Spontaneous epidural haematoma in a paediatric patient with sickle cell disease.

Spontaneous epidural haematoma (SEDH) is a rare complication of sickle cell disease (SCD). To our knowledge, 38 cases of patients with SEDH associated with SCD have been reported in the literature. In this case report we describe the first Danish paediatric case with SCD and SEDH. The pathophysiology of this association is not fully understood, but skull bone infarction, haemopoietic marrow expansion or compromised blood flow due to hyper viscosity might contribute to this rare complication. In patients with SCD presenting with relevant symptoms, early imaging could be considered.

Recurrent Nontraumatic Subgaleal Hematomas in a Pediatric Patient With Sickle Cell Disease.

Spontaneous subgaleal hematoma in pediatric patients with sickle cell disease (SCD) is a rare occurrence that can present with symptoms mimicking ischemic stroke, a known complication of SCD. However, unlike ischemic stroke, subgaleal hematoma is nonlethal and can be managed conservatively without major sequelae. Here, we present the case of an adolescent with SCD who presented with 2 episodes of subgaleal and epidural hematomas, 2 years apart. The latter episode occurred while on crizanlizumab, an anti-P-selectin antibody, approved for use in SCD in 2019 to reduce the number of acute pain crises. We demonstrate the diagnosis of subgaleal hematoma and outline steps to conservative management which were safe and did not lead to focal neurologic deficits.

Pediatric head injuries: particularities and neurosurgical experience in a lower-middle income country.

PURPOSE: To the best of our knowledge, this is the first study conducted in Tunisia on the neurosurgical management of child cranial trauma. The objectives of the present work were to identify the causes of pediatric head injuries, explore epidemiological and clinical specificities, and analyze the short- and long-term postoperative evolution. METHODS: A retrospective review was conducted on one hundred children with head injuries over a five-year period at one of the largest neurosurgery departments in Tunisia. The collected data encompassed demographic information, clinical presentation features, neuroimaging characteristics, surgical management, complications, and outcomes. RESULTS: Over a five-year period, we have found 118 children who have undergone surgery, representing an annual incidence of twenty-four children per year. The average age was 10 years. Falls emerged as the primary cause of childhood head injuries in our series, followed by road traffic accidents. The most frequently encountered initial sign was the loss of consciousness (52%), followed by headaches (28%), vomiting (25%), and seizures (8%). The average time between the accident and admission to the operating unit was 10 h. Various neurosurgeries were performed, with the evacuation of an epidural hematoma being the most common procedure. At a median follow-up of 24 months, the outcomes were favorable in 88% of cases. CONCLUSION: The main prognostic factors for head trauma in children included age, circumstances of the accident, association with polytrauma, the initial Glasgow Coma Scale, the nature of the initial cerebral lesions, and the timeliness and quality of initial management.

Epidural Hematoma related to lower limb pain and massive liver bleeding in Gorham-Stout disease: A case report.

RATIONALE: Gorham-Stout disease (GSD) is a rare disease that causes massive osteolysis and proliferation of abnormal lymphangiomatous tissues. Patients with GSD often experience pain associated with bone fractures and chylothorax. However, bleeding caused by abnormal lymphangiomatous tissue or hematological dysfunction rarely occurs. PATIENT CONCERNS: A 22-year-old female patient with GSD presented with severe left hip and lower limb pain. The GSD had disappeared her right pelvic bone and femur, but no abnormalities were found in the bones at the site of the pain. DIAGNOSES: The patient presented with a chylothorax and cerebrospinal fluid leakage. She was treated with sirolimus and an epidural blood patch, and her symptoms resolved. Computed tomography and magnetic resonance imaging revealed an epidural hematoma extending from L3 to the caudal region, and blood results revealed a consumption coagulopathy. INTERVENTIONS: We presumed that the hematoma caused pain and prescribed pregabalin and morphine. The pain gradually subsided. OUTCOMES: An unexpected liver subcapsular hemorrhage occurred 4 months later, and the patient went into hemorrhagic shock. Transcatheter arterial embolization was promptly performed, and the patient recovered. LESSONS: GSD infrequently causes bleeding related to abnormal lymphangiomatous tissues and coagulopathy, yet it can lead to serious events if it occurs.

Computed Tomography Lesions and Their Association With Global Outcome in Young People With Mild Traumatic Brain Injury.

