“…22,23 We observed a significantly higher susceptibility effect in oligodendrogliomas with 1p/19q deletions. Calcification and tumor-associated hemorrhage are commonly seen in oligodendrogliomas, 43 which may have contributed to the susceptibility effect in our study. Previous studies 22,23 have also reported that oligodendrogliomas harboring 1p/19q loss usually demonstrate an indistinct border, whereas a sharp border is a characteristic of those with intact 1p/19q alleles.…”

“…12 Although the likelihood of an OD is high for a calcified supratentorial intraparenchymal tumor, 19,20 the differential diagnosis of a calcified intra-axial intracranial mass includes other tumors as well, including ependymomas and low-grade astrocytomas. Therefore, the final diagnosis, while limited, is always made on histopathology.…”

“…Other presenting symptoms include headache, mental status changes, nausea, vomiting, vertigo, visual complaints and/ or focal weakness [2]. On diagnostic imaging, ODG's appear as mass lesions with fairly well defined margins, usually located in the cortex and subcortical white matter [5]. Calcifications are common and are seen in 90% of ODG's on CT scans [3].…”

Introduction: Oligodendroglioma's (ODG) are primary glial brain tumors that are divided into classical and anaplastic ODG's. Common pathologies encountered in the corpus callosum include primary central nervous system lymphomas and glioblastoma. Corpus callosal ODG is a rare entity. Case Report: A 54 year old male presented with headache since 6 months and weakness of right upper and lower limbs since 4 months. Radiological imaging was suggestive of a heterogeneous minimally enhancing mass arising from the corpus callosum and extending bilaterally into the frontal lobes (left more than right). Left frontal craniotomy and tumor decompression was done. Final histopathological report was "oligodendroglioma grade II but likely to behave in an aggressive manner". Patient received adjuvant chemo-radiation and on his latest follow up two years post-surgery, radiological imaging showed only gliotic changes in the brain. Conclusion: Corpus callosal oligodendroglioma is a rare entity. The treatment for anaplastic and aggressive ODG's should include gross total resection (wherever possible) or tumor decompression followed by adjuvant chemo-radiation.
