A 45-year-old woman had pyrexia, headaches, collapse and hyponatraemia. Intracerebral abscess, bacterial meningitis and subarachnoid haemorrhage were excluded. She was given intravenous antibiotics and gradually recovered. One month later she was readmitted with diplopia, headache and vomiting. Serum sodium was low (107 mmol/l) and a diagnosis of inappropriate ADH secretion was made. MRI scan showed a suprasellar tumour arising from the posterior pituitary gland. A skin rash gradually faded. Serum cortisol, prolactin, gonadotrophins and thyroid hormone levels were low. A pituitary tumour was removed trans-sphenoidally, she had external pituitary radiotherapy, and replacement hydrocortisone and thyroxine. She was well for 12 months when she developed progressive weakness and numbness of both legs. Examination suggested spinal cord compression at the level of T2 where MRI scanning showed an intradural enhancing mass. This spinal tumour was removed and her neurological symptoms disappeared. Nine months after this she developed facial pain and nasal obstruction. CT scan showed tumour growth into the sphenoid sinus and nasal cavities. A right Cauldwell-Luc operation was done and residual tumour in the nasal passages was treated by fractionated external radiotherapy and Prednisolone. Histological examination of the specimens from pituitary, spinal mass, and nasal sinuses showed Rosai-Dorfman disease, a rare entity characterized by histiocytic proliferation, emperipolesis (lymphophagocytosis) and lymphadenopathy. Aged 48 she developed cranial diabetes insipidus. Although Rosai-Dorfman syndrome is rare, it is being reported with increasing frequency, and should be borne in mind as a possible cause of a pituitary tumour.

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.

Subarachnoid hemorrhage secondary to ruptured intracranial arteriovenous malformation (AVM) during pregnancy, although rare, is a grave complication. We experienced 3 patients with AVM for cesarean section. Case 1: A 24-year-old woman suffered sudden vomiting and headache during the 22nd week of her first pregnancy. She was diagnosed as having the intracranial hemorrhage due to AVM. Because the patient was bleeding again at 29th week of pregnancy, emergency operation was performed. Her neurological symptom improved. Cesarean section was performed under general anesthesia at 34th week of pregnancy. Case 2: A 42-year-old woman of her first pregnancy had past history of subarachnoid hemorrhage due to AVM at the ages of 23, 28, 29 and 36. The malformation was not corrected surgically. Her neurological status was normal. Cesarean section was performed under spinal anesthesia. Case 3: A 29-year-old woman suffered sudden hemiplegia, vomiting and headache during the 40th week of her first pregnancy. She was diagnosed as having intracranial hemorrhage. Cesarean section immediately followed by the removal of an intra cranial hematoma under general anesthesia. Better perinatal outcome is expected when AVM rerupture is prevented by first performing cesarean section.

We described a case of cerebellar hemorrhage after trapping of a vertebral artery dissecting aneurysm. A forty-eight-year-old man had suffered from severe headache, vomiting and disturbance of consciousness. He was transferred to our hospital in an ambulance. Emergency CT scan showed subarachnoid hemorrhage in the posterior fossa predominantly, intraventricular hemorrhage and hydrocephalus change. Chest X-ray showed radiological evidence of pulmonary edema. The initial blood-gas determinations demonstrated a marked reduction in PaO2 and increased PaCO2. Five days after admission, the patient's condition was improving. Cerebral angiography was performed using the Seldinger method. It revealed a right vertebral artery dissecting aneurysm just distal to the posterior inferior cerebellar artery. We performed an operation to trap the VA dissecting aneurysm. Blood pressure was well controlled under 140 mmHg during the operation and he recovered from anesthesia completely. On the day after the operation, suddenly the patient's consciousness began to deteriorate. Emergency CT scan was performed and it showed SAH, cerebellar hemorrhage and diffuse swelling of the cerebellum on the same side as the operation. We suspected rebleeding of the aneurysm due to a clip's having slipped. Reoperation was performed, but the clip was not displaced and there were no definite bleeding vessels on the operative field. Consequently only external decompression and resection of the right cerebellum were performed. We discuss pathogenesis of the occurrence of hemorrhage in this particular case after trapping. We also review the relevant literature.

Cerebral arteriovenous malformations (AVMs) are considered to be congenital disorders. However, their familial occurrence has so far been described in only 19 families in the literature. The authors report on two cases in one family and review the literature. A 45-year-old female subject with sudden onset of headache and vomiting due to a subarachnoid haemorrhage from a small AVM in the posterior part of the corpus callosum near the midline on the left side was studied. Irradiation of the AVM using Leksell's gamma knife led to its complete obliteration. Her older sister presented with temporal seizures at the age of 49 and later also with left hemiparesis, left hemihypaesthesia and dizziness - caused by a large AVM in the right temporal lobe. This AVM was treated by a combination of embolization and irradiation by the Leksell's gamma knife.

