1/3. 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 = brain (Clic here for more details about this article) |
2/3. 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 = 850.3713307647keywords = haemorrhage (Clic here for more details about this article) |
3/3. 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 = 1177.4413776951keywords = intracranial haemorrhage, haemorrhage (Clic here for more details about this article) |