Mild traumatic brain injury (mTBI) can be accompanied by structural damage to the brain. Here, we investigated how the presence of intracranial traumatic computed tomography (CT) pathologies relates to the global functional outcome in young patients one year after mTBI. All patients with mTBI (Glasgow Coma Scale: 13-15) ≤24 years in the multi-center, prospective, observational Collaborative European NeuroTrauma Effectiveness Research in TBI (CENTER-TBI) study were included. Patient demographics and CT findings were assessed at admission, and the Glasgow Outcome Scale Extended (GOSE) was evaluated at 12 months follow-up. The association between a "positive CT" (at least one of the following: epidural hematoma, subdural hematoma, traumatic subarachnoid hemorrhage (tSAH), intraventricular hemorrhage, subdural collection mixed density, contusion, traumatic axonal injury) and functional outcome (GOSE) was assessed using multi-variable mixed ordinal and logistic regression models. A total of 462 patients with mTBI and initial brain CT from 46 study centers were included. The median age was 19 (17-22) years, and 322 (70%) were males. CT imaging showed a traumatic intracranial pathology in 171 patients (37%), most commonly tSAH (48%), contusions (40%), and epidural hematomas (37%). Patients with a positive CT scan were less likely to achieve a complete recovery 12 months post-injury. The presence of any CT abnormality was associated with both lower GOSE scores (odds ratio [OR]: 0.39 [0.24-0.63]) and incomplete recovery (GOSE <8; OR: 0.41 [0.25-0.68]), also when adjusted for demographical and clinical baseline factors. The presence of intracranial traumatic CT pathologies was predictive of outcome 12 months after mTBI in young patients, which might help to identify candidates for early follow-up and additional care.

Anaesthetic management of a toddler with uncorrected tetralogy of Fallot undergoing surgery for epidural haematoma.

The literature on the anaesthetic management of a toddler presenting to the emergency department with an acute epidural haematoma with an uncorrected tetralogy of Fallot is sparse and management can be challenging. The main anaesthetic goals are to increase or maintain systemic vascular resistance and decrease pulmonary vascular resistance for cardiovascular stability, while maintaining cerebral perfusion pressure and decreasing intracranial pressure for cerebral protection. Thus, a balanced approach is desirable while managing such cases from emergency to the intensive care unit.

A Rare Case of Postoperative Extradural Hematoma in the Posterior Fossa Complicated by Both Stunned Myocardium and Neurogenic Pulmonary Edema.

Acute neurological insult can trigger a cascade of events in other organ systems such as the heart and lung. Neurogenic stunned myocardium (NSM) and Neurogenic pulmonary edema (NPE) are mostly reported after stroke, subarachnoid hemorrhage, or seizures whenever sympathetic storm and autonomic dysregulation occurs. We report here for the first time, a case of postoperative infratentorial extradural hematoma in a patient triggering NSM and NPE at the same time. The challenges involved in the management of such a patient are described in this case report. The patient was successfully managed and discharged home with no new neurological deficits.

[Rare association of subperiosteal hematoma of the orbit with frontal extradural hematoma: a case report]. / Association rare d'un hématome sous-périosté de l'orbite et d'un hématome extradural frontal: à propos d'un cas.

Subperiosteal haematoma of the orbit associated with frontal extradural hematoma is very rare. We here report a case treated in our Department with a literature review. The study involved a 15-year-old boy, victim of head injury from white weapon, a week before his admission to the emergency room. He had inflammatory and painful exophthalmos on the left side, associated with left ophthalmoplegia and blindness. Brain scanner showed left frontal extradural hematoma associated with subperiosteal hematoma of the ipsilateral orbit. Frontal craniotomy associated with fracture orbitotomy allowed evacuation of the extradural hematoma, and then, of the subperiosteal hematoma. Patient´s outcome was favorable. Simultaneous occurrence of frontal extradural hematoma and subperiosteal hematoma of the orbit is extremely rare. Generally, attention is drawn by exophthalmos and visual disturbances. Emergency brain scan without contrast agent injection can be used to make a diagnosis. Prognosis depends on visual function, then adequate management helps to safeguard the eye and vision.

A proposed novel traumatic brain injury classification system - an overview and inter-rater reliability validation on behalf of the Society of British Neurological Surgeons.

