 Greetings to everyone. My name is Dr. Vishnu Hoja. I am second year post graduate student of NRS Medical College. My topic for paper presentation is CNS Neoplasm Ganglio Gayama, under guidance of Dr. Amchandra Bhadra, associate professor of NRS Medical College, Kolkata. CNS Neoplasm Ganglio Gayama. Introduction. Ganglio Gayamas are rare tumors of central nervous system. Ganglio Gayamas most frequently affect children and young adults with slight male preponderance. It accounts almost 1% of all CNS Neoplasms. Ganglio Gayamas can occur anywhere in CNS, but they are most commonly found in temporal lobe after 85%. Often associated with seizure, Ganglio Gayamas are most common tumor related to temporal lobe epilepsy. Herein, we report a case of Ganglio Gayama, a 12 years old boy, who was suffering from seizure, decorticate posture and unconsciousness. M. Magnetic resonance imaging or MRI as the imaging modality with different sequence of MRI to diagnose Ganglio Gayama of temporal lobe. After 12 years of old boy, who was suffering from seizure, disorder, decorticate posture and unconsciousness. Method a case report, method of data collection MRI, study tools, GE signal, HDE, 1.5 Tesla MRI machine. Case presentation, a 12 years old boy presented to neurology OPD with complaint of frequent seizures episodes followed by unconsciousness. A decorticate posture occurs before unconsciousness. Total episode of this incident lasts for 10 to 15 minutes and it occurs at least 1 to 2 times per week. The boy was suffering from the disease for last 2 years. After OPD examination, the patient was then admitted to neuro surgery ward various and then the various anti epileptic medication had been started and various laboratory tests, electroencephalography and MRI of brain were done. Laboratory test results were within normal range. MRI revealed heterogeneous lesion in right temporal region with right temporal point prominence. Possibility of Ganglio Gayama. Irregular polymorphic, 2 to 5 hours lateralized activity type 2A noted in electroencephalogram. Suggestive of seizures originating from temporal neocortex. The patient then underwent temporal lobe resection surgery, grabbed the right side and post surgical period was uneventful and the condition of the boy was gradually improved. There was no episode of seizure or unconsciousness for last 6 months after the surgery. MRI findings. T2-weighted FSC and flare images showing heterogeneous lesion in right temporal region with right temporal point is prominent. Diffusion imaging is not showing any abnormal signals. Rest of the cerebral pancrema and ventricular systems is normal. No midline shift is seen. Pituitary fossa appears normal. Cerebellum and brain stem appears normal. Normal flow void signals is seen in major cerebral blood vessels. Impression. Heterogeneous lesions is seen in right temporal region with right temporal point is prominent. Possibility of Ganglio Gayama, cortical or cortical dysplasia or subacute in fact may be there. MRI images. This arrow indicates, arrow marks indicates the hyper intense signal in T1-weighted MRI images. Suggesting of tumor in right temporal lobe. Here also the T1-weighted flare images which indicates the hyper intense signal in temporal lobe. Then the T2-weighted FSC images which causes heterogeneous lesions and the prominent temporal lobe. T2-weighted FSC images suggesting of tumor and the T2-weighted flare images which also indicating the tumor, the hyper intense or heterogeneous hyper intense area in temporal lobe and which is suggesting of tumor. Here in cytal plane there are T2-weighted cytal images. Here also we can locate a tumor. DWI images not showing any abnormal signal. Diagnosis, the biopsy specimen taken from the resected tissue, all the section contain tumor which is moderately cellular and the glial cells are elongated which contains angulated and hyperchromatic nuclei. Some fascicular arrangement is noted and scattered dysmorphic neurons are seen. Intermixed with glial cells, they are haphazardly arranged and some cells are bionucleated with nucleomegaly. No microhospular proliferation or necrosis noted, no oligodendroglial component noted. The adjacent cortex shows cortical dysplasia with disorganized neurons but no balloon cells. Neurofenotyping done which are showing positivity to various neuronal markers. The synaptophycin positive is positive, GFF positive neurofilament protein positive, chromogranin A positive, neon N positive indicating both glial and neuronal differentiation. IDH1 and MGMT are negative and the tropoisomerase index is 1 to 2%. ERTX shows no loss of staining or non-mutated. The features appear to show low-grade leonural tumor consistent with ganglion glioma. Final diagnosis, low-grade leonural tumor consistent with a ganglion glioma WHO grade 1. Discussion, ganglion gliomas are low-grade tumor of primary central nervous system. Ganglion gliomas are composed of glial and neuroepithelial elephants. Approximately they consist 1% of all intracranial tumor. They are more commonly appears in children and young adults. Temporal lobe is the most common location for these tumors. Seizures is the most important symptoms of this tumor. Surgical excision significantly improves the patient's condition. In our case MRI plays important role into evaluations of ganglion glioma of bright temporal lobe of the young boy. MRI shows exact location and lesion more precisely. The extent of the lesion and location help to diagnose the type of lesion. MRI is preferred modality because it is free from any ionizing radiation. Different imaging sequences of MRI help to diagnose the tumor. T1-weighted images shows lesion hyper intense where the T2-weighted FSC and flare images shows the lesion is hyper intense. The lesion is solid type without any cystic component and lesion hydrogenously enhance. In T2-weighted FSC and flare images prominent in flare images with prominent bright temporal harm. In conclusion MRI can be lead point for diagnosis of ganglion glioma of CNS. With the help of clinical history easy findings of the patient. The actual type of neoplasm can only be confirmed by histopathological examinations with immunophenotyping and immunophenotyping of rejected tissue. These are the references.
