A calvarial acute subdural hematoma migrating into the spinal canal in a young male

Commentary

“…The remaining blood clots as soon as will be spontaneously absorbed. [ 6 ] As in this case report, only laminectomy may be insufficient. (It was understood from radiological imaging such as hemilaminectomy or partial facetectomy.)…”

“…[ 5 ] It can pass into the anterior from posterolateral of spinal cord or it can occur from a traumatic vertebral body bleeding, or may be the bleeding caused due to the cervicothoracic junction may be replaced down by gravity. [ 6 ]…”

Prevention of Cerebral Herniation by Decompressive Craniotomy in a Child with Acute Peritentorial Subdural Hematoma and Brain Edema: A Case Report

“…It has been reported in a very limited number of studies in the literature that removal or reduction of the pressure on the temporal base has resulted in a motion in the subarachnoid space, together with the increased intracranial pressure, and that the cerebrospinal fluid has washed the blood on the tentorial surface and led to its distribution [7,8]. The blood on the tentorium may have migrated downward after being collected around the free edges of tentorium in the medial side [8]. The diffuse increase in the intracranial pressure of the case affecting all intracranial areas has prevented further migration of the peritentorial blood downward, and led to an increased pressure on the mesencephalon.…”

Cranial subdural migrating to lumbar subdural space in a toddler

“…However, idiopathic causes of spinal SDH have also been reported 3. Few studies have described the development of spinal SDH as a result of the migration of an intracranial SDH 2 4–8. The proposed mechanism of intracranial SDH resolution and SDH migration has been linked to elastic cerebral tissues as well as the anatomic continuity between the cranial and spinal subdural spaces 5 9.…”

“…Few studies have described the development of spinal SDH as a result of the migration of an intracranial SDH 2 4–8. The proposed mechanism of intracranial SDH resolution and SDH migration has been linked to elastic cerebral tissues as well as the anatomic continuity between the cranial and spinal subdural spaces 5 9. Combined with dilution with CSF from small arachnoid tears, the elasticity of the brain is thought to aid in the redistribution of the blood 4.…”
