaces the superior rectus/LPS complex medially, and the lateral rectus inframedially, and results in moderate proptosis. Laterally a tail of the cyst extends through the lateral wall of the orbit curving around the margin of the orbital rim deep to the temporalis. Posteriorly the bone is deficient in a number of areas with the cyst communicating with the middle cranial fossa with no evidence of extension into the intracranial. Intracranial dermoid cysts are benign lesions of embryologic origin that represent less than 0,6 % of all primary intracranial tumors 1,2. Dermoid cysts contain ectodermal derivatives - hair follicles, sweat glands, and sebaceous glands 1,3 This ultrasound case shows many of the typical features of an ovarian torsion. The ovary is distended with absent Doppler flow and some adjacent free fluid. The ovary also contains a 4 cm dermoid cyst with an echogenic Rokitansky nodule ('dermoid..

The MRI appearances are typical for an ovarian mass containing different tissue types including fat, calcification, and soft tissue, and therefore typical for an ovarian dermoid cyst. There were no clinical or imaging signs of ovarian torsion, an.. Dermoid cyst Radiology Case Radiopaedia . Dermoid cysts may be present at birth and can be found in the face, spinal cord, or skull. Dermoid cysts may also develop in the ovaries in women during the childbearing years. Dermoid cysts of the ovary, also known as benign or mature teratoma, are the focus of this article. Dermoid cysts may be single or can occur in both ovarie
