Ipsilateral brain atrophy is rare in neoplastic lesions of the brain, but it has been reported in patients with a thalamic tumor. We report a Chinese boy who presented with a right focal motor
seizure
and right side weakness at the age of six and half years when an electroencephalogram (EEG) showed focal epileptic discharges over the left hemisphere, but computed tomography (CT) of the brain failed to reveal a definite mass lesion. The weakness became gradually worse. On admission at age 8, follow-up CT scan revealed a huge tumor (5 x 5 x 7 cm) compressing the third and lateral ventricles with mixed densities in the left thalamus and centrum semiovale. The scan after contrast infusion showed a marked enhancement of the tumor. Instead of peri-mass edema surrounding the tumor, the overlying cerebral tissue showed atrophy of the ipsilateral cortical layer. He received subtotal resection of the tumor. The pathology proved to be
germinoma
. A test of tumor markers revealed a high human chorionic gonadotrophin level in the blood and cerebrospinal fluid. A short course of radiotherapy and chemotherapy was given after surgery. He has been well for the past two years.

Brain tumors are, after leukemias, the most frequent fatal neoplasms of infancy. The clinical features and symptoms are often markedly different from those observed in the adult forms, according to the peculiar anatomy and behaviour of the child. Persistent headache, vomiting, astenia , behavioral alterations may be the precocious findings. Later, some more specific and suggestive signs such as strabismus, dyplopia , fast head size increase, funduscopic alterations, ataxia, paresis and nystagmus may be observed. On their appearance a prompt diagnostic work-up should be performed. The tumors of the posterior fossa (cerebellar astrocytoma and medulloblastoma, brainstem glyoma , hependimoma in decreasing order of frequency) generally cause precocious symptoms because of the small dimension of the subtentorial space; the presence in this region of several fundamental nuclei and pathways may explain how also small tumors may cause severe deficits. Supratentorial tumors (astrocytoma, malignant glyoma , hependimoma , craniofaringioma ) often show a more prolonged latency and may begin with signs of endocranial hypertension,
seizures
, or sometimes with hormonal troubles according to the involved anatomic structures. Hypothalamic astrocytoma is responsible of an extreme weight loss as far as to a cachetic status, due to the hyperincretion of GH. Finally, plexus papilloma, dermoid, optic nerve glyoma , oligodendroglyoma ,
germinoma
, teratoma are responsible of a small number of child brain tumors, with different localization and symptomatology.

Twenty year old boy was admitted because of a recent history of generalized
seizures
and papilledema. Neurological examination was essentially negative except papilledema in the both optic fundi. A history of polydipsia or polyuria was not obtained. CT scan showed bifrontal cystic lesions and cyst walls were partly enhanced. Midline frontal nodules around the foramen of Monro were also revealed by enhancement. Operation was performed and biopsy specimen showed typical histology of
germinoma
with a small focus of squamous epithels. Postoperatively, the patient's urinary output increased temporalily up to 5,000 ml per day under steroid administration. Shortly after irradiation, cysts decreased in size and all enhanced lesions disappeared completely. The patient is fully working without disturbance one and half year after the onset. Close relationship of
germinoma
and teratoma was briefly reviewed in literature.

It is well known that Down's syndrome is sometimes associated with leukemia. However, there have been only a few case reports of a relationship between Down's syndrome and brain tumors. We report 2 cases with histological diagnoses of
germinoma
. The 1st case was a 10-year-old boy with Down's syndrome complaining of
seizure
and left hemiparesis. Computed tomographic (CT) scan and magnetic resonance imaging (MRI) showed a mass lesion in the right basal ganglia and thalamus. Histological examination indicated two cell pattern germinomas. The 2nd case was a 20-year-old man with Down's syndrome complaining of headache and vomiting. CT scan and MRI showed a pineal region tumor with marked hydrocephalus. Surgical specimens showed typical
germinoma
. Only 13 cases of brain tumors associated with Down's syndrome have been reported. A higher incidence of germ cell tumors seems to be related to chromosomal abnormalities.

A 6 year-old boy presented with peripheral precocious puberty and was diagnosed as having simple virilizing 21-hydroxylase deficiency based on clinical features and elevated 17-hydroxyprogesterone levels on ACTH stimulation. He was managed with glucocorticoids and mineralocorticoids. Two years later he presented with features of CNS involvement in the form of
seizures
and raised intracranial pressure with rapid progression of puberty. Contrast enhanced CT scan of brain showed an intraventricular tumor with cerebrospinal fluid cytology suggestive of
germinoma
. Serum and CSF levels of human chorionic gonadotropin (hCG) and alphafetoprotein (AFP) were elevated, confirming the diagnosis of
germinoma
.

