A case of fungal aneurysm associated with presumed Tolosa-Hunt syndrome is reported. A 57-year-old man was admitted to our hospital with complaints of left blepharoptosis, headache and weight loss. Neurological examination revealed left ophthalmoplegia without facial hypesthesia. Visual acuity was normal. Laboratory studies showed raised ESR, 4+ glycosuria, and a blood sugar of 351mg/dl. Computerized tomography (CT) scan and left carotid angiography were considered normal. Left orbital venography showed no filling of the left cavernous sinus. Diabetic ophthalmoplegia was suspected by a neurologist. The patient was treated with insulin therapy, but visual acuity worsened, and hypesthesia was noted in the first and second divisions of the left trigeminal nerve. Subsequent CT scan demonstrated a high density lesion, which was homogeneously enhanced, in the left cavernous portion and the superior orbital fissure. The patient was presumed of Tolosa-Hunt syndrome, and prednine therapy (30mg/day) was started. On the second day after the administration of prednine, hypesthesia of the first and second division of the left trigeminal nerve improved. After 9 days of prednine therapy, the patient suddenly complained of severe headache, and lapsed into a coma. Massive hemorrhage with subarachnoid hemorrhage was recognized on the CT scan, with a marked midline shift to the right. The hematoma was immediately removed. A ruptured cerebral aneurysm was found at the bottom of the hematoma. The aneurysm was located in the distal portion of the left middle cerebral artery. Aneurysm clipping with external decompression and bilateral ventricular drainage was performed.(ABSTRACT TRUNCATED AT 250 WORDS)

Injury to the carotid or vertebral artery is an important clinical entity that requires angiography for definitive diagnosis and evaluation. The common carotid artery may be injured by penetrating trauma while the internal carotid artery is usually damaged by either trivial or blunt trauma. With trivial trauma extracranial internal carotid artery dissection should be considered if there is unilateral headache, Horner's syndrome or delayed transient ischaemic attack, and intracranial dissection if a profound neurological defect occurs immediately following trauma. Injury to the internal carotid artery following blunt trauma includes dissection of the extracranial internal carotid artery, carotid-cavernous fistula and pseudoaneurysm formation. These should be considered in a patient with delayed neurological deficit, mandibular or skull fracture, a constellation of orbital signs or diffuse subarachnoid haemorrhage, respectively. Vertebral artery injury is less frequent. Dissection typically follows abrupt cervical rotation and occurs at C1-2, whereas penetrating trauma may involve either the proximal or distal vertebral artery and occlusion, arteriovenous fistula or pseudoaneurysm may be found. Endovascular techniques may be used in either the carotid or vertebral artery to close fistulae or occlude an extensively damaged vessel.

A case is reported of ruptured dissecting aneurysm of the intracranial vertebral artery (VA) operated on with VA trapping and bilateral posterior inferior cerebellar artery (PICA) side-to-side anastomosis. A 42-year-old male suddenly developed severe headache and vomiting. On admission, 3 hours later, he was in a state of moderate confusion (Japan Coma Scale 3) and had neck stiffness. Computed tomography (CT) revealed diffuse subarachnoid hemorrhage, especially thick in the posterior fossa with right side dominance. Right vertebral angiography disclosed a fusiform dilatation with proximal narrowing of the right VA which originated just proximal to the VA-PICA junction. Lateral suboccipital craniectomy was undertaken with the patient in a left park bench position. Right VA was dilated and discolored black, and right PICA arose from the proximal portion of this aneurysmal dilatation. Since it was impossible to clip the VA distal to the PICA for the proximal clip-occlusion, the VA including the VA-PICA junction was trapped. Considering the risk of developing infarction at the PICA territory, bilateral PICA was anastomosed at their posterior medullary segment in a side-to-side fashion because the occipital artery (OA) had been cut at the skin incision and could not be used for the OA-PICA anastomosis. The postoperative course was benign, but a mild lateral medullary syndrome developed. CT revealed no abnormal low density area and left vertebral angiography demonstrated the patency of the bypass. Thereafter, the deficit subsided gradually and the patient was discharged. He is presently working without neurological deficit.(ABSTRACT TRUNCATED AT 250 WORDS)

