A newborn with hemorrhagic meningoencephalitis due to Proteus mirabilis.

Neonatal meningoencephalitis is a severe condition for the developing brain of a newborn. Radiologic findings of necrosis and liquefaction due to hemorrhagic meningoencephalitis may be confused with brain abcess. In this article, we report a neonate having liquefaction necrosis due to hemorrhagic meningoencephalitis mimicing intracranial abscess due to Proteus mirabilis. We would like to describe the clinical course and evolution of brain imaging and emphasize the importance of the serial MR imaging (MRI).
