We evaluated the efficacy of interstitial brachytherapy (IBT) using (125)Iodine ((125)I) seeds for treatment of papillary tumors of the pineal region. Between September 2003 and September 2010, four patients (M/F = 2/2; median age, 57.3 years; range 29.2-69.1 years) with papillary tumors of the
OBJECTIVE
Evaluation of results of the neurofiberscopic biopsy of tumors of the pineal region and posterior third ventricle.
METHODS
From 2001 to 2004, 23 patients (mean age, 30.6 yr) with tumors located in the pineal region or posterior third ventricle underwent neurofiberscopic biopsy with
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 report on a rare case of pineocytoma is presented. A 27-year-old woman visited our clinic because of a 3-month history of intermittent headaches and nausea. A CT scan revealed the presence of a marked obstructive hydrocephalus and mass without any contrast enhancement in the pineal region.
The 2007 World Health Organization classification of tumors of the central nervous system identified "pineal parenchymal tumor of intermediate differentiation" (PPTID) as a new pineal parenchymal neoplasm, located between pineocytoma and pineoblastoma as grade II or III. Because of the small number
A 9-year-old female suddenly developed headache and nausea. Computed tomography (CT) revealed pineal mass lesion and obstructive hydrocephalus. One week after the onset, hydrocephalus spontaneously resolved. Magnetic resonance imaging (MRI) revealed that the mass was a subacute hematoma and that
A 61-year-old woman had suffered from severe headache and nausea over 20 times during the last 43 years. An subarachnoid hemorrhage (SAH) was detected by spinal puncture in some other hospitals, but the source of hemorrhage remained unknown in spite of repeated angiography. At the age of 61, she was
The endoscopic approach has gained an increased popularity in recent years for the biopsy and, in selected cases, the removal of tumors of the posterior third ventricle and pineal region. The authors report their experience on a series of 20 patients discussing also the technical limitations and
BACKGROUND
Pineoblastoma is a rare malignant tumor of the pineal gland, which is more common in children.
METHODS
We retrospectively reviewed 18 cases of pineoblastoma in children (10 girls), including general, clinical, and therapeutic information, and factors affecting prognosis.
RESULTS
The
Primary intracranial rhabdomyosarcoma is quite rare, and its prognosis is poor compared with that for rhabdomyosarcoma in other organs. The authors present a case of pineal rhabdomyosarcoma successfully managed with multimodal therapy including surgery, chemotherapy, radiation, and high-dose
OBJECTIVE Pineal region tumors are a rare and heterogeneous group of lesions. The optimal therapeutic approach is currently a topic of controversy, particularly in light of the potential operative risks and complications. The potential beneficial effects of surgery have already been described, but
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
OBJECTIVE
To discuss the clinical presentation, pathological diagnosis, and surgical outcome for a series of 42 consecutive patients treated for lateral and third ventricular tumors.
METHODS
This is a retrospective series study conducted between 2001 and 2015 and included 42 patients (mean age: 25
BACKGROUND
Endoscopic procedure for pineal region tumors and associated hydrocephalus has been getting more standard. We applied high-definition flexible neuroendoscopic system to the initial management of primary pineal malignant B-cell lymphoma. Efficacy of this new technology as an initial
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
