ABSTRACT
BACKGROUND: Chronic subdural hematoma (CSDH) is a common intracranial hematoma. The number of patients who undergo anticoagulant therapy including a direct oral anticoagulant (DOAC) is expected to increase. Recently, idarucizumab, the antidote for dabigatran, which is a DOAC, has been developed. We successfully treated CSDH with dabigatran using emergency burr hole surgery and idarucizumab. CASE DESCRIPTION: A 79-year-old Japanese man severely hit his head and visited the emergency department. Computed tomography (CT) showed tiny traumatic acute subdural hematoma, for which he was admitted. At that time, atrial fibrillation was newly detected, for which dabigatran, having a specific antidote (idarucizumab), was chosen and started 2 weeks after the discharge. Two months after the trauma episode, he revisited the emergency department because of acute left upper and lower limb motor weakness. CT revealed a midline shifted CSDH. Considering rush course of motor weakness and shifted brain, we performed emergency surgery using an antidote for dabigatran, idarucizumab. He was discharged 5 days after surgery without any complications or excessive perioperative hemorrhage. CONCLUSION: Dabigatran should be used for atrial fibrillation detected after head trauma. Emergency surgery can be safely performed for CSDH with dabigatran using idarucizumab.

Cheiro-oral-pedal syndrome is characterized by specific sensory disturbance around the corner of the mouth, in the hand and in the foot on the same side. Lesions responsible for causing this syndrome vary. We report two cases of cheiro-oral-pedal syndrome due to midbrain and pontine hemorrhage, respectively. Pontine hemorrhage producing cheiro-oral-pedal syndrome has been reported in three cases, but this is the first case that midbrain hematoma exhibits this syndrome. Damage in the sensory pathway can cause cheiro-oral-pedal syndrome. Difference in the threshold may explain the specific sensory pattern in this syndrome. Cheiro-oral-pedal syndrome is caused by lacunar infarction in majority of the cases. However, it should be kept in mind that hematomas can cause cheiro-oral-pedal syndrome.

Metronidazole is widely used for chronic or refractory infection and has recently also been used for the treatment of Helicobacter pylori. The authors report the case of a Japanese patient presenting with reversible cerebellar lesions induced by prolonged administration of metronidazole for treatment of H pylori with magnetic resonance imaging findings. Although rare, prolonged and high-dose administration of metronidazole may induce cerebellar lesions. Increased awareness of this phenomenon is important, as these lesions are reversible with discontinuation of this drug.
