OBJECTIVE
Primary intracranial germinomas (PIGs) are rare malignant brain tumors that represent approximately 0.2% to 1.7% of all primary intracranial tumors. PIGs have infrequent, but there is a possibility of spinal cord metastases. In this study, clinical outcomes of five consecutive PIGs have
Germinoma accounts for two-thirds of germ cell tumors and about 40% of all pineal region neoplasms. This case illustrates an unusual manifestation of metatastic germinoma with spread to ventricles and meninges without a pineal mass. A 24-year-old man presented with nausea, vertigo, and left facial
Intracranial mature teratomas have good prognoses and are usually treated by total tumor resection. We report a rare case of a germinoma that occurred 11 years after total removal of a pineal mature teratoma. A 5-year-old boy presented with headache and nausea and was diagnosed with a pineal tumor
OBJECTIVE
To analyse the clinical characteristics of intracranial germinoma.
METHODS
Retrospective analysis was applied to study the clinical characteristics of 26 intracranial germ cell tumor patients admitted to our hospital during 1991-2003. The clinical, biochemical and imaging profiles
A 23 year-old patient was referred to the endocrine outpatient clinic with the suspicion of diabetes insipidus as he complained of nycturia and polydipsia since 2-3 months. Further he presented with nausea, vomiting, loss of appetite, rapid weight loss, diffuse body pain and fatigue. No headache,
The recurrence or metastasis of intracranial pure germinomas as germ cell tumours of different histological types has rarely been reported. The present report concerns the first case in the literature of intracranial recurrence of a germinoma transformed into a choriocarcinoma. A 17-year-old man
Germinoma is the most common type of intracranial germ cell tumors (GCTs). Pineal gland and suprasellar region are the most frequent sites of central nervous system (CNS) involvement. Intracranial masses caused by Langerhans cell histiocytosis (LCH) mimics features of CNS GCTs. LCH frequently
OBJECTIVE
Despite lymphocytic or autoimmune infundibuloneurohypophysitis (INH) is an increasingly recognized aetiology in children with central diabetes insipidus (CDI); clinical data on epidemiology (clinical evolution, predisposing factors, complications), diagnosis and management of this entity
A 17-year-old male patient presented to the clinic with a headache, nausea, and vomiting. Magnetic resonance imaging demonstrated a fat-containing and -enhancing heterogeneous tumor in the third ventricle, and fat droplets within the ventricles and the subarachnoid space. Obstructive hydrocephalus
BACKGROUND
Proton beam therapy (PBT) for pediatric CNS malignancies may reduce late toxicity, but acute toxicity is not well defined. We examined acute toxicity for children with CNS malignancies treated with PBT.
METHODS
We conducted a retrospective review of 48 children with malignant brain tumors
Germ cell tumors, which constitute approximately 3-5% of tumors of the central nervous system (CNS), can be subdivided into germinomas, embryonal carcinomas, yolk sac tumors, choriocarcinomas, teratomas and mixed germ cell tumors. The diagnosis of intracranial germ cell tumor is based on the
BACKGROUND
Primary intracranial germ cell tumors represent a rare category of neoplasms, which occur in children and young adults. The WHO classification divides intracranial tumors into germinomas and non-germinomas. The most frequent locality of these tumors is pineal and suprasellar region.
An 18-year-old male was admitted with headache, nausea, and vomiting. Computed tomography (CT) revealed an enhanced tumor of the pineal region and hydrocephalus. The tumor was partially resected via a parieto-occipital craniectomy. The histological diagnosis was germinoma. No serum tumor markers
A 3-year-old boy had a history of nausea and vomiting for 1 month. After two episodes of tonic cramp, he became drowsy and then semicomatous. Physical examination on admission revealed a dehydrated semicomatous boy with fixed, dilated pupils of equal size, horizontal nystagmus, and left hemiparesis
Desmoplastic myxoid tumor (DMT), SMARCB1 mutant is a recently proposed new entity that mainly occurs in the pineal region and has epigenetic features similar to those of atypical teratoid/rhabdoid tumors (AT/RT)-MYC and poorly differentiated chordomas. Herein, we present a new case of a 33-year-old
