1/58. magnetic resonance imaging in acute non-accidental head injury.Making the diagnosis of non-accidental head injury, particularly in the acute illness, can be difficult. The aim of this retrospective study was to evaluate the use of magnetic resonance imaging in the acute presentation of non-accidental head injury. Twelve cases admitted to the Royal Hospital for Sick Children, Edinburgh with a diagnosis of non-accidental head injury, and who had magnetic resonance imaging in the acute illness, were identified. The average age was 5.7 mo (range 1 to 34 mo). The mechanism of the primary injury was whiplash-shaking injury syndrome with impact in four cases and without evidence of impact in seven; in one case there was a compression injury. The magnetic resonance imaging findings reflected the pathological consequences of rotational acceleration-deceleration injury and did not differ between those cases with evidence of impact and those without. Subdural haematomas were identified in all cases; the commonest location for subdural blood was the subtemporal region. It is surprising and important that the most frequent location of subdural blood was in the subtemporal area. This is an area difficult to assess by computerized tomography. Evidence of repeated injuries was found in two cases. These findings confirm the value of magnetic resonance imaging in the acute phase of non-accidental head injury.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
2/58. dissection of the middle cerebral artery caused by invasion of malignant glioma presenting as acute onset of hemiplegia.A 57-year-old, previously healthy man who developed acute onset of hemiplegia is presented. Neuro-imaging studies on admission suggested dissection of the middle cerebral artery producing infarction in the frontotemporal region. In contrast to his stable clinical course, serial neuro-imaging studies disclosed rapid growth of malignant glioma, which was confirmed at surgery. Microscopic examination of the surgical specimen demonstrated invasion of glioma cells into the arterial wall associated with intramural haematoma formation of the middle cerebral artery. This case is the first to document dissection of an intracranial artery caused by invasion of tumour cells.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
3/58. Haemorrhagic lumbar synovial cyst. A cause of acute radiculopathy.A total of 254 cases of synovial cysts of the spine have been reported in the English literature, but only eight have been associated with haemorrhage. We describe a 55-year-old man with acute radiculopathy resulting from haemorrhage involving a synovial cyst at a lumbar facet joint. Traumatic factors could have caused bleeding around or into the synovial cyst. Treatment by resection of the cyst and evacuation of the haematoma led to complete neurological recovery.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
4/58. Non-traumatic spinal extradural haematoma: magnetic resonance findings.Non-traumatic extradural spinal haematoma is an uncommon condition that is usually associated with a poor outcome. It may present acutely with signs and symptoms of major neurological dysfunction secondary to cord compression, or subacutely over a number of days or weeks with fluctuating symptoms. The exact aetiology of this condition is incompletely understood, but it is believed that the blood is venous in origin, as distinct from the arterial origin of intracranial extradural haematomas. Causes of non-traumatic extradural spinal haematoma include anticoagulation, vasculitis such as systemic lupus erythematosus (SLE), and spinal arteriovenous malformations. Conditions that may mimic an acute spinal haematoma include extradural abscess and extradural metastatic infiltration. It is important to make a diagnosis of extradural compression because surgery may offer the best hope in restoring neurological function in these patients. Imaging modalities used for the investigation of extradural haematomas include myelography, CT myelography (CTM) and MRI with or without gadolinium enhancement. The MR appearances of acute extradural abscess and extradural tumour can mimic an extradural haematoma. In subacute haematoma, owing to the magnetic properties of blood degradation products, MR is more specific in diagnosing and ageing of the haematoma.- - - - - - - - - - ranking = 12keywords = haematoma (Clic here for more details about this article) |
5/58. Tentorium cerebelli subdural haematoma complicating subarachnoid haemorrhage.Acute subdural haematoma (SDH) as a result of aneurysmal rupture is a rare event. We report a tentorium cerebelli SDH, secondary to a ruptured aneurysm which we believe is unique in the literature. This report also gives further support to the theory that a sentinel bleed causes inflammation and adhesion between the aneurysm and arachnoid as the underlying pathology in these unusual subdural haematomas. Since the first report of acute SDH from a ruptured aneurysm by Hasse in 1855, only about 150 further cases have been reported in the literature. We describe a further case, but at an as yet unreported site with radiological evidence of a sentinel bleed.- - - - - - - - - - ranking = 6keywords = haematoma (Clic here for more details about this article) |
