A case of ruptured distal anterior cerebral artery aneurysm presenting with diagnostic dyspraxia is presented. A 54-year-old female was referred to our hospital with the complaint of sudden onset of headache followed by disturbance of consciousness. CT and MRI revealed subarachnoid hemorrhage with hematomas in the interhemispheric fissure and the supracallosal area, and CAG revealed a left-sided callosomarginal artery aneurysm. During and after hospitalization, she showed diagnostic dyspraxia characterized by behavior of both her hands opposite to what might be expected e.g. when she tried to pick up a bowl, both her hands moved forward and held it at once; she wiped her head and face with toilet paper after urination. At times her hands behaved in opposite ways. For example, while folding cloths, her right hand tended to fold them while the left hand tended to unfold them; when she put on a sweater, as the right hand put it on, the left hand took it off; when she put her shirt into her trousers, one hand pushed it in while the other hand pulled it out. This unusual behavior was considered to be caused by the impairment of the corpus callosum due to compression by the hematoma. It disappeared gradually over a period of one year. Involuntary motor behavior of the left hand while the right hand is in voluntary action is known as diagnostic dyspraxia. Although this symptom has rarely been reported so far in cases of ruptured distal anterior cerebral artery, it may become noticed more frequently through careful observation.

Two cases of ruptured distal anterior cerebral-artery aneurysms presenting with acute subdural hematoma are reported. Case 1 was a 55-year-old male, who showed abrupt disturbance of consciousness. An emergency CT revealed acute subdural hematoma at the right parietal convexity and interhemispheric fissure with moderate midline shift. There was no evidence of subarachnoid hemorrhage. Right carotid angiography showed an aneurysm at the right distal anterior cerebral artery. An emergency external decompression was performed and the aneurysm was clipped successfully through the interhemispheric fissure. In the operative field, subarachnoid hemorrhage could not been seen, and the patient had uneventful recovery. Case 2 was a 66-year-old female, who complained of severe headache. She deteriorated rapidly and become comatous with development of anisocoria. An emergency CT revealed acute subdural hematoma on the bilateral parietal convexities and interhemispheric fissure with severe midline shift. There was no evidence of subarachnoid hemorrhage. Carotid angiography showed right distal anterior cerebral artery aneurysm. An emergency external decompression was performed, then the aneurysm was clipped successfully. She recovered with disorientation and hemiparesis. Ruptured distal anterior cerebral artery aneurysms presenting with acute subdural hematoma without subarachnoid hemorrhage are rare. It is suggested that CT scans and history of patients are most important but an emergency angiography was prerequisite for correct diagnosis. Surgical treatment should be the best management in such cases.

A 78-year-old female with a prior history of migraine and mild hypertension presented to the emergency room with severe headache and mild meningism. The patient had transient significant reactive lymphocytosis, and a computed tomography scan of the head followed by a cerebral angiogram revealed an acute right-sided middle cerebral artery aneurysm rupture. This case illustrates that acute changes in the peripheral blood smear may suggest a more sinister cause for the presentation such as that of a ruptured middle cerebral artery aneurysm, particularly when multiple etiology for the presentation is possible.

A 64-year-old female came to our department because of a sudden onset of bilateral deafness 2 days before. She had sudden onset of mild headache, nausea and vomiting 9 days before, but was diagnosed as food poisoning by her home doctor. Her symptoms disappeared on the following day. Neurological examination revealed bilateral deafness, right facial palsy of central type and very slight neck stiffness. CT showed inconspicuous subarachnoid hemorrhage, but lumber puncture revealed definite subarachnoid hemorrhage. Another important finding of CT was old left temporal lobe infarction. Cerebral angiography detected right middle cerebral artery aneurysm at the trifurcation and moderate cerebral vasospasm of the right M2 portion. Neck clipping was successfully performed, but small size of right temporal lobe infarction was found on postoperative CT, which was due to cerebral vasospasm. Postoperative MRI showed bilateral temporal lobe infarction, especially including bilateral auditory cortex. This finding suggests that her deafness was cortical in origin.

A 51-year-old woman presented with a distal anterior cerebral artery aneurysm (DACAA) manifesting as severe headache and monoparesis of the left lower limb. Computed tomography revealed subarachnoid hemorrhage in the interhemispheric fissure, bilateral sylvian fissures, and basal cistern, and a hematoma in the supracallosal region. Angiography showed a large aneurysm (23 x 18 mm) located on the distal end of the azygos anterior cerebral artery (azygos ACA) at the supracallosal portion. T2-weighted magnetic resonance imaging demonstrated the hematoma as a mixed intensity mass, compressing the corpus callosum downward, and the aneurysm as a flow void anterior to the hematoma. Unilateral frontoparietal parasagittal craniotomy was performed with a horse-shoe shaped incision. The aneurysm was clipped via the interhemispheric approach, and the hematoma was aspirated. Postoperative angiography showed disappearance of the aneurysm and intact azygos ACA. The patient was discharged with mild monoparesis, paresthesia of the left lower limb and diagnostic dyspraxia. DACAA almost always arises at or near the genu of the corpus callosum and is often associated with vascular anomaly. In the literature, 22 of 26 cases of large and giant DACAA were located at or near the genu, but only 3 cases, including ours, in the supracallosal area. 11 cases were associated with azygos ACA. Therefore, hemodynamic stress caused by vascular anomaly may be involved in the formation of large or giant DACAA in contrast with cases of normal DACAA.

