The authors describe a case of a giant intracranial mature cystic teratoma in a 16-year-old girl presenting acutely with a severe headache, vomiting and a complex generalised seizure with a background history of intermittent headaches for 3 years. CT and MRI brain demonstrated a ruptured large
An 18-year-old man was admitted with a 1-month history of headache and disturbed visual acuity. Neurological examination revealed a visual field defect of bilateral inferotemporal areas. The endocrinological examination was normal. Magnetic resonance imaging (MRI) revealed a large cystic lesion in
A 31-year-old female was admitted with headache, memory disturbance, abnormal behavior, incontinence, confusion, complex partial seizures, decreased oxygen saturation and increased temperature. Anti-NMDAR antibodies were positive in serum and cerebrospinal fluid. Subsequently, a regimen of
OBJECTIVE
We report the extremely rare occurrence of a second germ cell tumor at a different site and with different histological types long after total removal of a mature pineal teratoma.
METHODS
A 10-year-old boy who presented with headache and vomiting was admitted to our hospital.
Intracranial teratomas represent a rare lesion accounting for 0.1%-0.7% of all intracranial tumors. Those in the fourth ventricle have rarely been reported. The present case is that of a 28-year-old man with occipital headache for two months. MRI examination revealed a well-defined extra-axial
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
Intracranial teratomas account for 0.5% of all intracranial tumours and 2-4% of intracranial tumours in children. However, in terms of tumours of the pineal area, the exact incidence is not ascertained. Although, it is noted that 50-60% of central nervous system (CNS) germ cell tumours
BACKGROUND
This report describes a Successful treatment of anti-NMDA receptor encephalitis with early teratoma removal and plasmapheresis.
UNASSIGNED
We present a 31-year-old Caucasian nulliparous patient who was admitted as an emergency with general illness status accompanied by holocranial
Intracranial teratomas are rare tumors that usually present during the second decade of life. Among intracranial teratomas, suprasellar germ cell tumors in particular are extremely rare. We present the case of an 18-year-old girl who underwent a successful endoscopic transnasal Immature teratoma (IMT) is normally treated by resection and adjuvant therapy. The present unusual case of recurrent germinoma occurred 21 years after total resection of pineal IMT. A 3-year-old boy presented with headache, disturbance of consciousness, and Parinaud's syndrome. Magnetic resonance
Mature pineal region teratomas differ from other pineal tumors in terms of their characteristic radiological appearance and their clinical outcome after gross total excision. Our aim is to share our clinical experience and treatment outcomes in pediatric patients with mature pineal Medulla oblongata teratomas are rare. The authors report 2 new cases of teratomas that occurred exclusively in the medulla oblongata. The first case was in a 9-year-old boy who presented with a 6-month history of neck pain and repeated paroxysmal vomiting. Based on preoperative radiographic
Intracranial mature teratoma is a rare lesion in adults. Despite several intracranial mature teratomas had been reported not to be located at the midline region, no one was found to be within cerebral falx. Herein, we reported a 37-year-old female patient with an intracranial mature teratoma
Malignant transformation of a mature intracranial teratoma into an adenocarcinoma is an extremely rare event and portends a poor prognosis. The clinical progression, radiographic changes, histopathology, and immunohistochemistry of these unique cases may provide clues as to this OBJECTIVE
Teratomas represent 0.5% of all intracranial tumors. These benign tumors have tissue representative of the three germinal layers: ectoderm, mesoderm, and endoderm. Most teratomas are midline tumors located predominantly in the sellar and pineal regions. Cavernous sinus location is very
