[Aseptic meningitis associated to mumps during an epidemic outbreak].

We report two cases of acute aseptic meningitis associated to mumps in middle-aged women, one pregnant. Both presented shortly after parotid gland enlargement. Neurological complications were suspected by headache, fever and meningeal signs and confirmed by CSF findings (mononuclear predominant pleocytosis) with negative results for alternative causes. Mumps were confirmed by positive IgM and IgG serology. Both patients were discharged with a favorable evolution and complete disappearance of symptoms. Cases were concurrent with a regional mumps outbreak.

Conclusions

Aseptic meningitis is a rare mumps-associated neurological complication. Its diagnostic can be achieved by precedent parotid enlargement, mononuclear pleocytosis in the CSF and positive IgM and IgG serology or viral detection by PCR in urine or salivary samples. This complication would be more probably observed during mumps outbreaks.
