1/50. Heading injury precipitating subdural hematoma associated with arachnoid cysts--two case reports.A 14-year-old boy and a 11-year-old boy presented with subdural hematomas as complications of preexisting arachnoid cysts in the middle cranial fossa, manifesting as symptoms of raised intracranial pressure. Both had a history of heading the ball in a soccer game about 7 weeks and 2 days before the symptom occurred. There was no other head trauma, so these cases could be described as "heading injury." arachnoid cysts in the middle cranial fossa are often associated with subdural hematomas. We emphasize that mild trauma such as heading of the ball in a soccer game may cause subdural hematomas in patients with arachnoid cysts.- - - - - - - - - - ranking = 1keywords = subdural (Clic here for more details about this article) |
2/50. Intracystic hemorrhage of the middle fossa arachnoid cyst and subdural hematoma caused by ruptured middle cerebral artery aneurysm.We report a case of a cerebral aneurysm arising from the bifurcation of the left middle cerebral artery that ruptured into a left middle cranial fossa arachnoid cyst, associated with acute subdural hematoma. We discuss the relationships of aneurysm, arachnoid cyst, and subdural hematoma.- - - - - - - - - - ranking = 0.85714285714286keywords = subdural (Clic here for more details about this article) |
3/50. role of MR imaging in the diagnosis of complicated arachnoid cyst.BACKGROUND: arachnoid cysts are intra-arachnoidal cerebrospinal fluid collections that are usually asymptomatic, however, they may become acutely symptomatic due to enlargement of the cyst or the presence of hemorrhage. MATERIALS AND methods: We report a case of a child presenting with a 3-week history of headaches, nausea, and vision problems. There was no history of trauma. MRI clearly demonstrated a left middle cranial fossa arachnoid cyst with associated subacute intracystic and subdural hematoma that was causing mass effect and required surgery. RESULTS: This lesion was isodense to the brain on CT. CONCLUSION: We focus on the importance of MR imaging in the differentiation of these subacute/early chronic hemorrhagic collections that may be overlooked with CT.- - - - - - - - - - ranking = 0.14285714285714keywords = subdural (Clic here for more details about this article) |
4/50. Arachnoid cyst rupture with concurrent subdural hygroma.arachnoid cysts (ACs) are relatively common intracranial mass lesions, which occur most often in the middle cranial fossa. While these lesions can present as a mass lesion, many are asymptomatic. Rarely, posttraumatic or spontaneous rupture of ACs can result in intracystic hemorrhage, subdural hematoma or subdural hygroma. We have encountered two cases of ruptured arachnoid cysts that resulted in subdural hygromas. Both patients harbored middle cranial fossa cysts and suffered mild closed head injuries. The presentation, radiographic findings and surgical management of these patients as well as the association between ACs and subdural hygromas are described.- - - - - - - - - - ranking = 1.1428571428571keywords = subdural (Clic here for more details about this article) |
5/50. Arachnoid cyst with spontaneous rupture into the subdural space.Spontaneous rupture of an arachnoid cyst into the subdural space is an unusual complication. Only six cases have been reported in the literature. We report here an additional case and review the literature concerning arachnoid cysts. The possible pathogenesis of this condition is discussed.- - - - - - - - - - ranking = 0.71428571428571keywords = subdural (Clic here for more details about this article) |

7/50. Interhemispheric cyst causing leg monoparesis in the elderly--case report.A 64-year-old female presented with a rare case of interhemispheric cerebral cyst manifesting as progressive monoparesis in the right lower extremity for 2 years. Surgical excision of the cyst wall was performed and communication to the subdural space was created. Postoperatively, the cyst was greatly reduced in size, and the neurological signs and symptoms were markedly improved. Interhemispheric cyst often presents with motor disturbances such as hemisparesis or paraparesis. These symptoms tend to progress slowly and sometimes years are required for a proper diagnosis. Interhemispheric cyst can also cause slowly progressive monoparesis in the lower extremity.- - - - - - - - - - ranking = 0.14285714285714keywords = subdural (Clic here for more details about this article) |
8/50. Chronic subdural hematoma complicating arachnoid cyst secondary to soccer-related head injury: case report.OBJECTIVE AND IMPORTANCE: soccer has become a popular sport, with more than 200 million Federation International football association-registered soccer players worldwide and 16 million participants in the united states. The risk of sustaining a significant head injury from a strike to a soccer ball with the head is unknown, but it may be increased with the presence of an underlying congenital arachnoid cyst. CLINICAL PRESENTATION: We describe the case of a 16-year-old female patient who sustained a large chronic and subacute subdural hematoma without a loss of consciousness from being struck on the head by a soccer ball. Because of the large size of the hematoma and her contralateral symptoms, surgery was performed. INTERVENTION: A temporal craniotomy for evacuation of a large chronic and subacute subdural hematoma with removal and fenestration of the arachnoid cyst resulted in resolution of her symptoms. Rigid craniotomy fixation of this small operative flap should allow the patient to return to soccer participation in the future. CONCLUSION: Although many may not consider soccer a contact sport, recent epidemiological data suggest that it is a common cause of sports-related concussion. In addition, as our case report demonstrates, there is a risk of significant intracranial injury and hematoma formation subsequent to a strike on the head by a soccer ball, and arachnoid cysts may contribute an additional risk of head injury.- - - - - - - - - - ranking = 0.85714285714286keywords = subdural (Clic here for more details about this article) |
9/50. Temporal lobe epilepsy associated with hippocampal sclerosis and a contralateral middle fossa arachnoid cyst.We report on a 13-year-old boy with temporal lobe epilepsy associated with left hippocampal sclerosis and a contralateral arachnoid cyst in the middle cranial fossa (ACMCF). Chronic intracranial recording from subdural grid electrodes showed the left medial temporal lobe to be the ictal onset zone. After left anterior temporal lobectomy with hippocampectomy, seizure control was improved. ACMCF was not considered the direct cause of epilepsy; instead the seizures were attributed to hippocampal sclerosis.- - - - - - - - - - ranking = 0.14285714285714keywords = subdural (Clic here for more details about this article) |
10/50. Haemorrhage into an arachnoid cyst: a serious complication of minor head trauma.arachnoid cysts are infra-arachnoidal cerebrospinal fluid collections that are usually asymptomatic. However, they can become acutely symptomatic because of haemorrhage and cyst enlargement, which may result from minor head trauma. The range of symptoms is wide and many are "soft" signs. diagnosis is important as cysts causing mass effect require surgery. A case is reported of a child presenting with localised headaches after minor head trauma. Computed tomography demonstrated an arachnoid cyst with evidence of haemorrhage, which required surgical intervention. Other cases of arachnoid cyst presenting to our hospital or reported in the literature are reviewed with respect to presenting symptoms and signs. Localised headaches, behavioural or cognitive changes and ataxia are more commonly associated with this disorder than nausea, vomiting, visual disturbances or seizures. This range of symptomatology following minor head trauma may warrant computed tomography when other criteria for this investigation are not met.- - - - - - - - - - ranking = 0.00071074906932941keywords = haemorrhage (Clic here for more details about this article) |
