Abstract

Rothia dentocariosa and Streptococcus intermedius are bacteria of the normal upper respiratory tract flora. To our knowledge, only three cases of a brain abscess due to Rothia dentocariosa have been reported. We present a 66-year-old man with a cerebellar abscess due to Rothia dentocariosa and Streptococcus intermedius. The patient had gradual worsening of dizziness with imbalance and binocular diplopia in the past 3 days prior to admission. Abnormal findings from the neurological examination were: horizontal and circular positional nystagmus on right and left gaze, torsional vertical nystagmus on downward gaze, skew deviation with slightly hypertropic right eye with cover-uncover correction, slightly smaller right palpebral fissure, mild right limb ataxia in the upper (more than the lower) limbs, dysdiadochokinesia in the left upper limb, and dysmetria in the right lower limb. A magnetic resonance imaging (MRI) scan showed a spherical lesion in the right cerebellar lobe and large surrounding oedema. On the third day of his admission, his temperature increased, he had nausea and a delusional episode. A repeat computed tomography (CT) brain scan showed an increase in the surrounding oedema. The patient underwent a unilateral suboccipital craniectomy and drainage of the lesion. Based on cultures, the diagnosis was an abscess due to Rothia dentocariosa and Streptococcus intermedius. No source of infection was found. After the operation and a course of intravenous antibiotics, the patient's symptoms gradually improved. In conclusion, this is a rare case of a cerebellar abscess due to Rothia dentocariosa and Streptococcus intermedius.