A 29-year-old male with Down's syndrome presented with severe headache and vomiting. Computed tomography demonstrated subarachnoid hemorrhage. Left carotid angiography showed severe stenosis of the middle cerebral artery 2 cm distal to its origin, as well as abnormal hyper-vascularization near the stenosis site similar to that seen in moyamoya disease. Right carotid angiography showed no abnormalities. However, slight stenosis of the distal part of the bilateral vertebral arteries was noted. There was no aneurysm. We judged that the subarachnoid hemorrhage had been caused by rupture of the moyamoya-like vessel. Some patients with Down's syndrome have anatomical vascular abnormality and vascular fragility. The cerebral vascular abnormality found in this case may be part of the systemic vascular abnormalities associated with Down's syndrome. The vascular changes in some adult patients with Down's syndrome may be a sign of premature aging, and long-term studies with periodic vascular examination of patients with Down's syndrome need to be performed.

A 57-year-old female was admitted to our hospital because of headache, nausea, and vomiting. Head CT scan demonstrated subarachnoid hemorrhage. Cerebral angiography showed the absence of the right internal carotid artery, and skull base CT of the bone window level revealed the absence of the right carotid canal. The right middle cerebral artery (MCA) and anterior cerebral artery (ACA) were opacified from the left internal carotid artery. The right A1 portion was hypoplastic and the distal portion of the right M1 portion was replaced by several minute complicated anastomotic vessels connected to the right M2 portion. The right MCA territory was mainly supplied by collateral flow from the right ACA and the right posterior cerebral artery via the leptomeningeal anastomosis. These was neither aneurysm nor arteriovenous malformation. The second angiography, 1 week after the initial angiography, showed the same hemodynamic pattern and aneurysms were not found. We diagnosed the patient as agenesis of the right internal carotid artery and the etiology of subarachnoid hemorrhage was suspected to be a rupture of the anastomotic vessels between the right M1 and M2. She was discharged on the 21st hospital day without any neurological deficit.

A 58-year-old male presented with a rare association of an infratentorial arteriovenous malformation (AVM) and ipsilateral persistent primitive trigeminal artery (PPTA) manifesting as sudden onset of headache and vomiting. Computed tomography revealed subarachnoid hemorrhage, and digital subtraction angiography demonstrated an infratentorial AVM mainly fed by the left superior cerebellar artery via the left PPTA. The patient refused radical treatment for the AVM, and was conservatively treated. The adjacent AVM may have been important in the preservation of the PPTA, as blood flow into the infratentorial AVM via the PPTA and the hemodynamic stress to the PPTA could have disturbed the spontaneous closure of the PPTA.

We report a case of a true posterior communicating artery aneurysm. A 51-year-old male suffered a subarachnoid hemorrhage with severe headache and vomiting. A true posterior communicating artery aneurysm was recognized after repeated angiography on the seventh day. Right frontotemporal craniotomy was performed and the aneurysm was successfully clipped. The incidence of true posterior communicating artery aneurysms ranges from 0.1-2.8%, and 21 cases including our case have been reported in detail. There are no reported cases in which the aneurysm arises from the branching site of perforating arteries. In almost all cases the dome of the aneurysm projects inferiorly or posteriorly or laterally, so perforating arteries from the posterior communicating artery rarely interfere with dissection of the aneurysm or neck clipping. In a few cases, true posterior communicating artery aneurysms had been diagnosed as IC-PC aneurysms preoperatively, leading to intraoperative aneurysmal rupture or postoperative neurological deficit or death. In the cases of a fusiform aneurysm or an aneurysm of wide-based neck, there may be no other choice than trapping of the aneurysm. It is difficult to predict whether trapping causes postoperative ischemic complications.

A 28-year-old woman suffered severe back pain and headache during exercising on three occasions during the prior two-month period. On admission, the physical examination revealed symptoms of meningeal irritation, nuchal rigidity, severe headache, continuous nausea, and vomiting. Cerebral computed tomography of the intracranial subarachnoidal space revealed no subarachnoid hemorrhage. Her cerebrospinal fluid was bloody. Spinal magnetic resonance imaging identified a posterior mediastinal tumor adherent to the left side of the 5th thoracic vertebra and an abnormally expanded blood vessel near the mediastinal tumor. In addition, a high signal intensity lesion appeared to be present on the surface of the spinal cord. A mediastinal neoplasm was removed through standard thoracotomy. During surgery, marked enlargement was noted in some veins (hemiazygos and 5th intercostal veins) which apparently had been constricted by the mediastinal tumor. Surgical and radiological findings suggested a relationship between the constricted venous return due to the tumor and the patient's spinal subarachnoid hemorrhage.
