The case of "isodense" subdural hematoma reported by Boyko et al (1) is interesting for the diffuse enhancement of the subdural hematoma, and for the discussion that accompanies it. It appears inappropriate, however, for Figure 1A and 1B to be published with the legend which states that there was no "identifiable extracerebral fluid collection." With modern CT scanners and good technique, the "...

Traumatic spinal subdural hematoma associated with intracranial subdural hematoma is a rare condition. Herein, we report the case of a 62-year-old man with lower back pain, radiating pain, and numbness in both lower extremities, without motor weakness, for 2 weeks. Lumbar magnetic resonance imaging (MRI) revealed high signal intensity on T1-weighted image (WI), and low signal intensity on T2-WI...

A case is reported of a Japanese female in whom acute right subdural hematoma due to the spontaneous rupture of the posterior branch of the right central artery occurred shortly after the onset of hypertensive subcortical hemorrhage of the right occipital lobe. Marked hypertension persisted. There was no evidence of subdural hematoma when a small collection of extravasated contrast medium from ...

Arachnoid cyst of the brain is common in children but its association with spontaneous subdural hygroma is rare. A case of a nine-year-old boy, without any preceding history of trauma, is presented here who came to the emergency department of a tertiary care hospital with complaints of headache, nausea, and vomiting for the last two weeks but more for the last two days. Examination showed a you...

BACKGROUND Spontaneous intracranial hypotension (SIH) is characterised by postural headache and low opening pressure at lumbar puncture without obvious cause. Cranial magnetic resonance imaging often shows small subdural collections without mass effect, dural enhancement, venous sinus dilatation, or downward displacement of the brain. The condition is thought to be benign. OBJECTIVES To evalu...

Intracranial subdural hematoma developing following spinal anesthesia is a rare but serious complication. We describe a case of subdural hematoma developing following spinal anesthesia and diagnosed late. A female patient receiving spinal anesthesia for cesarean delivery 45 days prior to arrival at the emergency department presented to our hospital with non-severe headache persisting for 45 day...

PURPOSE To determine if the position of the superficial cerebral cortical veins can be used to distinguish subdural hygroma from atrophy on MR brain scans. METHODS Retrospective review of MR scans obtained in cases of extracerebral fluid collections, separating these into two groups, ie, subdural hygroma or atrophy. FINDINGS All cases of atrophy in this study showed cortical veins and their...

Low-molecular-weight heparins, such as enoxaparin, are often used to treat thrombosis in infants. We present 4 infants with diffuse brain injury who developed cerebral venous sinus thrombosis or deep vein thrombosis and were treated with enoxaparin. These infants subsequently developed subdural hemorrhages, and enoxaparin was stopped. In 3 cases, the subdural hemorrhages were found on routine s...

Streptococcus bovis is an uncommon cause of meningitis and subdural empyema. We report one case each of meningitis and subdural empyema in which S. bovis biotype II was isolated from both the spinal fluid and blood. In one case, the organisms were seen on a gram-stained preparation of cerebrospinal fluid. The first patient presented with gastrointestinal symptoms of unknown etiology, was immuno...

Most physicians take the presence of a subdural hema-toma in a child without a history of trauma as presump-tive evidence of abuse. This assumption rests on our understanding of the pathophysiology of subdural hemorrhage ; subdural hematomas are caused by tearing intra-cranial bridging veins and it requires substantial force to rupture the veins and cause bleeding. The force required is thought...
