Post-traumatic spinal hematoma in diffuse idiopathic skeletal hyperostosis (DISH).

OBJECTIVES: To determine the incidence of spinal hematoma and its relation to neurological deficit after trauma in patients with spinal ankylosis from diffuse idiopathic skeletal hyperostosis (DISH). MATERIALS AND METHODS: A retrospective review of 2256 urgent or emergency MRI referrals over a period of 8 years and nine months revealed 70 DISH patients who underwent CT and MRI scans of the spine. Spinal hematoma was the primary outcome. Additional variables were spinal cord impingement, spinal cord injury (SCI), trauma mechanism, fracture type, spinal canal narrowing, treatment type, and Frankel grades during injury, before and after treatment. Two trauma radiologists reviewed MRI scans blinded to initial reports. RESULTS: Of 70 post-traumatic patients (54 men, median age 73, IQR 66-81) with ankylosis of the spine from DISH, 34 (49%) had spinal epidural hematoma (SEH) and 3 (4%) had spinal subdural hematoma, 47 (67%) had spinal cord impingement, and 43 (61%) had SCI. Ground-level fall (69%) was the most common trauma mechanism. A transverse, AO classification type B spine fracture (39%) through the vertebral body was the most common injury type. Spinal canal narrowing (p < .001) correlated and spinal cord impingement (p = .004) associated with Frankel grade before treatment. Of 34 patients with SEH, one, treated conservatively, developed SCI. CONCLUSIONS: SEH is a common complication after low-energy trauma in patients with spinal ankylosis from DISH. SEH causing spinal cord impingement may progress to SCI if not treated by decompression. CLINICAL RELEVANCE STATEMENT: Low-energy trauma may cause unstable spinal fractures in patients with spinal ankylosis caused by DISH. The diagnosis of spinal cord impingement or injury requires MRI, especially for the exclusion of spinal hematoma requiring surgical evacuation. KEY POINTS: • Spinal epidural hematoma is a common complication in post-traumatic patients with spinal ankylosis from DISH. • Most fractures and associated spinal hematomas in patients with spinal ankylosis from DISH result from low-energy trauma. • Spinal hematoma can cause spinal cord impingement, which may lead to SCI if not treated by decompression.

Neck pain and absence of cranial nerve symptom are clues of cervical myelopathy mimicking stroke: Two case reports.

BACKGROUND: Cervical myelopathy is a potential stroke imitator, for which intravenous thrombolysis would be catastrophic. CASE SUMMARY: We herein present two cases of cervical myelopathy. The first patient presented with acute onset of right hemiparesis and urinary incontinence, and the second patient presented with sudden-onset right leg monoplegia. The initial diagnoses for both of them were ischemic stroke. However, both of them lacked cranial nerve symptom and suffered neck pain at the beginning of onset. Their cervical spinal cord lesions were finally confirmed by cervical computed tomography. A literature review showed that neck pain and absence of cranial nerve symptom are clues of cervical myelopathy. CONCLUSION: The current report and the review remind us to pay more attention to these two clues in suspected stroke patients, especially those within the thrombolytic time window.

Atypical evolution after dengue: extradural hematoma of vertebral canal level l4-l5 / Evolução atípica após dengue: formação de hematoma extradural do canal vertebral nível l4-l5 / Evolución atípica después del dengue: formación de hematoma extradural del canal vertebral nivel l4-l5

ABSTRACT The objective of this paper is to report a case of atypical evolution after a classic case of dengue confirmed by serology, in which the formation of an epidural hematoma with low back pain and radiculopathy was observed. The article is a qualitative and descriptive case report. Data were collected from the medical records of the hospital where the patient was treated. In conclusion, the diagnostic correlation of dengue with this rare condition was possible due to radiological comparisons before and after the formation of the extradural hematoma. Level of evidence V; Expert Opinion.

Lumbar neuraxial procedures in thrombocytopenic patients across populations: A systematic review and meta-analysis.

