We studied the natural history of patients with a diagnosis of benign coital headache who presented to a private neurological clinic between the years 1978 and 1991. Thirty-two patients (24M, 8F) were invited to participate and 26 patients (83%) responded. The period of follow-up ranged from six months to 14 years (median 6 years). Thirteen patients (50%) had recurrent attacks of coital headache epochs separated by intervals of up to 10 years. Eleven of these patients suffered a concomitant primary headache whereas this was present in only one of those patients without recurrent attacks of coital headache (p < 0.001). In all but one patient, who had a transient blurred vision, the headache was not accompanied by nausea, vomiting, visual disturbances, sensory/motor disturbances, or unconsciousness. We concluded that benign coital headache can be clearly distinguished from headaches due to cerebral aneurysm or arteriovenous malformation rupture. The presence of a concomitant primary headache syndrome is a risk-factor for recurrence of coital headache.

A 64-year-old, hypertensive female suddenly experienced severe headache. On admission, the patient had almost clear consciousness but was slightly restless and complained of severe headache and nausea. Neurological examination revealed only neck stiffness. A computed tomographic scan revealed subarachnoid hemorrhage. Angiographically, bilateral internal carotid and vertebral arteries had the "string of beads sign" at their cervical portion, and the left internal carotid artery also had the same sign at its cavernous portion. The left vertebral artery had low-origin posterior inferior cerebellar artery and a berry-shaped aneurysm at its distal trunk. A diagnosis of cervical and intracranial fibromuscular dysplasia (FMD) with a ruptured berry-shaped aneurysm of the distal vertebral trunk was made. The berry-shaped aneurysm was successfully treated with proximal clipping. Angiographically, right renal and axillary arteries also had the "string of beads sign," and the patient's hypertension seemed to be renovascular in etiology. The co-existence of intracranial FMD and cerebral aneurysm of unusual location suggests a possible relationship between the FMD and the development of cerebral aneurysm.

A case of a basilar bifurcation aneurysm associated with common carotid artery occlusion is reported. A 40-year-old woman was admitted to our hospital with severe headache and nausea. On admission, no neurological abnormality was observed. CT scan showed thin subarachnoid hemorrhage in the basal cistern. Left vertebral angiograms revealed a basilar bifurcation aneurysm located in the high position. Also, the left internal and external carotid arteries were supplied through the anastomotic muscle branches of the left occipital and vertebral artery. The trunk of the left common carotid artery was not visualised from its origin on the aortogram. CT scan at the level of C6 showed thinning of the left common carotid artery and contrast enhancement study indicated occlusion. Neck clipping of the aneurysm was successfully performed by right trans-sylvian approach. Right zygomatic arch was removed to obtain a wider operative field for avoiding further retraction of the brain tissue. The postoperative course was uneventful except transient disorientation for two weeks. It has been well known that internal carotid artery occlusion may be associated with cerebral aneurysm in some cases. However, it seemed to be a rather rare case that the common carotid artery occlusion due to arteriosclerosis was associated with cerebral aneurysm. Hemodynamic factor was positively suggested for aneurysmal formation in this case.

A case of recurrent cerebral aneurysm after complete neck clipping is described. A 47-year-old male who presented with headache and nausea underwent neck clipping of a berry aneurysm of the left middle cerebral artery. Ten days later, angiographic findings suggested the presence of a second, large aneurysm adjacent to the first, which suggested misplaced clipping. Reoperation confirmed that a new aneurysm had formed next to the original aneurysm. A possible explanation of the recurrence is as follows. The M1 flowed into the M2 at a right angle. The aneurysmal neck was situated on the distal end of the M1 and the dome protruded antero-inferiorly at an angle of nearly 90 degrees to the long axis of the M1 opposite the origin of the M2. The parent artery bulged slightly, and its wall was thin and reddish, just distal to the aneurysmal neck. Proximal to the neck there was another small bulge, but the wall here was normal. These bulges were coated with Oxycel and Biobond at the time of aneurysmal neck clipping. After clipping, blood flow into the dome was interrupted, and the consequent hemodynamic stress caused the bulges to expand dramatically and form a new aneurysm. The authors conclude that there is a likelihood of early recurrence after neck clipping if the parent artery exhibits such morphological features as observed in this case.

A case of intracranial traumatic aneurysms occurring after surgical treatment of a large cerebral aneurysm is reported. A 56-year-old man was admitted to our department with complaints of headache, nuchal pain and nausea. Left carotid angiography (Lt-CAG) revealed a large aneurysm, measuring 20 mm in maximum diameter, of the azygos anterior cerebral artery. Successful clipping operation was performed on day 17 of subarachnoid hemorrhage. Unfortunately, small cortical branches were pulled out during the procedure from the right pericallosal artery. The postoperative Lt-CAG showed formation of two other aneurysms. Second operation was done on day 28 after the first operation. These aneurysms were located at the previously injured sites on the right pericallosal artery. From the history sited above, we diagnosed them as traumatic aneurysms. The second operation resulted in successful obliteration of these two traumatic aneurysms. Literature review yielded 25 similar cases, and the authors discuss the etiologic factors of the traumatic aneurysm due to surgical procedure.

We present a case of a sixteen year old boy with coarctation of the aorta who suffered ruptured cerebral aneurysm. Both cerebral and aortic lesions were successfully corrected. He complained of sudden headache and nausea. Subarachnoid hemorrhage was diagnosed by computed tomography of the head. Cerebroangiography demonstrated coarctation of the aorta. Clipping of cerebral aneurysm was done at first, then three months later, complete resection of the aortic coarctation and artificial graft replacement was done by using femoral veno-arterial cardiopulmonary bypass.

