teratoma

There are no pathognomonic features of a retroperitoneal teratoma on plain radiographs, although they may demonstrate calcification.

In view of the presence of an isolated intranasal mass, the differential diagnoses considered at the time of presentation were congenital midline nasal mass (e.g., nasal glioma) and nasal tumor (e.g., nasal chondromesenchymal hamartoma, or nasal teratoma).

Rupture accounts for 1%-2% of all complications associated with teratoma. Teratoma rupture can be classified as acute or chronic type.

The primitive cardiac teratoma is extremely rare; the cases reported in the literature are limited to a dozen cases and they are approximatively 1-5% of all pediatric neoplasms [4, 5].

All the cases (7 cases) of benign cystic teratoma were correctly diagnosed based on their characteristic ultrasound features which included:

Dalmau identified anti-hippocampal and prefrontal nerve cell membrane NMDAR antibodies in this patient population and first named this syndrome.[1] Here, we describe a case of one patient with anti-NMDAR encephalitis accompanied by ovarian teratoma.

Se definio como "gestacion multiple de dificil diagnostico" aquella en la que el examen del (de los) feto(s) planteo uno de los diagnosticos diferenciales expuestos (feto macerado/evanescente, gemelo siames, fetus in fetu, feto acardico, teratoma congenito).

Dr Al Agha cited particularly the Sacrococcygeal Teratoma, an unusual tumour that, in the newborn, is located at the base of the tailbone (coccyx).

Ultrasound can detect an intratesticular multicystic mass, and the normal testicular parenchyma can be evaluated when the clinical diagnosis suggests a cystic teratoma (1, 5-6).