INTRODUCTION: There is currently no consensus regarding the minimum threshold platelet count to ensure safe neuraxial procedures. Numerous reports describe the safe performance of lumbar punctures in severely thrombocytopenic patients but reports of neuraxial anesthetic procedures in thrombocytopenic patients are limited. To date, the focus on specific populations in contemporary reviews has failed to include any actual hematoma cases. This systematic review aggregates reported lumbar neuraxial procedures from diverse thrombocytopenic populations to best elucidate the risk of spinal epidural hematoma. METHODS: MEDLINE, Embase, Cochrane, CINAHL databases were searched for articles about thrombocytopenic patients (<100,000 × 106/L) who received a lumbar neuraxial procedure (lumbar puncture; spinal, epidural, or combined spinal-epidural analgesia/anesthesia; epidural catheter removal), whether spinal epidural hematoma occurred. RESULTS: Of 4167 articles reviewed, 131 met inclusion criteria. 7476 lumbar neuraxial procedures were performed without and 33 procedures with spinal epidural hematoma. Within the platelet count ranges of 1-25,000 × 106/L, 26-50,000 × 106/L, 51-75,000 × 106/L, and 76-99,000 × 106/L there were 14, 6, 9, and 4 spinal epidural hematomas, respectively. An infection point and narrow confidence intervals were observed near 75,000 × 106/L or above, reflecting a low probability of spinal epidural hematoma in this sample. Of the 19 spinal epidural hematoma cases for which the onset of symptoms was reported, 18 (95%) were symptomatic within 48 h of the procedure. CONCLUSIONS: Spinal epidural hematoma in thrombocytopenic patients is rare. In this sample of patients, an inflection point and narrow confidence intervals are observed near a platelet count of 75,000 × 106/L or above, reflecting an estimated low spinal epidural hematoma event rate with more certainty given a larger sample size and inclusion of spinal epidural hematoma cases. Thrombocytopenic patients should be monitored, particularly in the first 48 h, and educated about symptoms concerning for spinal epidural hematoma.

How low did we go? A case report of unexpected thrombocytopenia.

We report the case of a normotensive 31-year-old parturient who received combined spinal-epidural analgesia for early labor, and who was then found to have an unexpectedly low platelet count (25 000/µL) with elevated liver enzymes, but without alterations in blood pressure.

Iatrogenic Spinal Epidural Hematoma in the Acute Postoperative Period.

BACKGROUND: Spinal epidural hematomas (SEHs) are a rare but serious complication associated with spinal surgery, with an incidence estimated to be as high as 3%. Patients present with back pain and neurologic symptoms, with a typical onset time of several hours to days following surgery. CASE REPORT: A 60-year-old female who underwent cervical spine surgery had negative intraoperative neuromonitoring and no apparent neurologic deficits of the upper extremities immediately postsurgery. On arrival in the postanesthesia care unit, the patient reported a loss of sensation in her lower extremities, prompting the anesthesiology resident to perform a focused neurologic examination. The patient demonstrated 0/5 motor strength in the lower extremities and total loss of sensation to touch and temperature up to the level of T10 bilaterally. She was returned to the operating room, and surgical exploration revealed a cervical SEH. Decompression yielded abrupt return of motor evoked potentials and improvement in somatosensory evoked potentials. CONCLUSION: As the primary clinician in the perioperative period, the anesthesiologist is ideally positioned to be the first to detect any deterioration in a patient's condition. Anesthesiologists should be cognizant of the potential for acute presentation of SEH so that it can be considered in the differential diagnosis.

Neuraxial block for delivery among women with low platelet counts: a retrospective analysis.

BACKGROUND: Laboring women with low platelet counts may be denied neuraxial block due to concerns about causing a spinal-epidural hematoma. AIMS: To assess the anesthetic management, complications and outcome variables of women with low platelet counts, and to expand the existing data regarding the safety of neuraxial blocks in this patient population. METHODS: This is a retrospective analysis of anesthetic and obstetric data from women with platelet counts <100 000/µL, who were admitted to a single referral center during 2011-2014. The rate of neuraxial block and related complications were examined in relation to the platelet count and the results combined with published data to assess the risk of spinal-epidural hematoma. RESULTS: During the study period, 471 of 45 462 women (1%) had a low platelet count (<100 000/µL). The rate of neuraxial block was significantly higher in women with platelet counts of 70-99 000/µL (280/394, 71.1%) when compared to women with platelet counts of 50-69 000/µL and 0 to 49 000/µL (23/59, 38.9% and 5/18, 27.8%, respectively, P <0.0001). Women in the lower platelet count ranges had a higher risk of cesarean delivery under general anesthesia and longer hospital stay. No neuraxial hematoma were reported. CONCLUSIONS: This study contributes a substantial series of neuraxial blocks among women with low platelet counts. The findings support that the risk of hematoma is low if the platelet count is <100 000/µL, specifically between 70 and 99 000/µL. Risk assessment in the lower count ranges requires a much larger sample.