The authors present a case of
germinoma
that was initially found in the pineal region and recurred 15 years later in the intramedullary cervical spinal cord after intensive chemo- and radiotherapy and diagnosis of complete remission. This 28-year-old man initially presented with
seizures
. Hydrocephalus and a pineal tumor were found on radiological examination, and partial resection of the tumor was performed. Histological diagnosis showed a pure
germinoma
. Following surgery, the patient received a combination of chemo- and radiotherapy, and a complete remission was shown. However, after 15 years of follow-up, he presented with gait disturbances. Spinal MRI showed an intramedullary mass lesion in the cervical spinal cord. The cervical lesion was biopsied, and histological examination again revealed a pure
germinoma
. With germinomas, the possibility of a drop metastasis from an intracranial lesion to the spinal cord must be considered during follow-up. However, in the present case, analysis of a CSF sample showed no abnormalities as in previously published cases. In recent years, multidisciplinary treatments have demonstrated good event-free survival rates in cases of pure germinomas, but long-term outcomes over the decades are not fully known. Continual follow-up of such cases is recommended even after complete remission has been achieved.

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 clinical symptoms, detection of tumor markers, such as alpha fetoprotein (AFP) and the beta subunit of human chorionic gonadotropin (beta-hCG) in blood and cerebrospinal fluid (CSF), magnetic resonance imaging (MRI) of the brain and spinal cord, CSF cytology and histology. The diagnosis of a secreting germ cell tumor, i.e. a non-
germinoma
, can be made by the determination of AFP and hCG as tumor markers.
Germinomas
are radiosensitive but are equally as sensitive to chemotherapy. Teratomas of the CNS are mostly diagnosed in newborns and infants. The most decisive role in the treatment of teratomas is played by as complete a resection as possible. Chemotherapy and irradiation play a subordinate role.Embryonal tumors, which constitute approximately 15-20% of CNS tumors, include medulloblastomas, primitive neuroectodermal tumors (PNET) of the CNS and the atypical teratoid rhabdoid tumor of the CNS. Medulloblastoma is the most common malignant brain tumor in childhood and adolescence. The incidence peak is the fifth year of life with a male predisposition in a ratio of 1.5:1. Medulloblastomas constitute 12-25% of all pediatric CNS tumors and 30-40% of pediatric tumors of the posterior cranial fossa. At the time of diagnosis evidence of dissemination in the CSF cavity is found in approximately 40% of patients. The extreme cell density makes medulloblastomas hyperdense in computed tomography (CT) and can therefore be differentiated from hypodense astrocytomas. The PNETs are histologically related to medulloblastomas, pineoblastomas, atypical teratoid rhabdoid tumors and peripheral neuroblastomas. They are relatively rare in children constituting less than 5% of supratentorial neoplasms. Patients are mostly clinically conspicuous due to macrocephalus and signs of brain pressure and/or
seizures
. In native CT the solid components of PNETs show a hyperdensity compared to the surrounding brain parenchyma probably due to the high cell density. Cysts and calcification are often detectable. The survival rate of children with CNS tumors has continuously increased in recent years. When corresponding clinical symptoms appear, such as headache, nausea or vomiting when fasting, all of which are evidence of increased intracranial pressure, MRI should be carried out as quickly as possible. Children should be treated in centers with departments of pediatric oncology and hematology and within the framework of studies.

Germinoma
is rare in peripheral lobar locations in the brain, with only 10 cases of primary frontal lobe
germinoma
having been reported in the previous literature. Epilepsy is a rare manifestation of germinomas. We describe an unusual case of a primary frontal
germinoma
in a 21-year-old man who presented with epilepsy. A presumptive diagnosis of abscess or cystic glioma was made, and then, we performed microsurgery under magnetic resonance imaging (MRI) neuronavigation guidance. Postoperative histopathologic examination identified the tumour as a rare
germinoma
. Subsequently, adjuvant radiotherapy and chemotherapy programmes were adopted in the present case, and there were no recurrence and postoperative
seizure
symptoms observed in the follow-up 6 months after operation.
