Objective To analyze the clinical, pathological and MRI findings of intracranial ganglioglioma. Methods 25 patients with intracranial ganglioglioma confirmed by pathology in our hospital were selected as the research object. The location, quantity, signal characteristics of plain scan and enhanced scan and peritumoral edema were analyzed to explore the MRI imaging findings. Results In the 25 patients, there were 22 cases with epilepsy seizures, including 19 cases whose only clinical manifestation was epilepsy and 3 cases was absence seizures. There were 2 cases with cystic lesions, 10 cases with cystic solid ones and 13 cases solid ones. Patients with cystic lesions mainly showed low signal on T1WI while patients with solid ones mainly showed equal signal or slightly low signal and patients with cystic solid ones showed both two types of signals. Patients with cystic lesions mainly showed high signal on T2WI while patients with solid ones mainly showed equal signal or slightly high signal and patients with cystic solid ones showed both two types of signals. Enhanced scan showed there was no enhancement in patients with cystic or solid lesions and there was mild enhancement in patients with solid ones and obvious enhancement and mild enhancement in patients with cystic and solid ones. There were 1 case without edema, 15 cases with mild edema, 4 cases with moderate edema and 5 cases with severe edema. Conclusion The main manifestation of intracranial gangliogliomas is epilepsy seizure, which can be divided into cystic, cystic solid and solid of 3 types. Different types of patients have different MRI findings. Combined with pathological features, it can provide guidance for clinical diagnosis and treatment.
