A 27-year-old male presented with a rare association of a ruptured orbitofrontal artery aneurysm and a dural arteriovenous malformation (DAVM) fed by both ethmoidal arteries, manifestation as severe headache, nausea, and vomiting. Computed tomography revealed a hematoma within the right frontal lobe and diffuse subarachnoid hemorrhage. The aneurysm was clipped successfully and the hematoma was evacuated. After an uneventful postoperative course, the patient was referred for gamma knife radiosurgery to treat the DAVM. In this case, the DAVM was asymptomatic and pathogenetically unrelated to the aneurysm, which demanded urgent treatment.

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.

The clinical and radiographic findings of 68 children and adolescents with nontraumatic intraparenchymal brain hemorrhage were analyzed retrospectively. There were 43 boys and 25 girls, and the average age was 7.1 years (range, 3 months to 18 years). The most common presenting symptom was a combination of headache or vomiting (40 cases, or 58.8%). Hemiparesis was the major presenting sign in 11 (16.2%) of the children, seizures occurred in 25 (36.8%) patients, and 6 (8.8%) children were irritable. Only 2 (2.9%) children were comatose at presentation. One or more risk factors for hemorrhage were found in 61 (89.7%) of 68 children. A third (23 cases, or 33.8%) had an arteriovenous malformation or fistula; altogether 29 (42.6%) children had some type of congenital vascular anomaly. Hematologic or coagulation disorders were present in 22 (32.4%) patients, and 9 (13.2%) patients had brain tumors. Hemorrhage could not be attributed to systemic hypertension in any child. The likelihood of establishing the cause of bleeding was greater when evaluation included cerebral angiography (97.3% versus 80.4% without angiography). Half (34 cases, or 50.0%) of the patients regained normal neurologic function. Six (8.8%) patients died, either directly or partly as a consequence of the hemorrhage. The remaining patients had various neurologic sequelae, including 17 (25.0%) with hemiparesis, 5 (7.4%) with aphasia, 7 (10.3%) with epileptic seizures, and 3 (4.4%) with hydrocephalus. More detailed follow-up studies are needed to obtain more information about the frequency of cognitive sequelae.

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.

An 11-year-old male was admitted because of frequent vomiting and truncal ataxia which had lasted for over one week. He had clear consciousness but slowly-progressive mild headache and ataxic gait. Cranial CT revealed a 4 cm hematoma in the right cerebellar hemisphere. Angiography showed a 2 x 2 cm nidus of a pial arteriovenous malformation (AVM) in the right hemisphere fed from the right posterior inferior cerebellar artery and draining into the inferior hemispheric vein. We performed a surgical resection of the AVM after decompression therapy to counteract the brain edema. He recovered completely without any neurological deficits. This case suggests that cerebellar hemorrhage caused by AVM should be considered as a possible diagnosis when mild symptoms of headache and ataxia proceed gradually.

Surgical emergencies can be missed easily in children, who are not always able to volunteer relevant information. Awareness of the entities discussed in this review might help the EP uncover subtle clues to early diagnoses that might not be initially apparent. Ill-appearing children who have abdominal pain and vomiting should be considered to have ischemic or necrotic bowel until proven otherwise. Possible diagnoses include volvulus, intussusception, and necrotizing enterocolitis. Bilious vomiting, especially in a young infant, should be considered to be an indication of a high bowel obstruction such as midgut volvulus, which warrants immediate surgical consultation. Significant rectal bleeding with abdominal pain can result from intussusception, volvulus, or an inflamed Meckel's diverticulum. Rectal bleeding with unstable vital signs can result from an upper GI bleed (eg, peptic ulcer disease). Painless rectal bleeding can result from a Meckel's diverticulum, polyps, arteriovenous malformation, or a tumor. Examination of the genitalia is imperative, especially in boys, to exclude the possibility of an incarcerated hernia or testicular torsion.

A case with arteriovenous malformation (AVM) associated with moyamoya phenomenon is reported. The 44 year-old female patient was presented with headache and vomiting. Computed tomography (CT) scan showed intraventricular hemorrhage. Cerebral angiography showed right frontal AVM and severe stenosis of right internal carotid artery. The AVM was fed by typical moyamoya vessels, Heubner's artery, and external carotid artery (ECA). We tried to embolize a bleeding point, compartment attached to lateral ventricle, but we could not. So, we embolized feeders from ECA and sent the patient to radiosurgery. We discuss here treatment and etiology of such rare condition.

A 52-year-old man suddenly experienced headache and vomiting. Computed tomography demonstrated a small area of hemorrhage in the right cerebellar hemisphere. Angiography revealed a thalamic arteriovenous malformation (AVM) fed by the bilateral medial posterior choroidal arteries and left marginal tentorial artery, and drained into the confluence via the cerebellar veins without flow into the supratentorial venous system. The draining veins included two varices, one of which, in the right cerebellar hemisphere, was thought to be the source of bleeding. The AVM nidus was removed via the right occipital transtentorial approach. A portion of a drainer adhered to the surface of the great vein of Galen but without opening into the galenic system and all drainers from this thalamic AVM flowed into the infratentorial cerebellar venous system.

Primary intraventricular hemorrhage is very rare in adults and is even more infrequent in children. We present a 15-year-old girl who presented to the hospital because of sudden severe headache, vomiting and fever. Neurological examination only showed neck stiffness. A brain computed tomography showed blood in the ventricular system. Conventional angiography revealed an arteriovenous malformation originating in the right pericallosal artery branches. Gamma-knife radiosurgery was performed without relevant complications. A follow-up cerebral angiography showed disappearance of the arteriovenous malformation. When a primary intraventricular hemorrhage is detected in a young patient it is mandatory to rule out an underlying lesion such an arteriovenous malformation. Treatment options include surgery, interventional radiology and radiosurgery, alone or in combination.
