Spontaneous intracranial hypotension: key features for a frequently misdiagnosed disorder.

Neurol Sci 2020 Apr 27. Epub 2020 Apr 27.

School of Medicine and Health Sciences, Tecnologico de Monterrey Campus Guadalajara, Zapopan, Mexico.

Spontaneous intracranial hypotension (SIH) is a rare neurological condition caused by low cerebrospinal fluid (CSF) volume, most commonly due to a CSF leak. The most common presenting symptom is an orthostatic headache, but some patients may present with atypical neurological manifestations such as cranial nerve palsies, an altered mental status, and movement disorders, which complicate the clinical diagnosis. Therefore, the diagnosis is based on the combination of clinical signs and symptoms, neuroimaging, and/or a low cerebrospinal fluid pressure. Read More

Spontaneous Intracranial Hypotension: Case Study and Review of the Literature.

Cureus 2020 Feb 17;12(2):e7018. Epub 2020 Feb 17.

Neurosurgery, Kaiser Permanente Fontana Medical Center, Fontana, USA.

Spontaneous intracranial hypotension (SIH) is a pathology characterized by orthostatic headaches, diffuse pachymeningeal enhancement on magnetic resonance imaging (MRI), and low to normal cerebrospinal fluid (CSF) pressures. We present the case of a 46-year-old male with refractory postural headaches, found to have a diffuse CSF leak throughout the cervicothoracic (C1-T12) spine. His neurological status declined rapidly to a Glasgow Coma Scale (GCS) of eight, necessitating bilateral subdural drain placement. Read More

Incidence and Effect of Diabetes Insipidus in the Acute Care of Patients with Severe Traumatic Brain Injury.

Neurocrit Care 2020 Mar 23. Epub 2020 Mar 23.

Department of Intensive Care Medicine, Fundación Valle del Lili, Carrera 98 #18-49, Cali, Colombia.

Background: Literature on diabetes insipidus (DI) after severe traumatic brain injury (TBI) is scarce. Some studies have reported varying frequencies of DI and have showed its association with increased mortality, suggesting it as a marker of poor outcome. This knowledge gap in the acute care consequences of DI in severe TBI patients led us to conceive this study, aimed at identifying risk factors and quantifying the effect of DI on short-term functional outcomes and mortality.

A ruptured posterior communicating artery aneurysm presenting as tentorial and spinal isolated subdural hemorrhage: a case report and literature review.

BMC Neurol 2020 Mar 18;20(1):102. Epub 2020 Mar 18.

Diagnostic and Interventional Radiology Department, Imam Abdulrahman Bin Faisal University, King Fahd Hospital of the University, P.O. Box: 4398, Al-Khobar City, Eastern Province, 31952, Saudi Arabia.

Background: Ruptured intracranial aneurysms are often associated with subarachnoid or intraparenchymal hemorrhage. However, the prevalence of subdural hemorrhage post aneurysmal rupture is low and rarely reported in scientific studies. Here, we report an unusual case of a ruptured posterior communicating artery aneurysm resulting in an isolated subdural hematoma located in the tentorial and spinal canal without subarachnoid or intraparenchymal hemorrhage.

Fetal subdural hematoma, sickle cell disease and storage pool disease: A case report.

Case Rep Womens Health 2020 Apr 20;26:e00183. Epub 2020 Feb 20.

Department of Obstetrics and Gynecology, University Hospital, University of Duisburg-Essen, Essen, Germany.

A fetal subdural hematoma (SDH) was diagnosed in a patient with sickle cell disease (SCD) during a routine ultrasound exam in the 30th week of pregnancy. A scan performed a few days earlier had revealed no abnormalities. After interdisciplinary consultation with neurosurgeons and neonatologists, a cesarean section was performed since acute subdural bleeding was hypothesized and the mother's condition was critical.

Advances and Future Directions of Diagnosis and Management of Pediatric Abusive Head Trauma: A Review of the Literature.

Front Neurol 2020 20;11:118. Epub 2020 Feb 20.

Department of Pediatrics, Virginia Commonwealth University, Richmond, VA, United States.