A 45-year-old woman with prosthetic valves replacement, was admitted with severe headache and vomiting one month after starting danazol treatment at 300 mg per day. She was receiving long-term anticoagulation with warfarin and dipyridamole, taking 3.5 mg and 300 mg per day respectively. The patient's thrombotest value was less than 6% at the time of admission. Cranial CT revealed subarachnoid hemorrhage. Warfarin and danazol treatment ware discontinued with replenishment of vitamin K. Recovery was uneventful. Danazol is 2, 3 isoxazol derivative of 17-alpha-ethinyl testosterone. As such, it shares the property of C 17 alkylated steroids in potentiating the action of coumarin. It is suggested that danazol affects the turnover of vitamin-K-dependent clotting factors, an impairment of synthesis being a likely mechanism. The possible hazard of the potentiating effect of danazol on warfarin should be widely appreciated.

A rare case of dissecting aneurysm of distal posterior inferior cerebellar artery (PICA) is reported. A 51-year-old woman was admitted to our hospital complaining of severe headache and nausea. CT scan revealed subarachnoid hemorrhage which was thicker in the posterior fossa. The vertebral angiography demonstrated an aneurysm on the telovelotonsillar segment (Lister's classification) of the left PICA. On the third day, the left suboccipital craniotomy was performed and the fusiform aneurysm was resected. The postoperative course was uneventful. Histological examination of the resected aneurysm showed a dissection between the ruptured elastic lamina and the tunica media. Dissecting aneurysm of distal PICA is still belong to a rare entity. In all three cases found in the literature, the dissecting aneurysms are sited in the anterior medullary segment of PICA. Probably, this is the first report described a dissecting aneurysm on the more distal part-telovelotonsillar segment of PICA. The clinical features, pathogenesis and treatment of intracranial dissecting aneurysms are briefly discussed with reviewing the literature.

We report three cases of ruptured cerebral aneurysms associated with systemic lupus erythematosus (SLE). A 52-year-old woman (case 1) with a fifteen-year history of systemic lupus erythematosus suddenly lost consciousness. She was admitted in a state of deep coma. A computed tomography (CT) scan revealed acute hydrocephalus and diffuse subarachnoid hemorrhage in the basal, interhemispheric and bilateral Sylvian cisterns. Fifteen years prior to this admission, cerebral angiograms demonstrated no cerebral aneurysm. She underwent ventricular drainage immediately. Postoperatively, her condition did not improve, and she died on the 18th day. During the autopsy, two saccular cerebral aneurysms were found: one aneurysm was at the right middle cerebral artery bifurcation, and another one was on the anterior communicating artery, which had disruption of the internal elastic lamina and medial smooth muscle, and infiltration of inflammatory cells. In the major cerebral arteries, for example the bilateral internal carotid arteries, disruption or dissection of the internal elastic lamina, intimal fibrosis and transmural infiltration of inflammatory cells were observed. The second patient, a 36-year-old woman with a six-year history of SLE, was admitted to our hospital with sudden severe headache. A CT scan showed subarachnoid hemorrhage, and cerebral angiograms disclosed saccular cerebral aneurysms on the anterior communicating artery and the left superior cerebellar artery, and a fusiform one on the left posterior cerebral artery. Surgery was not recommended because of her multiple medical problems. Her consciousness improved gradually over 2 months. She was transferred to the department of internal medicine for treatment of renal failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Involuntary movement complicated with the postoperative stage of the ruptured cerebral aneurysm is extremely rare. And, the pathophysiology of the involuntary movement has not been established yet. The authors report such a case because of its rarity and to make the mechanism of its appearance clear. The case was a 45-year-old female who was transported to our clinic after the onset of sudden headache. On admission, she had no neurological deficits without severe headache. CT scan revealed subarachnoid hemorrhage, and left carotid angiogram showed an aneurysm at the bifurcation of the left internal carotid artery. On the day of admission, neck clipping for the aneurysm was successfully performed. Postoperative course was uneventful without mild right hemiparesis which diminished until two weeks after operation. Since the 24th day from operation, athetoid involuntary movement occurred to her four toes. 123I-IMP SPECT revealed low perfusion from left frontal base to caudate, and CT scan showed atrophy of the left caudate. Athetoid involuntary movement as postoperative complication of ruptured cerebral aneurysm has not been reported without our case. We suppose it was caused by the ischemic effect of the left caudate due to the operative retraction or the delayed vasospasm after subarachnoid hemorrhage.

