A 13-year-old girl presented with an exceedingly rare case of primary yolk sac tumor located within the lateral ventricle, manifesting as headache, nausea, and diplopia. Magnetic resonance imaging revealed a 4-cm-diameter solid enhanced mass within the left inferior horn of the lateral ventricle.
A rare case of yolk sac tumor in the cerebellar vermis is reported. A 2-year-old boy developed headaches, vomiting, and an unsteady gait. Later a tumor was demonstrated in the medial part of the cerebellum by gadolinium-enhanced magnetic resonance imaging (MRI). The tumor was totally removed, and
BACKGROUND
Yolk sac tumors represent only 5%-7% of intracranial germ cell tumors, which comprise about 1% of all primary brain tumors in adults. Literature data about nonspecific imaging characteristics of these tumors are scant. We presented magnetic resonance imaging findings with
The nongerminomatous germ cell tumor occurring in the fourth ventricle is extremely rare. A 9-year-old boy presented with symptoms of obvious headache, projectile vomiting, diplopia and motor weakness. MRI scanning revealed lesions occupying the fourth ventricle, with dual-lateral ventricle
A 15-year-old male was admitted because of diplopia and persistent headache. Postcontrast computed tomography (CT) revealed a homogeneously enhanced large mass, 3 x 4 cm in size, in the pineal region and moderate obstructive hydrocephalus. A right ventriculoperitoneal shunt was installed. At that
The authors described a case of primary intracranial endodermal sinus tumor (EST), and presented a review of 24 reported cases. From the middle of December 1981, this 15-year-old boy experienced progressive diplopia. At the other hospital, partial removal of the intrasellar tumor was performed by a
A case, a 18-year-old male, of an endodermal sinus tumor (yolk sac tumor) in the fourth ventricle, was reported. The patient had a month history of headache, vomiting and gait disturbance prior to the hospitalization, when he admitted to our service he was in lethargic condition with left cerebellar
Intracranial nongerminomatous germ cell tumors (NGGCTs) in unusual locations are extremely rare. Here, we report a case of a yolk sac tumor in the frontal lobe in a middle-aged patient. A 42-year-old man was admitted to our hospital for headache and nausea. Magnetic resonance imaging (MRI) showed an
A case of primary intracranial yolk sac tumor, the first known case growing in the frontal lobe, is compared with similar cases of suprasellar region. The case, 18-year-old female, suffered from headache, vomiting and visual disturbance for one month prior to the hospitalization. Plain CT scan
The primary intracranial endodermal sinus tumor (EST) is regarded as a rare histological subtype that is often associated with components of other germ cell tumors, and there are no reports on the onset of intracranial ESTs after growth hormone (GH) replacement therapy. The authors report an
Endodermal sinus tumors are rare malignant germ cell tumors that usually originate from the gonads and are rarely observed extragonadally. Pure primary endodermal sinus tumors of the cerebellar hemisphere are extremely rare and patients diagnosed with the disease often have a poor prognosis. The
A 45-year-old female patient presented with symptoms of polydipsia and polyuria, menopause, headache, gait disturbance and deteriorated mental state. Brain magnetic resonance imaging (MRI) showed an irregular mass in the anterior third ventricle. The tumor was excised using a transfrontal approach
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 resolution of a pineal germinoma.
METHODS
A 21-year-old man who presented with headache and diplopia was admitted to our hospital.
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
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