A case report spontaneous spinal epidural hematoma diagnosed in a hemophilic child with neck pain

Hemophilia is a disease that causes a hemorrhagic tendency due to a congenital deficiency of blood clotting factors. Hemorrhagic arthritis is the most common complication in hemophilia patients, and hemorrhage in various areas, such as intramuscular hemorrhage and mucosal hemorrhage, can occur. Among the most dangerous complications, central nervous system hemorrhage can occur, which is the most common cause of death in hemophiliacs. An intracerebral hemorrhage in a central nervous system hemorrhage is very rare but occurs spontaneously, and it is often traumatic. Some cases have been reported in foreign countries, but there are no cases reported in Korea. Most cases reported in foreign countries occurred in the cervical to the thoracic regions, but there are no cases in only the cervical region. This paper reports a case of spinal epidural hematoma that developed spontaneously in a child with hemophilia complaining of neck pain.

[Research progress on early diagnosis, reasonable prevention and treatment of symptomatic spinal epidural hematoma following spinal surgery].

Symptomatic spinal epidural hematoma (SSEH) following spinal surgery is rare but one of the serious complications. SSEH can leave devastating neurological consequences if missing the optimal timing for treatment. The early diagnosis of SSEH is critical to the neurologic recovery, and MRI examination can help to check the location and the scope of the hematoma and provide imaging information for surgical operation. The risk factors of SSEH can be divided into preoperative factors, intraoperative factors and postoperative factors. The occurrence of SSEH can be minimized by controlling the risk factors, exact hemostasis and reasonable perioperative management. Patients with mild paralysis can choose conservative treatment, while patients with severe or progressive nerve injury (manual muscle testing <3) and unendurable nerve root pain should choose to clean the hematoma and decompress the nerve as soon as possible.

Symptomatic epidural haematoma after cervical laminoplasty: a report of three cases.

Symptomatic epidural haematoma after cervical laminoplasty is rare. We report 3 patients who required emergency evacuation of an epidural haematoma. Timely diagnosis and removal of the haematoma is important to prevent neurological deficits. The causative factors in these patients were preoperative coagulopathy, hypertension, and the malfunction of a closed-suction drain.

Anticoagulantes e bloqueios do neuroeixo / Anticoagulants and neuraxial blockade

O número de pacientes em uso de fármacos anticoagulantes ou que alteram a hemostasia tem aumentado em virtude da maior expectativa de vida da população, do advento de medicamentos mais seguros e do aumento na prevalência de doenças cardiovasculares. A anestesia por bloqueio do neuroeixo quando realizada nesses pacientes traz o risco de sangramento e hematoma espinhal. Apesar da incidência estimada de complicações hemorrágicas associadas a bloqueios neuroaxiais ser baixa, além de imprecisa, a gravidade de suas consequências torna imperativo o desenvolvimento de estratégias que aumentem a segurança no procedimento anestésico desses pacientes. Entretanto, as recomendações baseadas em evidências são fracas, pois se baseiam principalmente em relatos de casos, pequenos estudos e farmacocinética das drogas. Neste artigo, revisamos a literatura sobre técnicas neuroaxiais realizadas em pacientes em uso de drogas anticoagulantes e/ou que alteram a hemostasia, com o objetivo de auxiliar o anestesiologista no manejo mais seguro e de qualidade para os pacientes.

The number of patients using anticoagulants or drugs that alter hemostasis has increased because of increased life expectancy, advent of safer medicines, and increased prevalence of cardiovascular diseases. In these patients, anesthesia by neuraxial blockade brings the risk of bleeding and spinal hematoma. Despite the estimated incidence of hemorrhagic complications associated with neuraxial blockade being low and inaccurate, the gravity of its consequences makes the development ofstrategies that increase the safety in the anesthetic procedures in these patients imperative. However, evidence-based recommendations are weak because they are based primarily on case reports, small studies, and drugs pharmacokinetics. In this article, we reviewed the literature on neuraxial techniques performed in patients using anticoagulant drugs, and/or those that alter hemostasis, with the objective of assisting the anesthesiologist to improve the quality and safety in these patients? management.

Cervical epidural haematoma causing Brown-Sequard syndrome: a case report.

Brown-Sequard syndrome secondary to compression of the spinal cord by an epidural haematoma following minor trauma is rare. A 65-year-old woman presented with neck pain and sudden onset hemiplegia with contralateral anaesthesia. Magnetic resonance imaging showed a haematoma in the epidural space in the C3 to C5 levels. She underwent open-door laminoplasty for evacuation of the haematoma. At the 2-year follow-up, she had regained normal sensations and a neurological grade of 5/5.

