✓ Thirty-four of 87 consecutive patients with subarachnoid hemorrhage from a cerebral aneurysm had a premonitory minor leak. There were 12 men and 22 women, aged 25 to 73 years (mean 44.4 years). Twenty-two had a small and 12 had a large aneurysm located on the internal carotid artery (17 cases), anterior communicating artery (10 cases), middle cerebral artery (five cases), and pericallosal artery (two cases). Fifty-two percent of patients with a minor leak from an internal carotid artery aneurysm had ipsilateral, hemicranial, hemifacial, or periorbital pain. Half of the patients initially saw a physician, but in no case was the correct diagnosis made. Twenty-five patients had a major rupture within 24 hours to 4 weeks after findings suggesting a minor leak, with a mortality rate of 53%. Nine other patients were diagnosed by lumbar puncture or computerized tomography (CT) scanning after initial misdiagnosis and were operated on, without mortality, before a major rupture could occur. The CT scans were negative in 55% of patients with a minor leak, but lumbar puncture, when performed, was always positive. A minor leak prior to major aneurysmal rupture is a common occurrence and, if unrecognized, is associated with a high mortality. Computerized tomography scanning is unreliable in diagnosing this event, and lumbar puncture is the examination of choice once intracranial hypertension has been ruled out.

✓ Aneurysms arising from the intracavernous portion of the internal carotid artery very rarely rupture. A patient is presented in whom rupture of an aneurysm wholly within the cavernous sinus caused a subarachnoid hemorrhage. The aneurysm was successfully clipped via a direct surgical approach. The possible mechanism by which subarachnoid hemorrhage occurred is briefly discussed.

✓ Six patients with intracranial mycotic aneurysms of extravascular origin are reported. Four had aneurysms of the intracavernous portion of the internal carotid artery associated with thrombophlebitis of the cavernous sinus, and two had aneurysms of the cerebral arteries associated with meningitis. An aneurysm of this type may rupture, producing subarachnoid hemorrhage, or it may become thrombosed and decrease in size or spontaneously disappear. In some patients it may persist and develop calcification in the wall.

✓ The author reports on 41 aneurysms of the proximal internal carotid artery (PICA) demonstrated in 36 patients with subarachnoid hemorrhage. The patients included a striking preponderance of women, and there was a high incidence of multiple aneurysms. In cases with multiple aneurysms the PICA aneurysm was usually found incidentally, a more distal aneurysm on the internal carotid artery being the source of hemorrhage. An infundibulum at the origin of a posterior communicating artery was unusually common in these patients. The origin of the ophthalmic artery is proposed as the angiographic landmark of the level at which the internal carotid artery penetrates the dura mater.

Object. The authors of this study evaluated the efficacy of simultaneous microscopic and endoscopic monitoring during surgery for internal carotid artery (ICA) aneurysms. Methods. The endoscopic technique was applied during microsurgery in 11 patients with 13 aneurysms. Nine of these lesions were located on the posterior communicating artery (PCoA), three in the paraclinoid region, and one on the anterior choroidal artery (AChA). Eight patients had unruptured aneurysms and three had ruptured aneurysms. The endoscope was introduced after first exposing the aneurysm through the microscope and was gripped firmly by an air-locked holding arm fitted with a steering system throughout the entire surgery, including dissection of the perforating arteries and application of the aneurysm clips. Regarding paraclinoid aneurysms, clips were applied through direct visualization of the ophthalmic artery and the proximal neck. In a case involving a superior hypophyseal artery aneurysm in the paraclinoid segment, a ring clip was applied without removing the bone structure around the optic canal. In all aneurysms of the PCoA and the AChA, perforating arteries behind the lesion were identified and dissected using endoscopic control. The aneurysm clip was applied in the best position in a single attempt in 10 of 11 patients. There was no surgical complication related to the endoscopic procedures. Conclusions. Simultaneous monitoring with the microscope and endoscope is extremely useful in applying clips to ICA aneurysms. This combined method allows for direct dissection of the aneurysm, perforating vessels, and the main trunk in an area not visible through the microscope's eyepiece and promises better surgical results.

✓ Aneurysms of the intracavernous portion of the internal carotid artery may become very large, but they very rarely rupture. A case is described in which rupture of such a lesion resulted in a lethal massive subdural hematoma with transtentorial herniation. This is the second reported case of substantiated intracranial rupture from a wholly intracavernous carotid artery aneurysm.

✓ The authors report a case of a basilar artery aneurysm approached by the transsylvian route; the aneurysm was successfully clipped through the space distal to the carotid bifurcation and between the frontal and temporal lobes. This approach is useful when the internal carotid artery is short, sclerotic, and difficult to mobilize. Special care should be taken when retracting perforating arteries and the posterior communicating artery.

Introduction : A 51‐year‐old lady with a past medical history of Essential Hypertension, Hypothyroidism, prior Herpes Zoster infection 8 weeks ago was admitted with complaints of abdominal pain, bilateral flank pain, and restlessness. Her initial workup was significant for hyponatremia and hypokalemia. On the 3rd day of admission, she developed acute hypoxemic respiratory failure which led to intubation. At that time, CTA Chest was not done but CT Chest revealed prominent mucous plugging with left side glass ground opacities, Ultrasound of lower extremities revealed right common femoral vein DVT which led to concerns that she may have suffered from Pulmonary Embolism and led to starting Heparin drip. On the 6th day of admission, she developed Acute Encephalopathy, MRI Brain revealed acute infarcts in bilateral cerebral cortices and cerebella, CT Angiogram Head showed acute subarachnoid hemorrhage in the high posterior right parietal lobe, stenosis of the right high cervical internal carotid artery, and irregular, the appearance of the arterial vasculature throughout and CT Angiogram Neck abrupt change in caliber of the right ICA, 1.5 cm distal to the bifurcation with markedly severe narrowing of the majority of the extracranial right ICA throughout its course. A cerebral Angiogram was done which showed diffuse tandem segments of tandem cervical and intracranial portions of the right internal carotid artery and she was given nitroglycerin was administered as a therapeutic intervention. Lumbar Puncture showed WBC 2, RBC 7, Protein 162, Glucose 64, VZV PCR was negative, CSF VZV IgG Antibody positive at 303 IV (>165 IV indicative of current or past infection). Serum VZV IgG Antibody was positive at >4000 IV. Infectious Diseases were consulted after Lumbar Puncture, they initially started Acyclovir but once the Serum VZV IgG Antibody came back much higher than Serum VZV IgG Antibody levels, their assessment was that VZV vasculitis is unlikely and Acyclovir was discontinued. Eventually, the case was discussed at Neuroradiology which led to us getting a repeat MRA Neck without contrast which showed a concentric T1 and T2 hyperintensity along with a small and irregular caliber right cervical ICA consistent with dissection. She eventually completed a 21‐day course of Nimodipine due to underlying Subarachnoid Hemorrhage. Methods : NA Results : NA Conclusions : Our case demonstrates how it can become difficult to ascertain the etiology of stroke in certain patients. Our patient presented with multiple non‐specific symptoms initially and it was later on due to her Acute Encephalopathy that her Strokes and Subarachnoid Hemorrhage were discovered. It is still difficult to pinpoint whether the cause of strokes was dissection or VZV infection. Lumbar Puncture remains an essential tool to complete work up on uncommon etiologies of stroke.