INTRODUCTION: The measurement of traumatic brain injury (TBI) 'severity' has traditionally been based on the earliest Glasgow Coma Score (GCS) recorded, however, the underlying parenchymal pathology is highly heterogonous. This heterogeneity renders prediction of outcome on an individual patient level inaccurate and makes comparison between patients both in clinical practice and research difficult. The complexity of this heterogeneity has resulted in generic all encompassing 'traumatic brain injury protocols'. Early management and studies of neuro-protectants are often done irrespective of TBI type, yet it may well be that a specific treatment may be beneficial in a subset of TBI pathologies. METHODS: A simple CT-based classification system rating the recognised types of blunt TBI (extradural, subdural, subarachnoid haemorrhage, contusions/intracerebral haematoma and diffuse axonal injury) as mild (1), moderate (2) or severe (3) is proposed. Hypoxic brain injury, a common secondary injury following TBI, is also included. Scores can be combined to reflect concomitant types of TBI and predominant location of injury is also recorded. To assess interrater reliability, 50 patient CT images were assessed by 5 independent clinicians of varying experience. Interrater reliability was calculated using overall agreement through Cronbach's alpha including confidence intervals for intra-class coefficients. RESULTS: Interrater reliability scores showed strong agreement for same score and same injury for TBIs with blood on CT and Cronbach's alpha co-efficient (range 0.87-0.93) demonstrated excellent correlation between raters. Cronbach's alpha was not affected when individual raters were removed. CONCLUSIONS: The proposed simple CT classification system has good inter-rater reliability and hence potentially could enable better individual prognostication and targeted treatments to be compared while also accounting for multiple intracranial injury types. Further studies are proposed and underway.

Endovascular treatment of traumatic oronasal hemorrhage complicated with progressive acute epidural hemorrhage: A case report.

RATIONALE: Massive oronasal hemorrhage can induce shock and is life-threatening, and early endovascular treatment is the standard of care. Few studies have reported the use of endovascular treatment for acute epidural hemorrhage (AEDH). However, endovascular treatment of oronasal hemorrhage complicated by AEDH has not yet been demonstrated. Many patients with a low to moderate volume of oronasal hemorrhage complicated by AEDH choose conservative treatment but eventually undergo craniotomy due to increased intracranial hemorrhage. PATIENT CONCERNS: A 32-year-old man presented to our hospital with traumatic oronasal hemorrhage complicated by AEDH after being hit by a blunt object. DIAGNOSIS: Computerized tomography suggested progressive AEDH and multiple basilar skull fractures. Emergency cerebral angiography showed rupture of the right middle meningeal artery and a branch of the left maxillary artery causing AEDH and oronasal hemorrhage. INTERVENTIONS: The patient underwent interventional embolization to treat the ruptured intracranial vessels. OUTCOMES: After 23 days, cranial computerized tomography showed remarkable absorption of the right frontal epidural hematoma, with the patient having a Glasgow Coma Scale score of 15. LESSONS: This case provides a valuable treatment for patients with AEDH complicated with oronasal hemorrhage, early interventional embolization may be an effective treatment strategy to prevent further complications and ensure a good patient outcome.

Extra-axial hematomas due to road traffic accidents and their outcome: a ten-year study.

OBJECTIVE: The main objectives of this study were to describe the epidemiological characteristics, the associated factors and outcomes of extra-axial hematoma (EAH) in patients of traumatic brain injury (TBI) due to road traffic accident (RTA) and to assess their survival probability after 6 and 12 months to RTA. PATIENTS AND METHODS: This was a retrospective record-based study. A total of 520 patients diagnosed with EAH due to RTA-related TBI were studied. This study covered ten years from January 1, 2010, to December 31, 2019. Descriptive statistics, including frequencies, percentages, mean, standard deviation, median and range were used. To test for significance in the difference between proportions, a chi-square test was applied and adjusted standardized residual to confirm the differences between groups. The Kaplan-Meier curve was plotted, and mean survival rates were calculated for each type of EAH. A two-sided p-value less than 0.05 (5%) at 95% CI was considered to be statistically significant. RESULTS: EAH occurred in 42.1% of RTA-related TBI. Subdural hematoma (SDH) was the most common RTA-related EAH. Age and sex differences exist in the type of EAH with male preponderance and a significantly higher rate of SDH in patients aged 55 years or above. The total EHA mortality was 18.7%, and most occurred within the first month of the incident. Traumatic subarachnoid hemorrhage (tSAH) was associated with poorer outcome in terms of mortality. Epidural hematoma (EDH) has the best prognosis and survival probability at six months and one year from the accident. CONCLUSIONS: Extra-axial hematomas are very common in RTA-related TBIs and have high mortality. SDH is the most common, tSAH had the highest mortality, while EDH has the best survival. Aggressive efforts are compulsory to reduce RTA-related TBI.

Surgical treatment of a spontaneous spinal epidural hematoma under antithrombotic treatment of a multisystem inflammatory syndrome in children associated with SARS-COV-2.

