1/5. Spontaneous development of bilateral subdural hematomas in an infant with benign infantile hydrocephalus: color Doppler assessment of vessels traversing extra-axial spaces.We present an infant with macrocrania, who initially demonstrated prominent extra-axial fluid collections on sonography of the brain, compatible with benign infantile hydrocephalus (BIH). Because of increasing macrocrania, a follow-up sonogram of the brain was performed; it revealed progressive enlargement of the extra-axial spaces, which now had echogenic debris. color Doppler US showed bridging veins traversing these extra-axial spaces, so it was initially thought that these spaces were subarachnoid in nature (positive cortical vein sign). However, an arachnoid membrane was identified superior to the cortex, and there was compression of true cortical vessels beneath this dural membrane. An MRI of the brain showed the extra-axial spaces to represent bilateral subdural hematomas. The pathogenesis of spontaneous development of the subdural hematomas, in the setting of BIH, is discussed. We also emphasize that visualizing traversing bridging veins through extra-axial spaces does not necessarily imply that these spaces are subarachnoid in origin.- - - - - - - - - - ranking = 1keywords = subarachnoid (Clic here for more details about this article) |
2/5. Acute intracranial subdural hematoma following a lumbar CSF leak caused by spine surgery.STUDY DESIGN: Case report. OBJECTIVE: To report a case of an acute intracranial subdural hematoma that formed due to cerebrospinal fluid (CSF) leak following lumbar surgery. SUMMARY OF BACKGROUND DATA: intracranial hypotension may occur when CSF is removed from the subarachnoid space. Intracranial subdural hematoma formation has been observed following significant CSF drainage during lumbar puncture or ventricular shunt placement. However, formation has been described only twice in the literature following spine surgery. methods: Retrospective review of the patient's medical record and head CT imaging. RESULTS: A 55-year-old woman underwent lumbar surgery for failed back syndrome. Intraoperatively, a dural tear was noted and repaired. One week later, she developed expressive aphasia, and CSF drainage from her lumbar wound was noted. A head CT revealed an acute intracranial subdural hematoma with mass effect. Evacuation of the hematoma occurred via craniotomy, and the lumbar dura was repaired intraoperatively. CONCLUSIONS: We report the rare case of an acute intracranial subdural hematoma caused by a CSF leak following lumbar surgery. This report illustrates the potential morbidity associated with CSF leaks occurring after spinal surgery.- - - - - - - - - - ranking = 0.5keywords = subarachnoid (Clic here for more details about this article) |
3/5. Subdural haemorrhage following endoscopic third ventriculostomy. A rare complication.Subdural collections or hematomas are frequently observed after shunt placement [7-9, 13], but rarely after ETV [6]. A review of literature revealed 7 cases [1, 5, 6, 10, 12], of which only 1 was symptomatic [5]. We will discuss the causes, management, and methods of prevention of this complication and we will present a case of symptomatic subdural haematoma, following endoscopic third ventriculostomy for illustration.- - - - - - - - - - ranking = 0.99390254704675keywords = haemorrhage (Clic here for more details about this article) |
4/5. The "Moya" you look, the "Moya" you find.A middle-aged woman was admitted to hospital after a motor vehicle accident. A large acute intracranial haematoma was initially thought to be traumatic in origin, but its unusual position and the lack of external features of head trauma prompted investigation for other causes of intracerebral haemorrhage. Moyamoya intracranial vascular abnormalities were diagnosed. We discuss the presentation of non-traumatic intracranial haemorrhage in the setting of presumed trauma, and the unusual conditions of moyamoya syndrome and moyamoya disease.- - - - - - - - - - ranking = 0.49695127352337keywords = haemorrhage (Clic here for more details about this article) |
5/5. Venous loop mimicking middle cerebral artery bifurcation aneurysm on computed tomographic angiography--case report.BACKGROUND: CT angiography has been widely used for the detection of cerebral aneurysm. However, there are still limitations despite improving CT angiographic techniques. We describe the unusual case of the detection of a false-positive aneurysm on CT angiography. CASE DESCRIPTION: A 64-year-old man presented with a 14-day history of severe headache and nuchal rigidity. brain CT demonstrated no subarachnoid hemorrhage, but cerebrospinal fluid appeared xanthochromic in 3 successive tubes after lumbar puncture. Subsequent CT angiography suggested an aneurysm at the bifurcation of the left MCA. However, at operation, prominent sylvian vein superimposed on the bifurcation of the left MCA, and there was no aneurysm. Follow-up monitoring with conventional angiography at 2 weeks showed no abnormal findings. The patient recovered uneventfully. CONCLUSION: The case demonstrates that although CT angiography has a reportedly high specificity and sensitivity for the detection of intracranial aneurysm, careful interpretation is required to diagnose intracranial aneurysms.- - - - - - - - - - ranking = 0.5keywords = subarachnoid (Clic here for more details about this article) |
