Dear Editor, Acute subdural hematoma (ASDH) is a neurosurgical emergency. Interhemispheric acute subdural hematomas have been reported infrequently in the past. They are usually considered to be a distinct entity because of their unusual location and the fact that their management is still a matter of debate. The most common sites for ASDH are the fronto-parietal convexities and the middle cran...

RATIONALE Spontaneous spinal epidural hematoma (SSEH) is a relatively rare but potentially disabling disease, and the classical presentation of it includes an acute onset of severe, sometimes radiating back or neck pain, followed by signs and symptoms of rapidly evolving nerve root or spinal cord compression. PATIENT CONCERNS Here, we report a 26-year-old female patient presented with weaknes...

The occurrence of bilateral extradural hematomas is an uncommon consequence of craniocerebral trauma and its incidence is variable in various studies ranging from 2-25%.1 We studied all cases of head injury brought to our institute over a period of 6 months and found the incidence of bilateral extradural hematomas to be 13.3%.

Organized hematoma is a rare complication that can develop following gamma knife radiosurgery (GKS) for cerebral arteriovenous malformation (AVM). Here, we describe 5 patients with growing organized hematomas that developed from completely obliterated AVMs several years after GKS. The patients were 15, 16, 30, 36, and 38 years old at the time of GKS, respectively, and 3 patients were female. Fo...

The quality of hematomas are crucial for successful early bone defect healing, as the structure of fibrin clots can significantly influence the infiltration of cells, necessary for bone regeneration, from adjacent tissues into the fibrin network. This study investigated if there were structural differences between hematomas from normal and delayed healing bone defects and whether such differenc...

In a consecutive series of 30 hospitalized cervical injury patients, 18 proved to have widening of the prevertebral soft tissue space due to hematoma. The upper limit of normal width in 50 noninjury patients was used as a reference. Hematoma almost exclusively manifested at C1-C4 and proved to be closely related to fractures of anterior elements of the spine. Relatively small hematomas were enc...

This report describes 3 young male patients with multiple lumbar spondylolyses in combination with a symptomatic epidural hematoma. The records of all 3 patients were reviewed for clinical details. All patients were successfully treated without surgical intervention. Initial neuroimaging results for all patients revealed epidural hematomas, and follow-up imaging confirmed resolution of the hema...

BACKGROUND Little is known about the coagulation factors as predictors of cerebral bleeding in rt-PA thrombolysis. The aim of this study was to determine what early coagulation parameters could predict early hemorrhagic lesions. METHODS Consecutive patients were included in the Lyon rt-PA protocol. Early hematomas (within 24 hours), diagnosed on an anatomoradiological basis (symptomatic and n...

BACKGROUND AND PURPOSE Intracerebral hematoma may complicate treatment of acute myocardial infarction in patients treated with fibrinolytic agents. We studied the clinical presentation and computed tomographic characteristics. METHODS We studied eight patients with lobar intracerebral hematomas after fibrinolytic treatment of acute coronary occlusion. All patients had electrocardiographic and...
