The importance of ovarian teratoma as a cause of opsoclonus myoclonus ataxia syndrome (OMAS) and other paraneoplastic syndromes continues to be underestimated. A strong suspicion and appropriate diagnosis remain keys to successful outcome of paraneoplastic OMAS with ovarian teratoma. We report a 14-year-old girl with paraneoplastic OMAS in association with an ovarian teratoma who improved completely following resection of tumour as well as immunotherapy and review the literature briefly.

Purpose: Ovarian mature cystic teratoma (MCT) is the most common ovarian tumor, and only a small fraction undergoes malignant transformation. The most prevalent malignant type of the ovary is squamous cell carcinoma, followed by adenocarcinoma. However, ruptured ovarian mature cystic teratoma with adenocarcinoma transformation is extremely rare.

We report the case of a 24-year-old female with no significant medical history, who developed severe anxiety, memory deficits, and confusion over a two-week period. Neurological examination revealed cognitive dysfunction, asymmetric limb movements, and psychosis.

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis stands as the most prevalent form of autoimmune encephalitis, primarily affecting young patients and exhibiting a higher incidence among females. Patients frequently present with psychiatric symptoms or cognitive impairments such as speech disturbances, decreased level of consciousness, autonomic dysfunction, as well as seizures, dyskinesias, and catatonia due to overactivation of extrasynaptic NMDA receptors. To date, there is no gold standard for the diagnosis of catatonia; however, a few rating scales exist to measure this phenomenon, with the Bush Francis Catatonia Rating Scale being the most commonly used due to its validity, reliability, and ease of application.

Mature cystic teratoma (MCT) is the most common germ cell tumor of the ovary, comprising 20% of all ovarian neoplasms. Malignant transformation (MT) is an uncommon complication and occurs in approximately 1-3% of all MCTs. The most common histological type of MT is squamous cell carcinoma.

Purpose: The O-RADS malignancy risk stratification of typical ovarian dermoid cysts by using a 10 cm threshold is based on expert consensus rather than analysis of objective clinical data. This comprehensive scoping review consolidated all currently available studies evaluating typical benign ovarian dermoid cyst size and risk for malignant transformation.
Methods: A systematic review of MEDLINE, Embase, Scopus and the Cochrane library was performed from inception to January 14, 2024, using PRISMA-ScR guidelines.
