Objective: Acute subdural hematoma (ASDH) is generally considered a condition that should be managed surgically. However, some patients initially receive conservative treatment, a subset of whom require surgical intervention later. This study aimed to evaluate the predictors of delayed surgical intervention in ASDH patients who are initially managed conservatively. Methods: From January 2007 to December 2015, 842 patients diagnosed with ASDH were treated at our institution...

We describe an autopsy case of nontraumatic convexal subarachnoid hemorrhage (cSAH) accompanied by sylvian hematoma. A woman in her 50s was found dead in her house. On autopsy, massive cSAH accompanied by sylvian hematoma was observed. Because of the absence of subarachnoid hemorrhage (SAH) in the basal cistern, initial suspicion was that of a traumatic SAH. After a detailed investigation, a ruptured cerebral aneurysm of the distal middle cerebral artery was found in the hematoma, and the cSAH in this case was confirmed to be endogenous...

BACKGROUND AND PURPOSE: Superficial siderosis (SS) is characterized by hemosiderin deposition in the superficial layers of the central nervous system and can be seen during postmortem examination or with iron-sensitive magnetic resonance imaging techniques. The distribution of SS may predict the probable underlying cause. This study aimed to report the prevalence and natural history of SS in a population-based study. METHODS: Brain magnetic resonance imaging scans from the MCSA (Mayo Clinic Study of Aging), a population-based study of residents 50 to 89 years of age in Olmsted County, Minnesota, were reviewed...

BACKGROUND: Acute convexity subarachnoid hemorrhage (cSAH) and cortical superficial siderosis (cSS) are neuroimaging markers of cerebral amyloid angiopathy (CAA) that may arise through similar mechanisms. We sought to compare the prevalence of cSS between patients with CAA presenting with acute cSAH versus lobar intracerebral hemorrhage (ICH), and to explore the physiopathology of cSS by examining neuroimaging associations. METHODS: We retrospectively analyzed data from 116 consecutive patients with probable CAA (mean age, 77...

BACKGROUND: Non-traumatic, spontaneous subarachnoid hemorrhage occurs in approximately 85% of cases where there is a ruptured saccular aneurysm. An additional 10% of cases arise from non-aneurysmal peri-mesencephalic hemorrhages. CASE PRESENTATION: We report a rare case of a young female, with underlying Evans syndrome, who was initially thought to have non-hemorrhagic stroke, eventually diagnosed having isolated non-traumatic, non-aneurysmal convexal subarachnoid haemorrhage...

BACKGROUND: Non-traumatic convexity subarachnoid hemorrhage (cSAH) is a rarely reported condition with a wide spectrum of etiologies. Cerebral ischemia secondary to extracranial or intracranial atherosclerotic disease has been identified as a relatively uncommon cause of cSAH. CASE REPORT: We report a case of cSAH caused by cardioembolic stroke. A 69-year old female patient developed suddenly left-sided face and body weakness and numbness and visual neglect on the left...

PURPOSE: The cortical bridging venous segment protruding into the inner skull depression (CBVISD), a distinctive structure found in the calvarial convexity, may be a potential risk factor for hemorrhagic complications resulting from trephination. However, this subject has not been documented. In the present study, we explore the CBVISD using magnetic resonance imaging (MRI). METHODS: A total of 94 patients underwent contrast-enhanced MRI. Distributions of the CBVISDs were recorded in two symmetrical regions of the frontal calvarial convexity...

An 83 year-old-man with left atrial appendage occluder (LAAO) developed Pseudomonas Aeruginosa (PA) infective endocarditis. MRI at day 3 of onset showed distal small infarcts in both middle cerebral arteries and left postero-inferior cerebellar artery territories. MRI at day 6 revealed two sites of convexity subarachnoid hemorrhage (cSAH). MRA and CTA failed to reveal a Mycotic aneurysm. The radiologic findings favor the assumption of necrosis of distal branches of mca or of pial arteries wall. This case present three unusual features: the presence of localized cSAH after initiation of antibiotherapy without mycotic aneurysm being individualized; the late occurrence of infective endocarditis after LAAO implantation; the very rare occurrence of PA in prosthetic infections...

