| Summary: | Introduction: Neurocysticercosis (NCC) is an infection of the central nervous system by the larval stage of pork tapeworm (Taenia solium/T. solium). Diagnosing NCC can be challenging, particularly among those who reside in areas with rare occurrence of NCC and atypical manifestation such as a solitary parenchymal lesion. We treated a patient whose initially was diagnosed with brain abcess and later, brain tumor, only finally revealed to be an NCC case. Case report: A 25-year old male suffered from multiple focal-to-bilateral tonic clonic seizures, was initially diagnosed as brain abscess. He was given antibiotics and anti-seizure medication but the seizure relapsed with a typical semiology. Physical examination demonstrated grade I papilledema, grade 4+ hemiparesis, and headache of vascular origin. Patient was suspected to have oligodendroglioma after underwent head MRI examination and subsequent tumor resection was performed. Pathological anatomy evaluation demonstrated multiple cystic segments containing larva of tapeworm, supporting a diagnosis of active NCC infection. After 14-day course of antheminthic treatment and resumed AED, patient was seizure-free and NCC was not found upon follow-up CT scan. Conclusion: NCC, with respect to clinical and radiological manifestations, can be protean. A high index of suspicion towards NCC should always be maintained, particularly among patients originated from endemic area. Appropriate treatment with anthelminthic may result in full disease resolution, thus precluding unnecessary invasive approach.
