1/293. A case of amnestic syndrome caused by a subcortical haematoma in the right occipital lobe.

    A case of an amnestic syndrome caused by a subcortical haematoma in the right occipital lobe is reported. A 62-year-old right-handed man presented with a sudden onset of headache to the hospital. On admission, he had a left homonymous hemianopsia, disorientation and recent memory disturbance, but had normal remote memory and digit span. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a subcortical haematoma in the right occipital lobe. These findings suggest that the patient's amnesia was caused by a lesion of the retrosplenial region in the non-dominant hemisphere.

2/293. Spontaneous cervical hematoma: a report of two cases.

    Cervical hematomas are generally associated with trauma, surgery, and tumors. Although they are rare, they can be life-threatening because they put the patient at risk for great-vessel compression and upper airway obstruction. We describe two cases of spontaneous cervical hematoma--one in an 81-year-old man and the other in a 30-year-old woman. The man reported dysphonia, dysphagia, and neck swelling of 5 hours' duration. He had been taking 100 mg/day of aspirin for a cardiovascular condition. Examination revealed that the man had polycythemia vera. The woman was found to have neck ache, odynophagia, and cervical ecchymosis; portal hypertension, schistosomiasis, and blood dyscrasia were also found. Both patients denied trauma. A suspected diagnosis of cervical hematoma was confirmed by computed tomography, and treatment was instituted. The hematomas resolved in about 2 weeks. The treatment of cervical hematoma is controversial, although it is agreed that the evaluation of upper airway obstruction and its permeability is mandatory. Surgical treatment is generally reserved for complicated cases because of the risk of infection or bleeding.

3/293. The diagnosis of subcapsular hematoma of the liver by scintigraphy.

    The diagnosis of subcapsular hematoma of the liver following blunt abdominal trauma has assumed clinical importance with recent reports of improved mortality with conservative management. There is increasing use of hepatic scintigraphy in evaluation of upper abdominal trauma. Two recently observed cases are used to illustrate the typical findings in this entity.

4/293. Laparoscopic drainage of an intramural duodenal hematoma.

    A 21-year-old man was admitted with vomiting and abdominal pain 3 days after sustaining blunt abdominal trauma by being tackled in a game of American football. A diagnosis of intramural hematoma of the duodenum was made using computed tomography and upper gastrointestinal tract contrast radiography. The hematoma caused obstructive jaundice by compressing the common bile duct. The contents of the hematoma were laparoscopically drained. A small perforation was then found in the duodenal wall. The patient underwent laparotomy and repair of the injury. Laparoscopic surgery can be used as definitive therapy in this type of abdominal trauma.

5/293. meningioma presenting as tolosa-hunt syndrome.

    A 23-year-old woman was admitted with headache, nausea, vomiting and blurred vision on the left side. Neurological examination showed ptosis with a complete internal and external ophthalmoplegia and a red fullness around the left orbita. Computed tomographic scanning of the brain revealed no abnormalities. As she improved on high doses of steroids a diagnosis of tolosa-hunt syndrome (THS) seemed to be indicated. However, magnetic resonance imaging (MRI) showed a lesion with intermediate signal intensity in the left cavernous sinus. craniotomy was performed when symptoms of THS recurred. Histopathological examination revealed a meningioma with a papillary aspect and some mitoses. This case illustrates that: (1) THS is still a diagnosis by exclusion; (2) MRI and histopathological examination are important if there is any doubt about the diagnosis; and (3) also when there is no doubt, improvement after steroid therapy may be a diagnostic pitfall. Therefore, not only MRI but also orbital phlebography and angiography should seriously be considered.

6/293. Sonographic diagnosis of mesenteric hematoma.

    Blunt abdominal trauma is common in children. Handlebar injuries may produce duodenal hematoma and pancreatic injuries, but mesenteric hematoma is relatively uncommon. We report a mesenteric hematoma resulting from a handlebar injury in a 4-year-old boy. Abdominal sonography showed a heterogeneous hypoechoic mass with an echogenic wall in the central portion of the abdomen. color Doppler study revealed vascularity at the periphery of the lesion, suggesting mesenteric hematoma. CT, upper gastrointestinal endoscopy, and a small bowel x-ray series confirmed the diagnosis.

7/293. Massive subependymal hemorrhage caused by an occult vascular malformation--two case reports.

