Spontaneous disappearance of a middle cranial fossa arachnoid cyst after suppurative meningitis.
BACKGROUND
Spontaneous disappearance of an arachnoid cyst is very rare, particularly after suppurative meningitis.


METHODS
A 2-month-old boy with a high fever was diagnosed with suppurative meningitis by cerebrospinal fluid examination. Computed tomography disclosed a large arachnoid cyst in the left middle cranial fossa. Two months later, the meningitis was cured. The arachnoid cyst disappeared with long-term antibiotic therapy alone.


CONCLUSIONS
Although an infected arachnoid cyst may disappear with antibiotic treatment alone, careful observation and individualized patient management are essential.