Multisystem inflammatory syndrome in children (MIS-C) is a novel syndrome of multisystemic inflammation affecting children. This case report documents an exceptional and severe complication of an epidural hematoma in a 3-year-old boy under the treatment of MIS-C. During the course of the disease, the patient suffered from a hypocoagulable state and an extensive multisegmental epidural hematoma in the cervical spinal canal. This led to severe anterior spinal cord compression and tetraparesis. Extensive emergency surgery had to be carried out to reverse rapid clinical deterioration.

Traumatic retroclival epidural hematoma associated with reversible ipsilateral internal carotid artery stenosis.

INTRODUCTION: Traumatic retroclival epidural hematoma is rare. It is more common in pediatrics than in adults. Although it has been known that these cases are frequently associated with abducens nerve palsy, internal carotid artery stenosis is rarely found with those hematomas. CASE REPORT: An 8-year-old girl was transferred to our hospital following a traffic accident. She had clear consciousness with right abducens nerve palsy. Computed tomography revealed the left side of both retroclival hematoma without clival fracture and subarachnoid hemorrhage at the Sylvian fissure. She also had a fracture of left femoral neck and ipsilateral lung contusion. Magnetic resonance imaging revealed a retroclival hematoma located in the epidural space and severe stenosis of left internal carotid artery (ICA) from the cavernous to supraclinoid portion without evidence of brain contusion. She was managed conservatively, and her right abducens nerve palsy recovered completely without deterioration of other neurological findings. Neuroradiological findings suggested this ICA stenosis as traumatic dissection. She was discharged home 2 months after the traffic accident. CONCLUSION: Retroclival epidural hematoma without clival fracture associated with ipsilateral ICA stenosis is extremely rare. Although the exact mechanism of the ICA stenosis remains unclear, cerebral vascular events should be considered in the cases with traumatic retroclival hematoma.

Spontaneous acute epidural hematoma associated with chronic subdural hematoma due to dural metastasis of gastric carcinoma: a case report and literature review.

Background: Non-traumatic spontaneous acute epidural hematoma (EDH) happening to chronic subdural hematoma (SDH) caused by dural metastases is a rare entity. Pathogenesis can be derived from infection, coagulopathy, and inflammation. Malignant tumors metastasize to dura mater is one of the most infrequent causes. The exact mechanism remains elusive in spite of several possible speculations. The clinical manifestations, management and outcomes vary among reported cases.Case Description: A 45-year-old woman without history of trauma presented with headache, vomiting and disturbance of consciousness and developed brain hernia rapidly. On arival, she has lost into coma with Glasgow coma scale (GCS) score 5, bilateral pupils were not equal, with disappeared reflectance. Emergency imaging prompted large acute EDH, combined with SDH, arising from dural granular neoplasm confirmed intraoperatively. Four days after surgery, the bilateral pupils were equal in size and sensitive to light reflection.Conclusion: Dural metastases can cause EDH, chronic SDH can also be resulted from metastatic tumors of dura mater. When dealing with spontaneous non-traumatic hematoma around the dura mater, to make the precise diagnosis is sometimes doubtful and confusing. The stream of diagnostic thinking should be opened, including medical diseases such as liver and kidney disease, drug history, history of cancer and other possible clues. Thus, a detailed and purposeful systematic medical history review and physical examination is important in order to make more appropriate strategies for the clinic.

Ratio of Optic Nerve Sheath Diameter to Eyeball Transverse Diameter by Ultrasound Can Predict Intracranial Hypertension in Traumatic Brain Injury Patients: A Prospective Study.

BACKGROUND: Measuring optic nerve sheath diameter (ONSD), an indicator to predict intracranial hypertension, is noninvasive and convenient, but the reliability of ONSD needs to be improved. Instead of using ONSD alone, this study aimed to evaluate the reliability of the ratio of ONSD to eyeball transverse diameter (ONSD/ETD) in predicting intracranial hypertension in traumatic brain injury (TBI) patients. METHODS: We performed a prospective study on patients admitted to the Surgery Intensive Care Unit. The included 52 adults underwent craniotomy for TBI between March 2017 and September 2018. The ONSD and ETD of each eyeball were measured by ultrasound and computed tomography (CT) scan within 24 h after a fiber optic probe was placed into lateral ventricle. Intracranial pressure (ICP) > 20 mmHg was regarded as intracranial hypertension. The correlations between invasive ICP and ultrasound-ONSD/ETD ratio, ultrasound-ONSD, CT-ONSD/ETD ratio, and CT-ONSD were each analyzed separately. RESULTS: Ultrasound measurement was successfully performed in 94% (n = 49) of cases, and ultrasound and CT measurement were performed in 48% (n = 25) of cases. The correlation efficiencies between ultrasound-ONSD/ETD ratio, ultrasound-ONSD, CT-ONSD/ETD ratio, and ICP were 0.613, 0.498, and 0.688, respectively (P < 0.05). The area under the curve (AUC) values of the receiver operating characteristic (ROC) curve for the ultrasound-ONSD/ETD ratio and CT-ONSD/ETD ratio were 0.920 (95% CI 0.877-0.964) and 0.896 (95% CI 0.856-0.931), respectively. The corresponding threshold values were 0.25 (sensitivity of 90%, specificity of 82.3%) and 0.25 (sensitivity of 85.7%, specificity of 83.3%), respectively. CONCLUSION: The ratio of ONSD to ETD tested by ultrasound may be a reliable indicator for predicting intracranial hypertension in TBI patients.