OBJECTIVES: Falls are commonly reported in children who present with both accidental and inflicted brain injuries. Short falls rarely result in serious or life-threatening injuries. Our purpose is to describe a series of cases of short falls with occipital impact leading to subdural hemorrhage (SDH). METHODS: We present a series of 8 witnessed accounts of young children diagnosed as having SDHs after striking the back of their heads during a short fall. Child-abuse physicians were surveyed to determine if they had evaluated a child younger than 24 months diagnosed as having SDH, with or without retinal hemorrhages, following a witnessed fall with occipital impact...

PURPOSE: To report a case of anterior sacral meningocele with intralesional bleeding secondary to sacrococcygeal trauma. Likewise, there is a discussion about the physiopathology and the surgical approach to these types of lesions. METHODS: A 43-year-old man diagnosed with Marfan syndrome suffered sacrococcygeal trauma. He was admitted to the emergency room due to symptoms of headache, nausea, and lower limb subjective weakness. CT and MRI showed a large retroperitoneal mass with hemorrhagic content close to the sacrum...

We report the first case of severe fever with thrombocytopenia syndrome (SFTS) and a spontaneous acute subdural hematoma (SDH) in Korea. A 79-year-old male presented with fever and thrombocytopenia. On the third day of hospitalization, his mental changed from drowsy to semi-coma. Brain computed tomography indicated an acute subdural hemorrhage on the right convexity. He was given early decompressive craniectomy, but did not survive. Real-time reverse transcription polymerase chain reaction analysis of a blood sample indicated the presence of SFTS virus (SFTSV)...

Reversible cerebral vasoconstriction syndrome (RCVS) is a cerebrovascular syndrome characterized by multi-segmental constrictions of the cerebral arteries that resolves spontaneously within 3 months. Although RCVS is considered to be due to transient dysregulation of vascular tone, the exact pathomechanism remains unclear. We describe the case of a 15-year-old girl with RCVS induced by tacrolimus, who developed generalized seizure during the postoperative course of orthotropic heart transplantation. Magnetic resonance imaging at symptom onset showed a few vasoconstrictions accompanying brain edema and convexity subarachnoid hemorrhage...

The presence of hemosiderin in the optic nerve sheath and/or retina is sometimes used to estimate the timing of injury in infants or children with suspected non-accidental head trauma. To determine the prevalence of hemosiderin in deaths not associated with trauma, we performed a prospective study of retroocular orbital tissue, cranial convexity, and cervical spinal cord dura mater in infants and children <2.5 years age. In 53 cases of non-traumatic death, approximately 70% had blood or hemosiderin within the orbital fat, ocular muscles, and parasagittal cranial and/or cervical spinal subdural compartment...

A 51-year-old man showed hemiplegia on his right side after a traumatic brain injury (TBI). On initial brain computed tomography (CT) scan, an acute subdural hemorrhage in the right cerebral convexity and severe degrees of midline shifting and subfalcine herniation to the left side were evident. On follow-up brain magnetic resonance imaging (MRI), there were multiple microhemorrhages in the left parietal and occipital subcortical regions. To explain the occurrence of right hemiplegia after brain damage which dominantly on the right side of brain, we used diffusion tensor imaging (DTI) to reconstruct the corticospinal tract (CST), which showed nearly complete injury on the left CST...

BACKGROUND: Changes in head position are thought to cause a degree of brain shift in the intracranial cavity. However, little is known on the concurrent shift of the cerebral veins. The present study aimed to investigate the positional shift of the cerebral veins that accompanies brain shift. METHODS: Sagittal T2-weighted magnetic resonance imaging was performed on 21 consecutive patients lying in the supine and prone positions, using the same sequence. For each patient, imaging data were obtained for the two positions as a pair of images with morphologically best-matched cerebral contours...

Preterm neonates with a very low birth weight of less than 1,500 grams are at increased risk for developing intraventricular hemorrhage (IVH), which is a major cause of brain injury in preterm neonates. Quantitative measurements of ventricular dilatation or shrinkage play an important role in monitoring patients and evaluating treatment options. 3D ultrasound (US) has been developed to monitor ventricle volume as a biomarker for ventricular changes. However, ventricle volume as a global indicator does not allow for precise analysis of local ventricular changes, which could be linked to specific neurological problems often seen in the patient population later in life...
