subdural hygroma vs atrophy

They accumulate in the subdural space around the convexity of the brain – normally a … Chronic subdural hematoma: the closest differential which is usually unilateral and asymmetrical if bilateral. Acute CSF subdural hygromas had signal intensities identical to CSF without MR evidence of blood products. Among neurotraumatologists it is generally known that SDHys usually derive from head injuries and represent rare posttraumatic complications that may coexist with epidural or subdural hematomas. When a subdural hygroma is seen in infants and children it is often after they have had an infection but it could also be from a minor head injury from falling, hitting their head, or even child abuse. Cat and dog models suggest that, once the dura and arachnoid separate, fibrin, from either serum or exudates, can induce proliferation of granulation tissue on the inner dural surface [ 19 ]. Approximately one-third of patients with CSDH have a history of minor trauma, and risk factors other than brain atrophy and subdural hygroma are old age, chronic alcohol addiction, blood coagulation disorders, anticoagulant use, and epilepsy. Cerebral cortical atrophy: In atrophy, subarachnoid space is widened, the cortical veins traversing widened CSF spaces over cerebral convexities favours atrophy best seen on post contrast T1 MRI. Subdural hygromas are the collections of clear fluid containing mostly CSF. MR imaging, with its unique ability to delineate the various phases of hemorrhage, is well suited to the evaluation of subdural hemorrhage. However, they should be considered in patients after spinal anesthesia with continuing orthostatic headache, especially if contributing factors are present, such as a ventriculo-peritoneal shunt or brain atrophy … 33,42,43,57 ⇓ ⇓ –60 Unfortunately, the causes of SDHys cannot always be read directly from the CT or MR images. Patients with brain atrophy and repeated subdural hemorrhages can develop subdural hygromas. Objective: Brain atrophy and subdural hygroma were well known factors that enlarge the subdural space, which induced formation of chronic subdural hematoma (CSDH). Key Words: Magnetic resonance imaging․Subdural hygroma․Atrophy․Subarachnoid space․Diagnosis INTRODUCTION Extracerebral or pericerebral fluid collection includes subdural hygroma17,25,26), subdural effusion10,12,18), enlargement of the subara- The Pathogenesis of Subdural Hygromas: An Ongoing Odyssey. In our study, 50% of our traumatic subudural hygroma patients were between 16 and 40 years; this characterizes a younger and prevalent population. Post-traumatic subdural hygroma it is an intracranial lesion, commonly misdiagnosed due to its unclear symptomatology and slow progression. Symptoms. At surgery, clear fluid under pressure was found. 2. Conclusion: The cortical vein sign is not useful to differentiate subdural hygroma and atrophy. For different authors subdural hygroma is more prevalent in older patients with some degree of cerebral atrophy 4,9,14,19.
