Spontaneous leak of cerebrospinal fluid (CSF) into the middle ear occurs rarely and can easily be missed, especially in adults. Although the presenting symptoms can be subtle, early suspicion and confirmatory imaging can establish the diagnosis. Most previously reported cases of spontaneous CSF leak into the middle ear occurred on the right side. We report a case of left-sided single-defect spontaneous leak.