A case of traumatic carotid-cavernous fistula (CCF) which presented subarachnoid hemorrhage long after the injury is reported. A 24-year-old male was admitted to the National Yokohama Hospital with complaints of severe headache and nausea. CT scan and cerebral angiography showed subarachnoid hemorrhage due to ruptured CCF. His right visual acuity has disappeared after a traffic accident 5 years before, and he had hit his forehead again 3 years previously. He experienced severe headache twice for 2 weeks after his admission. He was transferred to Kanagawa Rehabilitation Center to be treated with intravascular surgery. Plain CT showed high density areas in the basal cisterns. CT after contrast infusion disclosed a small enlarged high density area in the right cavernous sinus, and showed an enhanced mass lesion in contact with the right ventrolateral side of the midpons. The right internal carotid angiogram showed high flow CCF, fed only by the internal carotid artery. It drained mainly into the basilar plexus, partially into the basal vein of Rosenthal and the inferior petrosal sinus. The CCF was found at the C4 portion of the right internal carotid artery. CT and the angiogram revealed a part of the CCF developing into a varix in the ventral side of the prepontine cistern. It ruptured and the patient developed subarachnoid hemorrhage 5 years after the head injury. The CCF was intravascularly embolized by a detachable balloon. Early treatment for CCF is necessary to prevent the occurrence of subarachnoid hemorrhage if a part of the CCF develops into a varix.

A case of ruptured aneurysm in the hypoplastic proximal anterior cerebral artery (A1 portion) is reported. This 25-years old man complained of the sudden onset of severe headache and vomiting on January 11, 1989. He was referred to our hospital on the same day, and CT scan revealed subarachnoid hemorrhage. Cerebral angiography on the next day revealed an aneurysm in the hypoplastic A1 portion of the right anterior cerebral artery, and no branch was present at the site of the aneurysmal neck. He was operated on using the right pterional approach. The A1 portion was trapped and the aneurysm was removed successfully. The histology of the aneurysm was that of the usual type of the saccular aneurysm. The post-operative course was uneventful. He was discharged with no neurological deficit two months after the operation. As far as we know, there has been no report on a ruptured aneurysm in the hypoplastic A1 portion. We also reviewed the 55 aneurysms in the A1 portion that have been reported in the literature.

The authors present a case of sphenoid ridge meningioma presenting as subarachnoid hemorrhage. A 56-year-old man came to our hospital with a complaint of severe headache developed during evacuation of the bowels. Computed tomogram on admission revealed a mass lesion of high density, which was homogeneously enhanced with contrast media, in the medial part of the left sphenoid ridge, but no evidence of the intracranial hemorrhage. Nevertheless, the cerebrospinal fluid obtained by lumbar puncture was bloody, indicating the occurrence of subarachnoid hemorrhage. Cerebral angiograms showed no abnormality except for the downward displacement of the suprachnoidal segment of the left internal carotid artery. During the operation, the adhesion between the tumor and the cortical vein was observed and the subarachnoid hemorrhage was recognized exclusively around the vein. These findings indicates that the present hemorrhage may be derived from the vein. In the previous reports of meningioma associated with intracranial hemorrhage, the origin of hemorrhage and the pathophysiological mechanism for hemorrhage have been speculated from both operative and histological findings. In consideration of these speculations, we discussed the possible mechanism for the breakdown of the cortical vein in the present case.
