OBJECTIVE The objective of this study was to test the hypothesis that midline (interhemispheric or perimesencephalic) traumatic subarachnoid hemorrhage (tSAH) on initial CT may implicate the same shearing mechanism that underlies severe diffuse axonal injury (DAI). METHODS The authors enrolled 270 consecutive patients (mean age [± SD] 43 ± 23.3 years) with a history of head trauma who had undergone initial CT within 24 hours and brain MRI within 30 days. Six initial CT findings, including intraventricular hemorrhage (IVH) and tSAH, were used as candidate predictors of DAI...

Small acute diffusion-weighted imaging (DWI) lesions can accompany intracerebral hemorrhage due to cerebral amyloid angiopathy (CAA). We therefore examined the occurrence of such lesions in the context of CAA-related convexal subarachnoid hemorrhage (cSAH) both in a cross-sectional and longitudinal manner. DWI lesions were noted in 14/29 (48%) patients at their index cSAH and 12/21 patients (57%) showed acute small DWI lesions at follow-up MRI. Forty-four of 71 (62%) DWI lesions were spatially related to areas of cortical superficial siderosis...

Background: Reversible cerebral vasoconstrictive syndrome (RCVS) has characteristic clinical features, brain imaging and Angiographic features. The majority of RCVS cases are associated with the use of antidepressants, polysubstance abuse, and nasal decongestants. We here present a case that highlights the use of eucalyptus herbs as a possible precipitant factor for RCVS formation. Case Presentation: A 42-year-old woman presented to the emergency department with a tingling sensation on the right-hand side of her body and a two-week progressive throbbing severe holocranial headache radiating to the neck, with associated nausea, photophobia, and phonophobia...

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 AND PURPOSE: Acute convexity subarachnoid hemorrhage (cSAH) and cortical superficial siderosis (cSS) are neuroimaging markers of cerebral amyloid angiopathy (CAA) that may arise through similar mechanisms. The prevalence of cSS in patients with CAA presenting with acute cSAH versus lobar intracerebral hemorrhage (ICH) was compared and the physiopathology of cSS was explored by examining neuroimaging associations. METHODS: 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...

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...
