(3) They included enlargement of the lateral cisterns, loss of superior cerebellar vermian substance with prominence of the superior cerebellar cisterns, and fourth ventricle enlargements.
(4) Ultrasound was inadequate in initial assessment, as it missed or underestimated posterior fossa haemorrhage, particularly where this was extraparenchymal or vermian.
(5) The CT scans of six subjects (20%) differed considerably from the others as they displayed wide cortical or vermian sulci at the borderline of normal variations.
(6) Solitary tumors are located in the cerebellar hemipheres in about 80 per cent of cases, where they are of macrocystic type (type 2) in a proportion of two third; vermian tumors are equally of cystic and solid (type 3 and 4) types.
(7) From March 1976 to October 1977, 197 cases of brain tumors were examined by CT, 6 tumors (1 pineal tumor, 2 cerebellar vermian tumors and 3 supratentorial tumors) of which were radiated after the initial CT scan and re-examined by CT at every 400-1,000 rads radiation, and their grade of radiosensitivity could be evaluated.
(8) Cerebellar vermian tumors suspected of medulloblastoma were also diminished in size on CT after the 600 rads radiation.
(9) Findings of CNS lesions in both the midbrain (high-signal-intensity lesions) and the cerebellum (vermian atrophy) necessitate further characterization of these defects in terms of their progressive nature and clinical significance for patients with Usher's syndrome.
(10) Computed tomographic (CT) scans, however, usually can demonstrate the circle of Willis, and the basilar, sylvian quadrigeminal, and vermian cisterns.
(11) We reported a case of a 64-year-old man who presented a subarachnoid hemorrhage due to rupture of an aneurysm arising from the cortical branch of the superior cerebellar artery (SCA) at the junction of the superior vermian branch and the hemispheric branch.
(12) Areas of cerebellar vermian lobules, the fourth ventricle, the pituitary gland, and the corpus callosum were measured on sagittal images.
(13) In this case of paraneoplastic cerebellar degeneration, MRI showed cerebellar vermian atrophy when the brain CT scan was negative.
(14) Seventeen years later, at age 60, he had resection of a fourth ventricular vermian lesion, which was found to be histologically identical to the original lesion.
(15) Schizophrenia and affective psychoses share the following: 1) several treatments are effective in both, 2) similar modes of inheritance, 3) congruent seasonal birth excesses, 4) enlarged cerebral ventricles and cerebellar vermian atrophy, 5) dexamethasone non-suppression.
(16) Groups IIB and IIA only differed in drug use, and IIB had a higher incidence of brain damage except for anterior horn index and wide cerebellar sulci indicating vermian atrophy.
(17) The major changes that may occur in elderly individuals without neurologic deficits include enlargement of the ventricles, cortical sulci, and vermian subarachnoid spaces; multifocal areas of hyperintensity in the white matter and basal ganglia; a progressive prominence of hypointensity on T2-weighted images of the putamen, almost equal to that of the globus pallidus; an increase in the oxygen extraction ratio with normal or mildly decreased neuron metabolism; arteriosclerosis in large and small arteries and amyloid angiopathy in leptomeningeal cortical vessels; and decreased dopamine receptor binding in the corpus striatum.
(18) The central nervous system lesions were most prominent in the lateral pyramidal tracts of the spinal cord, the fasciculi gracili of the dorsal column in the cervical spinal cord and the cerebellar vermian white matter.
(19) LCCA was suggested the preclinical vermian atrophy by the statistical regression study.
(20) All five melanotic neuroectodermal tumors were resected and the vermian tumor was also irradiated.
Wormy
Definition:
(superl.) Containing a worm; abounding with worms.
(superl.) Like or pertaining to a worm; earthy; groveling.
Example Sentences:
(1) The most conspicuous and prevalent helminth was C. complanatum as fish were "wormy" and unmarketable due to the presence of high numbers of metacercariae.
(2) The impact of targetted treatment depends critically on the factors that generate heterogeneity in parasite burdens and on whether or not selectivity is based on a single or repeated identification of the 'wormy' fraction of the community.
(3) The findings over a 12-month follow-up period after one treatment included: mean monthly incidence of 20%, higher and more rapid return to previous prevalence and intensity of infection in children or 'wormy' persons than in adults or 'non-wormy' persons.
(4) Wormy individuals with heavy infections are shown to be predisposed to this state such that they reacquire heavier than average worm burdens following treatment.
