A 68-year-old man with arterial hypertension and diabetes mellitus suffered a stroke with hemiparesis. The ischemic infarction was demonstrated by computer assisted tomography and angiography. At the site of the original infarction a large brain abscess developed several months later and caused the patient's death. A secondary hematogenous infection of the necrotic area (in this case Staphylococcus aureus, probably from bronchiectasis) seems likely. Other cited case reports show that after cerebral necrosis of various origin the possibility of a secondary brain abscess should be considered.

The case of a 26 year old woman who had been taking tranexamic acid to prevent uterine bleeding due to an IUD and who died from thrombosis of the left internal carotid artery is reported. The patient's father had died at age 54 of myocardial infarction. Otherwise the family history was entirely negative for thromboembolic disease. The patient was a mild smoker. She had been previously healthy and in particular, she was not affected with hypertension, diabetes, or dyslipidemia. She had carried to term 2 uncomplicated pregnancies. 40 days prior to hospital admission her gynecologist had inserted an IUD. The insertion of the IUD was followed by persistent uterine bleeding, and for this reason she began treatment with tranexamic acid (1.5 g/daily). Uterine bleeding persisted despite this treatment, and the IUD was removed. Because of persistence of a mild uterine bleeding, tranexamic acid was continued. 2 hours before admission the patient suddenly presented a left sided hemiparesis with disarthria and vomiting. On admission she was stuporous. The left side of her face drooped and the strength of the left arm and leg was markedly decreased. Both arm and leg reflexes were symmetrical. Her blood pressure was 110/70. An electroencephalogram on arrival confirmed a right sided cerebral lesion. Subsequently the patient's condition deteriorated rapidly. She developed a full left hemiplegia and became deeply comatose. A CAT scan performed 4 hours after admission showed no abnormalities. A CAT scan performed 3 days after admission showed a large cerebral infarction involving nearly the whole right cerebral hemisphere. The patient's condition remained essentially unchanged until she died 6 days after admission. Permission for autopsy was refused. Antifibrinolytic drugs competitively inhibit plasminogen activators and noncompetitively plasmin. Thromboembolic complications after the administration of antifibrinolytic drugs have long been recognized. The use of IUDs is often associated with troublesome uterine bleeding and particularly excessive menstrual bleeding. To avoid these complaints, antifibrinolytic drugs are increasingly used.

Multiple Sclerosis (MS) cases found at autopsy in patients who had died from other diseases and in whom no sign or symptom could be related to MS are called "asymptomatic". Three cases are reported. The first patient was a 62 year old man who presented with a slowly progressive disturbance of gait, incontinence and deterioration of intellectual function. A falx meningioma was surgically removed. The patient died 3 years later with an acute respiratory illness. Examination of the brain disclosed evidence of the operation and numerous old plaques disseminated through the cerebral hemispheres (centrum semi-ovale, periventricular regions, internal thalamus and junction between cortex and white matter) and in the brain stem. The second case, a 77 year old woman with diabetes mellitus and hypertension, presented with cortical blindness and disturbances of memory of acute onset. She died one year later. Examination of the brain showed multiple infarcts involving the territories of both posterior cerebral arteries and the left middle cerebral artery. Numerous old plaques were seen in the periventricular regions, in the corpus callosum and in the left middle cerebellar peduncle. The third case, a 60 year old woman with mitral and aortic stenosis, presented with cortical deafness and transient right hemiparesis. She died 5 years later. Brain examination showed infarcts involving both middle cerebral artery territories. There was also many old plaques in the periventricular areas, thalamus, internal capsule, centrum semi-ovale, brain stem and right nucleus dentatus. In the 3 cases, the optic tracts were normal. The spinal cord, examined only in the first case, was also normal. The asymptomatic character of these MS cases can be explained first by the location of the plaques and the lack of spinal cord and optic tract involvement. It could also be due to the small size of the plaques and to axonal preservation. Such features are rare since our 3 observations have been selected from a pathological collection of 125 MS cases and 9,300 general neuropathological records. Six other cases have been previously reported by other authors.

The authors have performed 631 urgent suprapubic transvesical adenomectomies in patients with prostate adenoma complicated by acute urine retention or hemorrhage. Prearranged and urgent interventions had, by the authors' experience, virtually the same rate of postoperative complications and lethal outcomes. The risk in urgent adenomectomy performed in 294 patients was attributed to their concurrent affections: postinfarction cardiosclerosis, myocardial ischemia or hypertensive crisis, hemiparesis after brain apoplexy, bronchial asthma, diabetes mellitus, hepatic cirrhosis, chronic lymphoid leukemia, drug polyallergy, multiple tumors of the urinary bladder, stomach, etc., in stage T1-3NOMO. 80 patients had intermittent chronic renal failure. In compensation of severe concurrent diseases and satisfactory condition of the patients urgent adenomectomy was conducted within 24 hours since hospitalization. Longer interval (within 24-72 hours) was necessary in subcompensation of the concurrent diseases, intermittent chronic renal failure which were intensively treated. The authors achieved uneventful postoperative course for 272 (92.5%) high-risk patients. Postoperative lethality made up 3.06%. According to 1-11-year follow-up 7 patients died, for the most part of blood and respiratory diseases. Functional long-term outcomes were good in 83.5% of the patients. Basing on their experience, the authors specify indications to urgent adenomectomy and optimal time of its conduction. Contraindications to urgent adenomectomy were revised and narrowed.