Abusive head trauma (AHT) is broadly defined as injury of the skull and intracranial contents as a result of perpetrator-inflicted force and represents a persistent and significant disease burden in children under the age of 4 years. When compared to age-matched controls with typically single occurrence accidental traumatic brain injury (TBI), mortality after AHT is disproportionately high and likely attributable to key differences between injury phenotypes. This article aims to review the epidemiology of AHT, summarize the current state of AHT diagnosis, treatment, and prevention as well as areas for future directions of study. Read More

A Rare Case Presentation of Apixaban-induced Nontraumatic Spinal Subdural Hematoma.

Cureus 2020 Jan 22;12(1):e6743. Epub 2020 Jan 22.

Radiology, Atlantic Medical Imaging, Galloway, USA.

A spinal subdural hematoma is a rare clinical entity and an uncommon urgent complication that can be associated with the use of vitamin K and less commonly nonvitamin K oral anticoagulants. It is considered a neurological emergency requiring prompt diagnosis and surgical intervention in the majority of the cases. Herein, we present an 84-year-old male patient with a history of nonvalvular atrial fibrillation on apixaban who presented with complaints of bilateral lower extremity weakness, severe back pain, and urinary retention.

Mild traumatic brain injuries with minor intracranial hemorrhage: Can they Be safely managed in the community? - A cohort study.

Int J Surg 2020 Apr 17;76:88-92. Epub 2020 Feb 17.

Department of Surgery, Massachusetts General Hospital, Boston, MA, USA. Electronic address:

Background: Patients with mild traumatic brain injury (mTBI) are frequently transferred to level 1 trauma centers (L1TC) if they have minor findings on a computerized tomographic scan of the head due to the absence of continuous neurosurgical coverage in community hospitals (CH). We hypothesized that such patients can be safely managed at community hospitals with a qualified Trauma team.

Methods: This is a multicentered Retrospective Cohort Study. Read More

Comparison of Traumatic Intracranial Hemorrhage Expansion and Outcomes Among Patients on Direct Oral Anticoagulants Versus Vitamin k Antagonists.

Neurocrit Care 2020 04;32(2):407-418

Department of Neurology, Johns Hopkins School of Medicine, Baltimore, MD, USA.

Background: With increasing use of direct oral anticoagulants (DOACs) and availability of new reversal agents, the risk of traumatic intracranial hemorrhage (tICH) requires better understanding. We compared hemorrhage expansion rates, mortality, and morbidity following tICH in patients treated with vitamin k antagonists (VKA: warfarin) and DOACs (apixaban, rivaroxaban, dabigatran).

Methods: Retrospective chart review of patients from 2010 to 2017 was performed to identify patients with imaging diagnosis of acute traumatic intraparenchymal, subdural, subarachnoid, and epidural hemorrhage with preadmission use of DOACs or VKAs. Read More

Critical Depressed Brain Volume Influences the Recurrence of Chronic Subdural Hematoma after Surgical Evacuation.

Sci Rep 2020 Jan 24;10(1):1145. Epub 2020 Jan 24.

Department of Neurosurgery, Chung-Ang University Hospital, Chung-Ang University College of Medicine, Seoul, Republic of Korea.

Recurrence of chronic subdural hematoma (CSDH) frequently occurs after surgical evacuation. However, the value of follow-up postoperative imaging and measuring volumetric factors to predict recurrence are still controversial. Herein, we aimed to assess the optimal timing for follow-up referential imaging and the critical depressed brain volume for CSDH recurrence. Read More

Traumatic Parafalcine Subdural Hematoma: A Clinically Benign Finding.

J Surg Res 2020 May 8;249:99-103. Epub 2020 Jan 8.

Department of Surgery, Allegheny General Hospital, Pittsburgh, Pennsylvania.

Background: Guidelines for management of intracranial hemorrhage do not account for bleed location. We hypothesize that parafalcine subdural hematoma (SDH), as compared to convexity SDH, is a distinct clinical entity and these patients do not benefit from critical care monitoring or repeat imaging.

Methods: We identified patients presenting to a single level I trauma center with isolated head injuries from February 2016 to August 2017. Read More