Spontaneous Spinal Epidural Hematoma Caused by Dual Antiplatelet Agent Therapy after Percutaneous Coronary Intervention / 대한내과학회지

Spontaneous spinal epidural hematomas (SSEH) are rare, accounting for less than 1% of all spinal epidural lesions. The potential causes include coagulopathies, antithrombotic drugs, hypertension, increased venous pressure, and vascular malformations. A SSEH causes severe neurological deficits unless treated in a timely manner. As the number of patients who are diagnosed with ischemic heart disease and treated using percutaneous coronary intervention (PCI) increases, the prescription of dual antiplatelet agents is also increasing. We report a case of SSEH caused by dual antiplatelet agent therapy in a patient who had undergone PCI.

Análise epidemiológica de 210 casos de hematoma extradural traumático tratados cirurgicamente / Epidemiological analysis of 210 cases of surgically treated traumatic extradural hematoma

OBJETIVO: Analisar aspectos da epidemiologia, apresentação clínica e radiológica de pacientes com hematoma extradural traumático (HED) submetidos a procedimento neurocirúrgico. MÉTODOS: Foi realizada a revisão de prontuários de 210 pacientes admitidos no Serviço de Emergência com HED diagnosticados através de tomografia computadorizada, tratados cirurgicamente no período de agosto de 1998 a janeiro de 2008. Foram analisados: idade, sexo, apresentação clínica e radiológica, mecanismo de trauma e status neurológico no momento da alta hospitalar. RESULTADOS: Em 49,2% o mecanismo de trauma foi queda; 89,2% dos pacientes eram do gênero masculino; 49,7% dos casos tinham Escala de Coma de Glasgow (ECG) entre 13-15; 61% dos pacientes tinham idade entre 20-49 anos; A localização do HED em 26,5% e 19,6% dos casos foi têmporo-parietal e temporal, respectivamente; 32,8% tinham lesões intracranianas associadas, sendo a fratura craniana evidenciada em cerca de 45% dos casos; 76,2% dos pacientes tratados cirurgicamente tiveram alta com déficit mínimo ou ausência de déficit neurológico. CONCLUSÃO: Observamos que o HED, na população de estudo, apresenta-se mais frequentemente no gênero masculino, na quarta década de vida, mais relacionado às quedas. Na admissão, observamos uma ECG entre 13 e 15, sendo pertinente mencionar o envolvimento da região têmporo-parietal na maioria dos casos. Acreditamos que o conhecimento da epidemiologia do hematoma extradural traumático pode auxiliar na elaboração de medidas de saúde pública, visando à prevenção e identificação precoce desta doença em determinada população.

OBJECTIVE: To assess the epidemiology, clinical and radiological presentation of patients with traumatic extradural hematoma (EDH) undergoing neurosurgical procedures. METHODS: We performed a chart review of 210 patients admitted to the emergency department with EDH diagnosed by CT scan and surgically treated between August 1998 and January 2008. Variables analyzed were: age, gender, clinical and radiological presentation, mechanism of injury and neurological status at discharge from hospital. RESULTS: In 49.2% trauma mechanism was fall; 89.2% of patients were male, 49.7% of cases had a Glasgow Coma Scale (GCS) between 13 and 15; 61% of patients had age between 20 and 49 years; the location of EDH was the temporo-parietal and temporal in 26.5% and 19.6% of the cases, respectively; 32.8% had associated intracranial lesions, with skull fractures seen in around 45% of cases; 76.2% of surgically treated patients were discharged with minimal or no neurologic deficit. CONCLUSION: We observed that, in the study population, EDH appears more often in males, in the fourth decade of life, and is more related to falls. On admission, GCS was observed between 13 and 15 and it is appropriate to mention the involvement of the temporo-parietal region in most cases. We believe that knowledge of the epidemiology of traumatic epidural hematoma can assist in developing public health measures aimed at prevention and early identification of this disease in the population.