We reported a rare case of marked dilatation of the bilateral common carotid artery (CCA) associated with stenosis of the left middle cerebral artery (MCA). A 64-year-old female was admitted with right hemiparesis and dysarthria. She was hospitalized 2 years ago for cholecystitis. For 5 years, she has been under medical treatment for hypertension, diabetes mellitus, hyperlipidemia, cardiac failure associated with hypertrophic cardiomyopathy, and atrial fibrillation. Brain CT scan showed infarction of the left corona radiata. Angiography revealed marked dilatation of the bilateral CCA and the internal carotid artery (ICA), moderate dilatation of the innominate artery and the right subclavian artery, kinking of the right CCA, diverticular outpouching of the left ICA, and stenosis of the right external carotid artery and the left MCA. Breast CT scan revealed moderate dilatation and marked calcification of the ascending aorta and the aortic arch. Laboratory examination did not show any sign of inflammation, rheumatoid factor (RA), antistreptolysis-O (ASLO) and antinucleotic antibody. Based on the clinical course, radiological findings and laboratory data, possible diagnosis of the dilatation of the bilateral CCA was discussed with particular emphasis on arteriosclerotic aneurysm and aortitis syndrome.

Eleven cases of rhinocerebral mucormycosis (RM) encountered over a 13-year period were reviewed. Predisposing factors included leukemia (36%), diabetes mellitus (27%), aplastic anemia (9%), myelodysplastic syndrome (9%), and treatment with immunosuppressive medications necessary to maintain solid organ or bone marrow graft viability (64%). Two patients had no predisposing factors. Clinical findings included headache (73%), fever (55%), black nasal eschar (45%), orbitofacial cellulitis (36%), cranial nerve palsy (36%), altered sensorium (36%), and hemiparesis (27%). Seven patients presented with destruction of the paranasal sinuses and local invasion; three with direct extension to the frontal or temporal lobes. Four patients displayed hematogenous dissemination to the cerebrum, brain stem, and cerebellum from a primary pulmonary focus. The seven patients with sinus involvement were treated with aggressive surgical debridement. Two patients with focal intracerebral lesions underwent either open craniotomy or stereotactic biopsy. Amphotericin B was administered intravenously to all patients. Local irrigation via a percutaneous catheter was performed in the seven patients with sinus disease and in one case of intracranial abscess. All seven patients with intracranial infection died, in contrast to four patients that survived with infection localized to the sinuses and orbits. All survivors had been treated with a combination of surgery and amphotericin B therapy. This review demonstrates that RM is increasingly affecting patients with sources of immunosuppression other than diabetes mellitus. Early aggressive therapy to prevent cerebral involvement by this severe infection provides the best chance for a good outcome.

Left pure motor hemiparesis occurred in a 42-year-old woman with a history of hypertension and diabetes mellitus. The left hemiparesis affected the arm and leg equally. The face was almost spared, with only a very slight facial asymmetry. Brain CT and MRI showed a small infarction located in the external 2/3 of the right cerebral peduncle. Cerebral angiography did not reveal significant abnormalities.

The authors report a rare case of intracranial aspergillosis presenting marked granulomatous pachymeningitis. A 58-year-old male who had a three-year history of diabetes and chronic bronchitis was referred to us because of progressive left hemiparesis and dysarthria. Postcontrast CT scan showed a ring-enhancing lesion with marked perifocal edema in the right parietal lobe, and right subdural enhancing mass. MR image revealed hypertrophic dura mater in the right convexity. On June 9, 1992, partial removal of the intra-axial cystic mass and granulomatous dura mater was performed. A number of characteristic aspergillus hyphae were recognized in the resected cyst and granulomatous dura mater. Postoperatively, the patient was treated with amphotericin-B and fluconazole. But granulomatous pachymeningitis became progressively enlarged and eventually created a large mass effect again. On January 23, 1993, the patient died of pneumonia. Cerebral aspergillosis is getting common but preoperative diagnosis is still difficult because of its causing several clinical features such as brain abscess, granuloma, intracerebral hemorrhage, cerebral infarction, meningitis, and encephalitis. Several comments were made about the pathogenesis of these features, and the necessity of early diagnosis and treatment was emphasized.

A 61-year-old woman was admitted to the hospital on September 18, 1991 because of left hemiparesis, dysphagia, and dysarthria since five days before. She was formerly pointed out diabetes mellitus and hypertension, but she did not receive any treatment. The MRI showed a high signal area in the right paramedian portion of the upper pons on T2 weighted image and proton image. The angiography showed that persistent primitive proatlantal artery originated from the left internal carotid artery and joined to the horizontal portion of the left vertebral artery. The image of carotid-vertebrobasilar system and proatlantal artery showed so severely arteriosclerotic. This is the first report of brainstem infarction with persistent primitive proatlantal artery. In this case, the pontine infarction was thought to occur on the basis of the arteriosclerosis of blood vessels and change of blood flow of carotid-vertebrobasilar system due to persistent primitive proatlantal artery.

The association of movement disorders with hypoglycemia has been rarely noted in the past. We recently observed 2 patients with documented hypoglycemia and paroxysmal dyskinesias. One patient had evidence of an insulin-secreting tumor. The other patient had insulin-dependent diabetes, and also experienced recurrent episodes of hypoglycemic hemiparesis. Classical adrenergic symptoms of hypoglycemia were absent in both patients. Our observations support the concept that the development of neuroglycopenic symptoms cannot be predicted from blood glucose measurements alone, but must depend on other factors controlling the availability or metabolism of glucose in the brain.
