A case report of rare location of ganglioglioma

Abstract

Abstract Background Gangliogliomas are rare tumors of the central nervous system. They can occur anywhere in the central nervous system but are most commonly located in the temporal lobe and are mainly found in children. Anaplastic ganglioglioma can result from either de novo or transformation of a pre-existing lesion. Case presentation We report a case of de novo anaplastic ganglioglioma in the parieto occipital region, which is a rare location. A 34-year-old lady presented with features of raised intracranial pressure (ICP) with right side hemiparesis. Contrast-enhanced magnetic resonance imaging (CEMRI) of the brain showed well-defined intense heterogenously enhancing solid cystic mass lesion 5.3 × 5.2 cm in the left parieto occipital region with mass effect and midline shift. Intraoperatively, a cystic mass lesion with reddish brown nodule was seen in the left occipital lobe. Complete tumor excision was done. Microscopic and IHC examination was suggestive of anaplastic ganglioglioma. The post-operative period was uneventful. The patient received 60-Gy radiotherapy with temozolamide as adjuvant therapy, and repeat imaging showed no tumor recurrence. Conclusion Anaplastic gangliogliomas are rare tumors with parieto occipital as rare location.