In order to study the frequency and characteristics of post-angiography headache, we interviewed 45 consecutive patients (mean age +/- SD = 57 +/- 15 years; M/F = 15/30) who underwent transfemoral cerebral angiography for: ischemic cerebrovascular disease (n = 33); suspected arteriovenous malformations (n = 4; one confirmed); suspected cerebral aneurysm (n = 5; two confirmed); and arterial dissection (n = 3; one confirmed and one was a follow-up study of a previously demonstrated dissection). Postangiography headache developed in 15 (33%) patients, 125 +/- 99 min after the completion of the study. It was unilateral in nine (60%) patients, homolateral to the usual side of migraine headache in two or three migraineurs, and pulsating in six (40%). Nausea, vomiting, photophobia, and phonophobia accompanied postangiography headache in 20%, 7%, 33%, and 20% respectively. Postangiography headache fulfilled the International Headache Society criteria for migraine without aura (except for the number of attacks) in 27% of patients. Patients with and those without postangiography headache were comparable in mean age, sex, and indication for angiography. Fifty-three percent (8/15) of patients with postangiography headache and 23% (7/30) of the non postangiography headache group reported prior recurrent headaches (P = 0.047, likelihood ratio chi-square). Postangiography headache has the characteristics of delayed arterial pain which may be related to a catheter-induced or contrast dye-induced release of vasoactive substances, notably nitric oxide and serotonin.

A case is presented of a de novo aneurysm of the distal posterior inferior cerebellar artery with intraventricular hemorrhage. A 67-year-old woman was admitted to our hospital with sudden onset of severe headache and loss of consciousness. Computed tomography (CT) scans showed subarachnoid hemorrhage. Angiography demonstrated three aneurysms: an aneurysm of the right vertebral-posterior inferior cerebellar artery, an aneurysm of the bifurcation of the basilar artery, and an aneurysm of the left middle cerebral artery. Considering the distribution of the hemorrhage on CT scans, we concluded that the cause of the hemorrhage was rupture of the vertebral-posterior inferior cerebellar aneurysm. The vertebral-posterior inferior cerebellar aneurysm and the middle cerebral aneurysm were successfully clipped, postoperative angiograms showing the complete clippings. At that time, however, there were no abnormal findings in the left posterior inferior cerebellar artery. Six years later, she was readmitted to our hospital because of sudden onset of headache, nausea, and vertigo. CT scans showed an intraventricular hemorrhage, especially in the fourth ventricle, although subarachnoid hemorrhage was not clearly found. Angiography revealed an aneurysm of the left distal posterior inferior cerebellar artery. She underwent clipping of the aneurysm verified by postoperative angiograms. However she had bacterial meningitis and died from pneumonia and disseminated intravascular coagulopathy. De novo aneurysms of the anterior circulation have often been reported. Carotid, ligation, smoking, the use of oral contraceptives, congenital anomalies and hypertension are major risk factors in the formation of aneurysms. A de novo aneurysm of the distal posterior inferior cerebellar artery is, however, extremely rare. In this case, the right posterior inferior cerebellar artery disappeared when the de novo aneurysm was found. So it is supposed that hemodynamic changes caused by the clipping of the right vertebral-posterior inferior cerebellar aneurysm and the left middle cerebral aneurysm had contributed to the formation of the de novo aneurysm of the left distal posterior inferior cerebellar artery. In the present study, we review the literature on the aneurysm at the distal posterior inferior cerebellar artery and on the de novo aneurysm of the vertebrobasilar artery, and discuss the radiological findings and features.

Hemodynamic stress is considered one of the most important factors in the growth of cerebral aneurysms. The authors report a rare case of cerebral aneurysm located at the distal posterior cerebral artery (PCA) in which collateral circulation developed due to occlusion of the internal carotid artery (ICA). A 73-year-old male was admitted to our hospital with a sudden headache and nausea. Computerized tomography (CT) revealed an intracerebral hematoma in the right parieto-occipital lobe and the acute subdural hematoma in both the cerebral interhemispheric fissure and the convexity. Moreover, angiography revealed a saccular aneurysm at the P4 portion of the PCA. The right ICA was occluded at the cervical portion and collateral circulation which had developed in the PCA was extended to the region of the right middle cerebral artery. The aneurysm was clipped 15 days after admission without new neurological complications. This case demonstrates that increased hemodynamic stress plays a role in the growth and rupture of cerebral aneurysm.

Cerebral hyperperfusion syndrome is a rare but well-described complication following carotid endarterectomy or stenting. Clinical signs are ipsilateral, throbbing, unilateral headache with nausea or vomiting, seizures, and neurological deficits, with or without intracerebral abnormalities on CT scan, such as brain edema or intracerebral hemorrhage. Subarachnoidal hemorrhage is rarely described especially if it occurs isolated. We describe a 74-year-old man with a history of high blood pressure, hypercholesterolemia, atrioventricular block with pacemaker, and ischemic cardiopathy with coronary bypass. He underwent right carotid endarterectomy for a 90% NASCET asymptomatic stenosis. Four days after surgery, he complained of unusual headaches with right, throbbing hemicrania. Nine days after surgery, he presented with left hemiplegia and a partial motor seizure. He had fluctuant altered consciousness, left hemiplegia, and left visual and sensory neglect. Brain CT showed right frontal subarachnoidal hemorrhage without parenchymal bleeding. Cerebral angiography found no cerebral aneurysm, no vascular malformation, but a vasospasm of the left middle cerebral artery. Transcranial Doppler confirmed this vasospasm. Evolution was favorable with no recurrence of seizures but with an improvement of the neurological deficits and vasospasm. Physicians should bear in mind this very rare complication of endarterectomy and immediately perform neuroimaging in case of unusual headache following endarterectomy or angioplasty.