Acute epidural hematoma after thoracic spine surgery / 中华骨科杂志

Objective To investigate the risk factors and preventive measures for acute epidural hematoma after posterior thoracic spine surgery.Methods A retrospective study of 14 patients who developed acute epidural hematoma after thoracic spine surgery from May 2002 to May 2012 was conducted.There were 6 males and 8 females,aged from 41 to 69 years (average,61.2 years).There were 10 cases of thoracic spinal canal stenosis,3 cases of thoracic spinal meningioma,and 1 case of thoracic metastasis.About 3-14 h (average,6.6 h) after posterior thoracic spine surgery,the neurological deterioration was found,and according to the American Spinal Injury Association (ASIA) classification,there were 5 cases of grade A and 9 cases of grade B.The neurological function before evacuation of hematoma was compared with that after evacuation of hematoma and that at final follow-up.The correlations between hematoma compression time,neurological improvement rate and neurological function before evacuation of hematoma were statistically analyzed.Results After evacuation of hematoma,the ASIA classification of 14 patients was as follows:grade B in 1 case,grade C in 2 cases,grade D in 4 cases,and grade E in 7 cases.The hematoma compression time of 3 patients with grade B or C was more than 10 hours.Obvious difference of neurological function was found before and after evacuation of hematoma.The neurological improvement rate was 63.7％±23.3％ after evacuation of hematoma,which was negatively correlated with hematoma compression time and positively correlated with preoperative neurological function.The neurological function before evacuation of hematoma was significantly different from that at final follow-up.The neurological improvement rate was 86.97％±17.58％ at final follow-up,which was negatively correlated with hematoma compression time and positively correlated with preoperative neurological function.Conclusion The acute epidural hematoma after thoracic spine surgery could cause severe neurological deterioration.The neurological improvement was negatively correlated with hematoma compression time.Evacuation of hematoma must be done as soon as possible once progressive neurological deterioration is found.

Optimum dose of normal saline for preloading epidural space required to prevent injury to blood vessel by epidural catheter placement for caesarean section / 中华麻醉学杂志

Objective To determine the optimum dose of normal saline (NS) for preloading epidural space required to prevent the injury to blood vessel by epidural catheter placement for caesarean section.Methods Two hundred ASA Ⅰ or Ⅱ parturients with a single baby at full term in vertex presentation,aged 24-35 yr,weighing 63-78 kg,scheduled for caesarean section under continuous epidural anesthesia,were randomly divided into4 groups (n-50 each):control group (group Ⅰ),NS2 ml group (group Ⅱ),NS5 ml group (group Ⅲ)and NS 10 ml group (group Ⅳ).The epidural puncture was performed at L2-3 interspace with a Tuohy needle attached to a 5 ml syringe.Loss of resistance was used to identify the epidural space.In group C no fluid was injected into the epidural space before insertion of the catheter,while in groups Ⅱ,Ⅲ and Ⅳ NS 2,5 and 10 ml were injected into the epidural space before the catheter insertion respectively.After a test dose of 3 ml 1.5％ lidocaine,0.75％ ropivacaine 10-20 ml was administered through the epidural catheter.MAP and HR were recorded before epidural puncture (T0),at 10 and 20 min after the end of epidural administration (T1.2),and at the end of surgery (T3).The number of patients in whom blood or blood tinted fluid was withdrawn from the epidural catheter was recorded.The amount of ropivacaine consumed was recorded.The upper level of anesthesia was measured by pin-prick and the degree of motor block was assessed using modified Bromagc scale at T2.Results The hemodynamic parameters were in the normal range in the four groups.MAP was significantly lower at T2,the upper level of anesthesia was significantly higher,and the degree of motor block was significantly smaller in group Ⅳ than in groups Ⅰ,Ⅱ and Ⅲ (P ＜ 0.05).There was no significant difference in MAP among groups Ⅰ,Ⅱ and Ⅲ (P ＞ 0.05).There was no significant difference in HR and the amount of ropivacaine consumed among the four groups (P ＞ 0.05).The number of patients in whom blood or blood tinted fluid was withdrawn fiom epidural catheter was significantly smaller in groups Ⅲ and Ⅳ compared with groups Ⅰ and Ⅱ (P ＜ 0.05).Conclusion Preloading the epidural space with NS 5 ml can prevent the occurrence of injury to blood vessel induced by insertion of epidural catheter with no influence on the efficacy of anesthesia and NS 5 ml is the optimum dose.

