Enterobacter sakazakii was described in 1980 as a new member of the Enterobacteriaceae family.[1] Infants with meningitis due to E. sakazakii were generally less than 1 week old.[2],[3] The first signs of sepsis appear between the 4th and 8th day of life. The infants tend to be of greater gestational age and birth weight.[3] Reviewing the literature between 1958 to 2005, Bowen and Braden[3] reported seven cases of neonatal brain abscess due to E. sakazakii.[4]

Here we report the 8th case. A 6-day-old female child who was delivered normally with a birth weight of 3.2 kg, presented with altered sensorium and high-grade fever of 3 days. Examination revealed a hypoactive child with tense anterior fontanelle. Blood and cerebrospinal fluid (CSF) culture showed the growth of  E.sakazakii Scientific Name Search . Cranial ultrasonography revealed multiple hypoechoic areas within the frontal lobes. During her treatment, she developed repeated secondary generalized seizures. So, she was put on a ventilator.

Computerized tomography (CT) contrast brain scan revealed a non-enhancing diffuse hypodense region with mass effect in the left frontoparietal lobes. On the right side, there was a similar hypodense region without mass effect. Meninges and ventricular walls showed minimal enhancement suggestive of meningitis and ventriculitis. A diagnosis of bilateral frontal focal cerebritis with mass effect was considered. She was initially treated conservatively with parenteral antibiotic meropenem. The follow-up contrast CT brain performed at 3 weeks, showed brain abscesses. The left frontoparietal abscess measured 77 mm × 53 mm × 78 mm. There was a second abscess in the left parieto-occipital lobe which measured 19 mm × 37 mm × 44 mm. A third abscess was present on the right frontal lobe that measured 51 mm × 18 mm × 71 mm [Figure 1]. Repeated serial aspirations were performed on both sides. The culture of the pus revealed E. sakazakii. She was gradually weaned off the ventilator.

Serial imaging scans [Figure 2] showed a progressive decrease in the size of the brain abscesses. Antibiotic meropenem was given intravenously for 6 weeks followed by ciprofloxacin orally for 4 weeks. A follow-up CT brain showed evidence of multiloculated hydrocephalus [Figure 3]. Ventriculo-peritoneal shunt surgery was performed for the hydrocephalus. At the end of 2 years, the child was still retarded. We report this case to highlight the occurrence of E. sakazakii as a cause of brain abscess in the neonate.