    Two patients presented with massive subependymal hemorrhage caused by vascular anomalies occult to angiography, computed tomography (CT) scanning, and magnetic resonance (MR) imaging. A 47-year-old male initially presented with a headache and became comatose 3 weeks later. CT and MR imaging demonstrated a massive hematoma in the right caudate head projecting into the lateral ventricle. A 60-year-old male sustained heaviness of his left extremities 8 days prior to admission and his condition gradually deteriorated. neuroimaging revealed a right thalamic hematoma adjacent to the lateral ventricle. cerebral angiography, CT, and MR imaging failed to detect any vascular anomaly. The hematomas increased in size gradually and were surgically explored. The histological diagnosis was arteriovenous malformation for the first case and cavernous angioma for the second case that had ruptured repeatedly. These cases were unique in the unusual location in the subependyma, and diagnostic neuroimaging modalities could not disclose the vascular anomalies, and the hematomas enlarged progressively to become critically symptomatic. Surgical intervention is mandatory for mass reduction and correct diagnosis of such lesions, with favorable outcome as long as the surgery is not delayed until too late.

8/293. Extradural haematoma complicating lumbar puncture following a craniotomy. A case report.

    BACKGROUND: This case report illustrates the development of an intracranial extradural haematoma (EDH) as an uncommon complication of a lumbar puncture. CLINICAL PRESENTATION: A 10-year-old girl operated for intra-third ventricular cysticercosis developed postlumbar puncture headache after a drainage lumbar puncture (LP) on the 7th postoperative day. CT scan revealed a right frontal EDH away from the operative site. INTERVENTION: The child was managed conservatively in view of her preserved sensorium. RESULTS: The child had an uneventful recovery. Follow-up CT scans showed resolution of the haematoma. CONCLUSIONS: LP, though considered to be a safe procedure, may rarely be associated with a potentially lethal intracranial haematoma, which can be managed successfully if diagnosed at an early stage.

9/293. Early rebleeding from intracranial dural arteriovenous fistulas: report of 20 cases and review of the literature.

    OBJECT: In this study the authors sought to estimate the frequency, seriousness, and delay of rebleeding in a homogeneous series of 20 patients whom they treated between May 1987 and May 1997 for arteriovenous fistulas (AVFs) that were revealed by intracranial hemorrhage (ICH). The natural history of intracranial dural AVFs remains obscure. In many studies attempts have been made to evaluate the risk of spontaneous hemorrhage, especially as a function of the pattern of venous drainage: a higher occurrence of bleeding was reported in AVFs with retrograde cortical venous drainage, with an overall estimated rate of 1.8% per year in the largest series in the literature. However, very few studies have been designed to establish the risk of rebleeding, an omission that the authors seek to remedy. methods: Presenting symptoms in the 20 patients (17 men and three women, mean age 54 years) were acute headache in 12 patients (60%), acute neurological deficit in eight (40%), loss of consciousness in five (25%), and generalized seizures in one (5%). Results of the clinical examination were normal in five patients and demonstrated a neurological deficit in 12 and coma in three. Computerized tomography scanning revealed intracranial bleeding in all cases (15 intraparenchymal hematomas, three subarachnoid hemorrhages, and two subdural hematomas). A diagnosis of AVF was made with the aid of angiographic studies in 19 patients, whereas it was a perioperative discovery in the remaining patient. There were 12 Type III and eight Type IV AVFs according to the revised classification of Djindjian and Merland, which meant that all AVFs in this study had retrograde cortical venous drainage. The mean duration between the first hemorrhage and treatment was 20 days. Seven patients (35%) presented with acute worsening during this delay due to radiologically proven early rebleeding. Treatment consisted of surgery alone in 10 patients, combined embolization and surgery in eight, embolization only in one, and stereotactic radiosurgery in one. Three patients died, one worsened, and in 16 (80%) neurological status improved, with 15 of 16 AVFs totally occluded on repeated angiographic studies (median follow up 10 months). CONCLUSIONS: The authors found that AVFs with retrograde cortical venous drainage present a high risk of early rebleeding (35% within 2 weeks after the first hemorrhage), with graver consequences than the first hemorrhage. They therefore advocate complete and early treatment in all cases of AVF with cortical venous drainage revealed by an ICH.

10/293. Rectus sheath hematoma.

    We describe 3 patients with rectus sheath hematoma presenting to the emergency department. Prompt consideration of this uncommon cause of abdominal pain may prevent more expensive and invasive diagnostic tests and, in some cases, unnecessary hospitalization and laparotomy.