Spontaneous extradural hematoma: a rare entity.

Spontaneous onset extradural hematoma (EDH) is a very rare entity and has been seen mostly to be associated with adjacent infective pathologies, dural vascular malformations, extradural metastasis, or coagulopathies. We report a series of two such cases and review the literature. One case presented with spontaneous EDH that was managed conservatively and was diagnosed to have chronic kidney disease later; the other had deranged coagulation profile and liver function secondary to drug induced hepatitis and was operated. Both patients were discharged in a stable condition and were improving on follow up.

Large Vertex Epidural Hematoma: Case Report and Review of Surgical Approaches

Vertex epidural hematomas (VEHs) are a special clinical entity due to their clinical presentation, vascular etiology and options of surgical approach. The clinical suspicion involves recognizing the mechanism of the injury and the correct visualization of the hematoma in computed tomography (CT) coronal sequences. In the present article, we describe a case of a very large (146 mL) VEH with central brain herniation, and provide a technical note on the surgical planning and treatment. A 34-year-old male patient was admitted to the hospital after an injury on the left superior parietal region. The Glasgow coma scale score was 6, and the left pupil of the patient was dilated. The CT scan showed a large epidural hematoma on the vertex between the coronal e lambdoid sutures, and a fracture over the sagittal suture. During the surgery, multiple burr holes were made laterally to the sagittal suture, and after inspection and no visualization of bleeding in the superior sagittal sinus (SSS), we performed a standard biparietal craniotomy. The patient was discharged three days after the surgery without any deficits. Currently, with the improvement in imaging modalities,more cases of VEH are being identified. Identifying the etiology prior to the craniotomy is challenging in severe cases. Tears in the SSS can bleed profusely, and they demand strategies during the craniotomy.With multiple burr holes parallel to the sagittal suture, we can visualize whether there is bleeding in the SSS and design a craniotomy with or without a central osseous bridge to anchor the dura. Neurosurgeons must be prepared to plan a surgical strategy in cases of large VEHs. Due to its rare frequency and bleeding risks, VEHs are considered challenging.

The Impatient Patient and the Unreceptive Receptionist: Darnley v Croydon Health Services NHS Trust [2018] UKSC 50.

In Darnley v Croydon Health Services NHS Trust [2018] UKSC 50, the Supreme Court held that a hospital receptionist's misleading statement about A&E waiting times constituted a breach of duty and that the claimant's decision, based on this misinformation, to leave the hospital did not break the chain of causation when he was left paralysed as a result of a head injury. In this commentary, I argue that while the Supreme Court's treatment of duty of care and breach is, for the most part, a model of doctrinal clarity, its treatment of the causation issue is problematic as it elides the test of whether there has been a break in the chain of causation with that for remoteness. I then comment on the Supreme Court's construction of the patient in medical negligence cases.

Surgical consideration in Hunter syndrome: a case of hydrocephalus and a case of epidural hematoma.

INTRODUCTION: Hunter syndrome (HS) is a rare X-linked lysosomal storage disorder which affects multiple organ systems. Surgical intervention and general anesthesia should be used with caution because of significant airway complications. CASE REPORT: Two HS patients underwent surgery with different prognosis are presented below. In the first case, symptoms of progressive disabilities on motor function, language, intelligence, and development last for 1 year in a 6-year-old boy; magnetic resonance imaging (MRI) showed severe hydrocephalus. Third ventriculostomy was performed in this patient to relieve the hydrocephalus. Unfortunately, this patient died postoperatively due to postsurgical tracheal collapse. In the second case, an 8-year-old girl was referred to our hospital with epidural hematoma because of a falling accident. Trephination surgery was performed under local anesthesia to remove the hematoma. Three days postsurgical, the patient was discharged uneventfully. CONCLUSION: General anesthesia in HS patients was associated with poor prognosis due to respiratory complications. Local anesthesia and less intensified treatment should be recommended.
