“…There is a controversy over the best treatment strategy for CG : tumor biopsy/partial resection with subsequent adjuvant therapy, versus an aggressive gross total tumor resection7911). Traditionally, the surgical route to remove CG is transcranial and includes transventricular, transcallosal, and translamina terminalis approaches.…”

Chordoid glioma of the third ventricle is a rare and challenging tumor to surgery because of its unique anatomical location and its close juxtaposition to the neurovascular structures and hypothalamus. The authors report a case of chordoid glioma of the third ventricle in a 43-year-old woman, who presented with headache and somnolence. The tumor was approached by endoscopic transnasal technique with a favorable result. Histopathologic examination disclosed a neoplastic tissue composed of eosinophilic epithelioid cells, mucinous, periodic acid Schiff-diastase positive, extracellular matrix, and scattered lymphoplasmacytic infiltrates. The best treatment option remains controversial. Customarily, the surgical route to remove chordoid glioma is transcranial; however, the undersurface of the optic chiasm and optic nerves preclude an adequate surgical visualization. In contrast, an expanded endoscopic transnasal approach provides a direct midline corridor to this region without any brain retraction.

“…It is typically a well-circumscribed, round or oval-shaped tumor, with greatest diameter in the craniocaudal direction. The tumor is hyperdense to the gray matter at CT, isointense at MRI T1-weighted sequences, and isointense to slightly hyperintense at MRI long-TR, with strong, uniform enhancement after contrast agent administration ( 1 , 2 , 4 - 6 ) . Cystic changes and necrosis may be present ( 2 , 5 , 7 ) .…”

Central nervous system germ cell tumors (GCTs) account for less than 5% of primary brain tumors in children and adolescents but continue to attract much attention. To the best of our knowledge, a primary pure and nonsecreting embryonal carcinoma of the anterior third ventricle has never been previously reported. A 15-year-old boy presented with signs of increased intracranial pressure for the past 2 weeks complicated by 2 episodes of generalized tonic-clonic seizures 1 day before admission. Neurological examination was normal, and funduscopic examination disclosed a grade II papilledema bilaterally. CT and MRI revealed a well-demarcated and enhancing mass within the anterior third ventricle associated with a left lateral ventricle hydrocephalus. There was no evidence of tumor within the pineal or suprasellar region, and systemic and cerebrospinal fluid evaluation demonstrated normal levels of α-fetoprotein and human chorionic gonadotropin. Radical surgery was advised, and total tumor resection was achieved via a transcallosal transforaminal approach. The postoperative course was uneventful, and the final histological diagnosis was a pure embryonal carcinoma. Further screening showed no other location, and adjunctive high-dose chemotherapy was administered. The patient has been symptom free with no clinical or radiological sign of progression at the most recent follow-up examination 2 years after surgery. Primary pure and nonsecreting embryonal carcinoma can develop within the anterior third ventricle and should be considered in the differential diagnosis of anterior third ventricular masses especially in young patients. Accurate identification, radical surgery and high-dose chemotherapy can result in better tumor control and improve the postoperative outcome.
