A case of coup and contrecoup extradural hematoma

An atypical case of head trauma with late onset of contrecoup epidural hematoma, cerebellar contusion, and cerebral infarction in the territory of the recurrent artery of Heubner

“…42 The dura mater of the lateral frontal lesion is easily detached from the inner table. [26][27][28][29][30][31] These anatomical mechanisms, together with coagulopathy, may have caused the contrecoup epidural hematoma in the present case.…”

“…[26][27][28][29][30][31] Nakamura reported that the negative pressure in the forehead caused by head injury in the occipital region was 1.6 times the occipital positive pressure, and that the dura of the frontal lobe was susceptible to dissection. 42 The dura mater of the lateral frontal lesion is easily detached from the inner table.…”

“…5,26-31 Only 7 cases have been reported. 5,[26][27][28][29][30][31] Four of the 7 patients underwent craniotomy for the contrecoup epidural hematoma. One patient died of posterior fossa contusion and hematoma despite having undergone an operation for coup injury.…”

Traumatic Coronal Suture Diastasis and Contre-Coup Epidural Hematoma

“…Only two other cases satisfied these criteria and they are summarized in the Table with our case for comparison, 12,13 with two further cases involving isolated contrecoup posterior fossa epidural hematoma after forehead impact. 14,15 Conversely, there are several other cases in association with association with coup epidural hematoma 16,17 , subdural hematoma 18 , or contusion 19,20 . In the two previously reported cases, no clear mechanism was found to underlie the development of these lesions.…”

Bilateral asynchronous acute epidural hematoma : a case report

“…Even rarer are cases where the hematomas develop sequentially, one after removal of the other [1,3,6,10,12,14,16-18,21,23,28,29]. Concerning the sporadic reports of such cases, the incidence rate of bilateral epidural hematomas are variable in various studies ranging from 0.5 to 10% of all epidural hematomas [4,9,11,20,28,29].…”
