ABSTRACT
INTRODUCTION: Brain parenchymal infection with pyogenic bacteria is often responsible for the development of brain abscesses. Brain abscess begins as a localized area of cerebritis followed by purulent lesion surrounded by a fibrotic capsule. Several pathogens that are involved in its development includes Streptococcus spp., Staphylococci, Bacteroides, Enterobacteriaceae, Fusobacterium spp. and etc.
CASE REPORT: We are presenting a case of right frontal lobe abscess of brain mimicking brain tumor in a 25-year-old male patient. He presented with chief complaints of fever associated with headache for 7 days and seizure for 2 days. He also gave history of intermittent headaches for 1 month. Imaging studies revealed the presence of right frontal space occupying lesion exerting mass effect. He finally underwent right frontal craniectomy with excision of the lesion. Histopathological examination (HPE) confirmed the diagnosis of right frontal abscess and excluded neoplastic etiology. Gram stain showed presence of Gram-positive cocci and confirmed infective etiology.
CONCLUSION: Numerous non-neoplastic lesions can mimic brain tumors and brain abscess is one of them. A systematic approach and assessment of patient’s history help to provide clue to narrow the differential.
