Cervical Epidural Hematoma That Induced Sudden Paraparesis After Cervical Spine Massage: Case Report and Literature Review.

BACKGROUND: Most people understand spinal manipulation therapy to be a safe procedure, and in many cases treatment is provided without a diagnosis if there is musculoskeletal pain. Cervical epidural hematoma occurs in extremely rare cases after cervical manipulation therapy. This study reports a case of epidural hematoma that occurred in the anterior spinal cord after cervical massage. CASE DESCRIPTION: A 38-year-old male patient was admitted to the emergency department for sudden weakness in the lower extremity after receiving a cervical spine massage. No fracture was found using cervical radiographs, and there were no particular findings on performing brain computed tomography or diffusion magnetic resonance imaging. However, using cervical magnetic resonance imaging, an acute epidural hematoma was observed in the anterior spinal cord from the C6 and C7 vertebrae to the T1 vertebra, compressing the spinal cord. There were no fractures or ligament injury. No surgical treatment was required as the patient showed spontaneous improvements in muscle strength and was discharged after just 1 week, following observation of the improvement in his symptoms. CONCLUSION: Although cervical epidural hematoma after cervical manipulation therapy is extremely rare, if suspected, a thorough examination must be performed in order to reduce the chances of serious neurologic sequelae.

Influence of lamina terminalis fenestration on the occurrence of the shunt-dependent hydrocephalus in anterior communicating artery aneurysmal subarachnoid hemorrhage.

Recently, it was reported that fenestration of the lamina terminalis (LT) may reduce the incidence of shunt-dependent hydrocephalus in aneurysmal subarachnoid hemorrhage (SAH). The authors investigated the efficacy of the LT opening on the incidence of shunt-dependent hydrocephalus in the ruptured anterior communicating artery (ACoA) aneurysms. The data of 71-ruptured ACoA aneurysm patients who underwent aneurysmal clipping in acute stage were reviewed retrospectively. Group I (n=36) included the patients with microsurgical fenestration of LT during surgery, Group II (n=35) consisted of patients in whom fenestration of LT was not feasible. The rate of shunt-dependent hydrocephalus was compared between two groups by logistic regression to control for confounding factors. Ventriculo-peritoneal shunts were performed after aneurysmal obliteration in 18 patients (25.4%). The conversion rates from acute hydrocephalus on admission to chronic hydrocephalus in each group were 29.6% (Group I) and 58.8% (Group II), respectively. However, there was no significant correlation between the microsurgical fenestration and the rate of occurrence of shunt-dependent hydrocephalus (p>0.05). Surgeons should carefully decide the concomitant use of LT fenestration during surgery for the ruptured ACoA aneurysms because of the microsurgical fenestration of LT can play a negative role in reducing the incidence of chronic hydrocephalus.
