the remarkable evolution of surgical management of cerebral hydatidosis towards an earlier diagnosis and proper treatment is evident from this 22-year retrospective study of our experience with 19 cases seen at shiraz university medical institutions. both cases of iatrogenically-induced infected cysts were seen during the pre-ct era. the optimistic view of being able to remove all the cysts int...

The incidence of choroid plexus cysts represents approximately 1% of fetal anomalies. We describe a case in which fetal ultrasonography and fetal magnetic resonance scans were used to identify a large choroid cyst in a fetus without the use of a diagnostic amniocentesis to detect aneuploidy. After birth, the child underwent surgery. In conclusion, the nature of prenatal intracranial cysts shoul...

We present two cases of surgically proved colloid cysts that were more apparent on CT scans than on MR images. These cysts, while hyperdense on CT scans, were nearly isointense with brain on multiple MR sequences. This relative lack of visibility represents a potential pitfall when imaging a patient with headache.

A 14-year-old boy presented with 3 months of generalized headache that had increased in intensity and frequency with associated light-headedness. Primary arachnoid cysts result from developmental abnormalities; more rare secondary cysts develop as a result of head injury, meningitis, tumors, or as a complication of brain surgery.

A 33-year-old woman presented with occasional mild nonlateralized headache. Examination was normal. Brain MRI revealed a neuroglial cyst in the right hemisphere which expanded slowly but relentlessly over subsequent years (figure 1; figure e-1 on the Neurology Web site at www.neurology.org). At the last MRI, the lesion produced considerable mass effect, but the patient’s examination was still n...

Radio frequency lesioning of nuclei in the thalamus or the basal ganglia can be used in order to reduce symptoms caused by e.g. movement disorders such as Parkinson’s disease. Enlarged cavities containing cerebrospinal fluid (CSF) are commonly present in the basal ganglia and tend to increase in size and number with age. Since the cavities have different electrical and thermal properties compar...

OBJECTIVES There are supportive evidences about the possible role of latent Toxoplasma. gondii infections on the behavior and neurologic functions, such as increased dopamine levels in the brain. The aim of this study was to examine anti-toxoplasma activity of aripiprazole that is an atypical anti-psychotic drug in mice. MATERIALS AND METHODS Mice were randomly divided into four groups, inclu...

BACKGROUND AND PURPOSE Although pineoblastoma is the main brain abnormality associated with hereditary retinoblastoma, recent studies suggest an association with pineal cysts. This association is important because some pineoblastomas mimic pineal cysts. If there is a relationship, then radiologists should be aware of it because diagnostic confusion is possible. Mental retardation and congenital...

megalencephalic leukoencephalopathy with subcortical cysts (mlc) is an autosomal recessive disorder characterized by macrocephaly and a slowly progressive clinical course marked by ataxia, spasticity and mental decline. mlc is caused by mutations in the gene mlc1 which encodes a novel protein, mlc1. here we report 4 cases presenting with macrocephaly, spasticity, ataxia and abnormal cerebral wh...
