Dec 25, 2024 · Dermoid cysts are cysts that contain skin elements including squamous epithelium and dermal appendages (adnexa), such as sebaceous and sweat glands and hair. They are discussed separately according to anatomic location:

Mar 3, 2025 · Ovarian dermoid cyst and mature cystic ovarian teratoma are terms often used interchangeably to refer to the most common ovarian neoplasm. These slow-growing tumors contain elements from multiple germ cell layers and can be assessed with ultrasound or MRI.

Aug 15, 2024 · Epidermal inclusion cysts or epidermal cysts are common cutaneous lesions that represent proliferation of squamous epithelium within a confined space in the dermis or subdermis.

Annotated ultrasound images showing the Rokitansky nodule, echogenic mesh (hair), dense shadowing foci (tip of the iceberg) and focus of possible tooth/ossification which are the characteristic features of an ovarian dermoid cyst.

Dec 20, 2024 · The Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS US) forms the ultrasound component of the Ovarian-Adnexal Reporting and Data System (O-RADS). This system aims to ensure that there are uniform unambiguous sonographic evaluations of ovarian or other adnexal lesions, accurately assigning each lesion to a risk category of ...

Case Discussion This lesion was discovered incidentally during a CT examination and it was clinically palpable during the ultrasound examination. Radiological findings are suggestive of a subgaleal congenital dermoid inclusion cyst.

On ultrasound, they usually appear as an-echoic well-defined masses with posterior acoustic enhancement, while on CT scan, they manifest as a well-defined, unilocular, low-attenuating mass lesion.

Jun 30, 2024 · The floating balls sign refers to the appearance of multiple mobile globules/spherules of solid, usually fatty, tissue within an adnexal cyst. It is pathognomonic for ovarian mature cystic teratoma 1,2.

Aug 5, 2023 · Intracranial dermoid cysts are uncommon lesions with characteristic imaging appearances. Dermoid cysts can be thought of as along the spectrum: from epidermoid cysts at one end (containing only desquamated squamous epithelium) and teratomas at the other (containing essentially any kind of tissue from all three embryonic tissue layers).

Mar 3, 2025 · Ovarian dermoid cyst and mature cystic ovarian teratoma are terms often used interchangeably to refer to the most common ovarian neoplasm. These slow-growing tumours contain elements from multiple germ cell layers and can be assessed with ultrasound or MRI.