A 61-year-old male fell from a position 1 m high when building a house. An iron rod, which protruded upward from a solid base in cement, penetrated this patient's neck 15 cm to the head and was successfully extracted by himself. On admission, he complained of headache and vomiting. General examination disclosed nasal bleeding, intraoral bleeding, and L figured skin laceration in the left side of his neck at the level of the thyroid cartilage. Mild disorientation (JCS2) was noted. Otolaryngological examination disclosed hyperemia on the left side of the vocal cord as well as at the dome of the superior pharynx. Plain skull film disclosed pneumocephalus and that a piece of bone fragment of the planum sphenoidale had penetrated the brain. CT demonstrated air in the subarachnoid space, ventricular hemorrhage, intracerebral hematoma in the right frontal lobe, and subarachnoid hemorrhage in the anterior interhemispheric fissure. CAG detected neither cerebral vascular abnormalities nor cerebral aneurysm. While staying in our department, he developed mild fever and CSF rhinorrhea. The diagnosis of bacterial meningitis was made from the CSF finding and was well controlled with conservative therapy. CSF rhinorrhea stopped spontaneously with conservative treatment. Sagittal MRI continuously demonstrated contusional hematoma in the base of the right frontal lobe just above the fractured planum sphenoidale and genu of the corpus callosum following the course of the intracranially invading iron rod. The right CAG on Day 10 demonstrated vasospasm on the A1 and a 1 cm sized saccular cerebral aneurysm at the proximal right fronto-polar artery. CAG on Day 17 again showed the persistent presence of the aneurysm. For the purpose of preventing delayed rupture of the aneurysm, radical surgical treatment was planned. Microsurgical dissection disclosed that the aneurysm was located just behind the elevated fracture of the planum sphenoidale. Severe arachnoid adhesion was noted around the aneurysm. The aneurysm was successfully clipped with preservation of the parent artery without inducing new neurological deficits. From the general, otolaryngological, neuroradiological, and operative findings, this aneurysm was diagnosed as a traumatic cerebral artery aneurysm following the penetration of the skull base by the iron rod. The CAG performed at 8 months postoperatively demonstrated the patency of the parent artery and that there was no recurrence of the aneurysm. An unusual case of a traumatic cerebral artery aneurysm following the penetration of the skull base by an iron rod was thus reported.

A 64-year-old male suddenly developed headache and nausea. He had been pointed 3 years before out as having an unruptured basilar artery aneurysm and a right middle cerebral artery aneurysm. Computed tomography (CT) revealed diffuse subarachnoid hemorrhage in the basal cistern and bilateral Sylvian and interhemispheric fissures. Hematomas in the anterior horns of the lateral ventricles and third ventricle were also seen. Angiography revealed an anterior communicating artery aneurysm, which, retrospectively, had been recognized as a small dilatation of artery wall 3 years before. An operation was performed and the anterior communicating artery aneurysm was successfully clipped. The intraoperative findings revealed the aneurysm was the ruptured one. The risk of rupture and surgical indication for unruptured small aneurysms are discussed.

A patient with multiple mycotic aneurysms associated with infective endocarditis is reported. A 45-year-old man was admitted on February 16, 2001 under the diagnosis of infective endocarditis. After alpha-streptococcus was identified by a blood culture, he was treated with high doses of antibiotics. However, 2 weeks after admission, he suddenly suffered from headache and mild left hemiparesis. A CT showed a parenchymal hematoma in the right parietal lobe. Cerebral angiography demonstrated aneurysms of the bilateral middle cerebral artery and the left posterior cerebral artery. At first, we trapped and resected the ruptured right middle cerebral aneurysm. After the surgery, we tried to treat two unruptured aneurysms by endovascular treatment. During the provocation test for the posterior cerebral artery, the arterial wall was perforated by a guide wire. The parent artery was occluded by coils at this site. Although the aneurysm was still filled by retrograde blood flow, it finally disappeared six months after treatment. The left middle cerebral artery aneurysm could not be treated because the provocation test showed cognitive deficits. The patient recovered from infective endocarditis after four-months of antibiotic therapy; and the unruptured aneurysm had not changed in size for 11 months. Recently, the outcome of patients with intracranial mycotic aneurysm is improved by development of multimodality management. Especially, endovascular therapy may become an effective treatment for unruptured aneurysms, but it is necessary to take risks, such as arterial perforation into consideration.

Abuse of the drugs like amphetamine, cocaine and "Ecstasy" may be complicated by intracerebral, subdural or subarachnoid haemorrhage. Contrary to historical opinion, drug-related intracranial haemorrhage (ICH) is frequently related to an underlying vascular malformation. We report the case of an 18-year-old man with a history of Ecstasy abuse preceding the onset of severe occipital headache. Cerebral computed tomography revealed right-sided subarachnoid haemorrhage and cerebral angiography showed right-sided middle cerebral artery aneurysm of 1 cm diameter. The patient was treated surgically with aneurysm clipping. Three weeks after onset of intracranial haemorrhage, neurological examination demonstrated normal findings. A history of severe headache immediately after using amphetamine, Ecstasy, or cocaine should alert doctors to the possibility of intracerebral haemorrhage. Arteriography should be part of the evaluation of most young patients with stroke or non-traumatic ICH.

A rare case of partially thrombosed giant serpentine right middle cerebral artery aneurysm presented. A 26 year old man initially presented with headache and 3 months later developed neurological deficit. Various stages of clot with patent residual lumen seen on neuroimaging, led to the diagnosis. Catheter angiography is the investigation of choice for evaluating the location, flow dynamics and extent of the serpentine aneurysm. The patient had embolisation done for the giant serpentine aneurysm.
