We report the case of an eighteen-month-old child who suffered a tympanic membrane perforation caused by a digital thermometer. This injury led to a CSF leak. The patient was followed conservatively with no surgical intervention or prophylactic antibiotic therapy and developed pneumococcal meningitis 7 days later. He was then treated with Ceftriaxone for 12 days with full recovery, from a short and long term perspective. Issues concerning the management of CSF leak will be discussed along with review of the literature. This is the first report of post-traumatic meningitis as a result of mild trauma not involving maxillofacial or basilar fractures. The aim of our report is to raise awareness to this cause of meningitis and to stress the importance of immunizing against Streptococcal pneumoniae, a measure which may have prevented the sequelae in our case.
