Lactococcus lactis cremoris is one of the gram positive cocci, not known to be pathogenic in humans. We report a case of brain abscess due to lactococcus lactis in an adolescent. An 18-year male with congenitally corrected transposition of great arteries and dextrocardia was admitted with fever, headache and right-sided numbness. Magnetic resonance imaging revealed a well circumscribed irregular heterogeneous abnormal signal intensity lesion in left temporo-parietal lobe having central area of diffusion restriction and peripheral wall enhancement on post-contrast images. He underwent mini-craniotomy for abscess drainage. Pus culture revealed growth of lactococcus lactis. He was treated with ceftriaxone and remained disability-free on six month follow-up. To our knowledge, this is one of the few reports of brain abscess caused by lactococcus lactis. Key Words: Brain abscess, Lactococcus lactis, Adolescent.