BACKGROUND AND OBJECTIVES: Spinal hematomas are rare and they affect the central nervous system. They can cause permanent neurologic sequelae and death if they are not treated properly. Early diagnosis and treatment are fundamental for a good neurologic prognostic. The objective of this report was to emphasize for anesthesiologists the importance of early diagnosis and treatment of spinal hematomas, besides improving their prevention. CASE REPORTS: Case 1: The patient underwent epidural lumbar anesthesia for femoropopliteal revascularization. He was being treated with acetylsalicylic acid, clopidogrel, and enoxaparin, which were discontinued before the surgery. The patient developed paraplegia in the immediate postoperative period. Neurosurgical decompression was performed after the diagnosis, but without recovery in the long run. Case 2: The patient underwent epidural lumbar anesthesia for right knee osteotomy, without intercurrences. The patient remained without neurological complaints until approximately 48 hours after the surgery when he developed urinary retention, pain in the right lower limb, paresthesias, and difficulty moving both feet. The MRI showed an epidural lumbar hematoma, and the patient underwent immediate surgical decompression. He showed complete neurological recovery after 10 months of rehabilitation. CONCLUSIONS: The clinical cases presented here showed different outcomes, indicating the importance of early diagnosis and treatment for a good evolution. Diagnosis by MRI with early decompression shortly after the development of the first clinical manifestations remains the standard treatment. Identification of patients at risk for neuraxial bleeding and change in anesthetic technique, as well as the establishment of postoperative neurologic evaluation protocols in patients undergoing neuraxial anesthesia can contribute for prevention of severe neurologic sequelae.

Dolor radicular como forma de presentación de un hematoma epidural espontáneo / Radicular pain as way of presentation of a spontaneous spinal epidural hematoma: a case presentation

Las hemorragias espontáneas dentro del estuche espinal en las edades pediátricas son poco frecuentes. La sangre puede extenderse por el espacio epidural, subdural o intramedular y producir compresión de las estructuras neurales. El espacio epidural es la zona más vulnerable a sufrir el sangrado y dentro de éste su porción posterior. Objetivo: presentar un caso poco frecuente de hematoma epidural espinal cervical espontáneo que debutó con signos radiculares. Caso Clínico: paciente masculino de 14 años de edad con antecedentes de salud que es remitido a la consulta con una historia iniciada siete días antes, caracterizada por: dolor cervical bajo, de moderada intensidad de inicio brusco y que se irradiaba a los dermatomas cervicales 4 a 6 (C4-C6). Al examen físico se pudo constatar dolor al percutir las apófisis espinosas de C4 a C6, hiporreflexia bicipital y reducción de la fuerza en la pinza digital derecha. Se realizó una resonancia magnética nuclear cervical, donde se pudo diagnosticar un hematoma epidural espinal espontáneo que se extendía anteriormente desde C3 a C7. Se decidió el tratamiento médico y el paciente egresó a los doce días libre de manifestaciones clínicas. Conclusiones: la evolución clínica del paciente, el tamaño, la localización del hematoma y tiempo de evolución de la enfermedad son elementos a tener en cuenta a la hora de seleccionar la modalidad del tratamiento, el cual permitirá la reversibilidad de los síntomas y signos neurológicos así como el desarrollo de complicaciones tardías.

Spontaneous hemorrhages inside the spinal case in pediatric ages are not frequent. The blood may extend over the epidural, subdural or intramedular space, producing compression of neural structures. The epidural space is the most vulnerable area to suffer bleeding and inside of this, its posterior portion. Objective: to present an infrequent case of spontaneous cervical spinal epidural hematoma that started with radicular signs. Clinical case: a 14 years old, masculine patient with health antecedents is remitted to the consulting room with a history initiated seven days before, characterized for: low cervical pain of moderate intensity, of abrupt onset, irradiating to the 4 at 6 cervical dermatomes (C4-C6). To the physical examination was verified pain when striking the C4 to C6, bicipital hyporeflexia and reduction of the force in the right digital forceps. A cervical nuclear magnetic resonance was performed, where a spontaneous spinal epidural hematoma was diagnosed that previously extended from C3 to C7. The medical treatment was decided, the patient was discharged to twelve days, free of clinical manifestations. Conclusions: the patient's clinical evolution, size, localization of the hematoma and the time of evolution of the disease are elements to keep in mind when selecting the modality of the treatment, which will allow the reversibility of symptoms and neurological signs as well as the development of late complications.

Spontaneous spinal epidural hematomas associated with acute myocardial infarction treatment.

Many studies have reported spontaneous spinal epidural hematoma (SSEH). Although most cases are idiopathic, several are associated with thrombolytic therapy or anticoagulants. We report a case of SSEH coincident with acute myocardial infarction (AMI), which caused serious neurological deficits. A 56 year old man presented with chest pain accompanied with back and neck pain, which was regarded as an atypical symptom of AMI.