6/58. [diagnosis and treatment of spleen rupture during pancreatitis]A 31-year old man was admitted for acute pancreatitis. His condition deteriorated progressively and he developed an acute anemia followed five days after admission by an hemorrhagic shock consecutive to splenic rupture. A 45-year old woman was admitted because of an acute episode of chronic pancreatitis. She improved progressively but developed eleven days after admission an hemorrhagic shock consecutive to the rupture of a subcapsular haematoma of the spleen. splenic rupture, an infrequent complication of acute or chronic pancreatitis, is responsible for anemia and hemorrhagic shock. Abdominal ultrasonography and CT scan are necessary to make the diagnosis of splenic rupture and to look for risk factors of splenic rupture, i.e. necrosis in the spleen hilium, left pancreatic pseudocyst, splenic vein thrombosis, segmental portal hypertension, splenomegaly and intrasplenic collection. When possible, embolization of the splenic artery can stop bleeding. splenectomy with distal pancreatectomy seems to be the appropriate treatment of splenic rupture.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
7/58. Iatrogenic acute subdural hematoma due to drainage catheter.BACKGROUND: Insertion of a catheter for drainage of a cavity is a routine step in many surgical practices. In neurosurgery, catheters are commonly placed in the subdural, subgaleal, or epidural spaces to prevent haematoma formation. CASE DESCRIPTION: We present three cases of iatrogenic acute subdural hematoma. These were all related to the drainage catheters. In the first case, a subgaleal redivac suction catheter was used after craniotomy for brain abscess. The other two patients had ordinary ventricular catheters placed in the subdural space after burr hole drainage of chronic subdural hematoma. The drainage catheter was removed on postoperative day 5 in the first case and two days after the initial operation in the other two cases. Shortly after the removal of the drains, the conditions of the patients deteriorated rapidly due to the development of acute subdural hematoma. CONCLUSION: Although they are extremely uncommon, life-threatening complications related to a drainage catheter are a real possibility. Therefore, the procedure should not be taken lightly.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
8/58. Acute type A aortic dissection involving the left main coronary artery and the aortic valve--a case report.The authors report a case study of a 60 year-old-male admitted to the Coronary Care Unit with severe chest pain, hypertension and ST depression on the anterior and lateral leads of the electrocardiogram. A diastolic murmur was heard in the aortic area. The chest X-ray showed an enlarged superior mediastinum. The transthoracic echocardiogram revealed an image that indicated an intimal flap above the aortic plane with severe aortic regurgitation. An aortography was performed and confirmed the diagnosis of acute type A aortic dissection with partial obstruction of the left main coronary artery, probably due to compression by the haematoma. The patient underwent emergency surgical repair with replacement of the aortic valve and ascending aorta. The patient survived without complications post surgery and was discharged ten days after onset of symptoms. Twenty months later, the patient was asymptomatic and the transesophageal echocardiogram showed a dissection of the descending thoracic aorta, mild aortic regurgitation and good left ventricular systolic function.- - - - - - - - - - ranking = 1keywords = haematoma (Clic here for more details about this article) |
9/58. Acute spontaneous spinal epidural haematoma in a child.Spontaneous spinal epidural haematomas rarely occur. patients tend to be in their sixties or seventies. Acute spontaneous spinal epidural haematomas in children without a predisposition for bleeding disorders, trauma, vascular malformations or anticoagulant therapy have seldom been described. We present a case of a 4-year-old girl with a spontaneous cervical epidural haematoma diagnosed with MR.- - - - - - - - - - ranking = 7keywords = haematoma (Clic here for more details about this article) |
10/58. Widespread post-traumatic acute spinal subdural haematoma: case report and review of the literature.STUDY DESIGN: A case report of acute post-traumatic spinal subdural haematoma (ASSH). OBJECTIVE: To report a rare post-traumatic problem. SETTING: Dicle University Hospital, Diyarbakir, turkey. METHOD: A 3-year-old boy was admitted to our clinic with paraplegia 24 h after falling from a height of about 5 meters. Investigation revealed an acute spinal subdural haematoma. RESULTS: Following surgery there was marked improvement. The rehabilitation of the patient continues. CONCLUSION: MRI is the most valuable diagnostic method. In each case diagnosed as ASSH, prompt evacuation should be performed before irreversible neurological damage occurs.- - - - - - - - - - ranking = 6keywords = haematoma (Clic here for more details about this article) |
