Intracranial arachnoid cysts are congenital lesions that are frequently detected incidentally. About 30% of patients have a symptomatic epileptic seizure as the presenting symptom, occasionally with other focal neurologic signs. A case is presented of a young male patient with medically refractory temporal lobe epilepsy. Following his neurological examination, epileptic zone was defined in the ...

Sir, The association of a speckled lentiginous naevus, an organoid naevus with sebaceous differentiation and skeletal and neurological anomalies, constitutes a specific syndrome that has been called phacomatosis pigmentokeratotica (1). It has been hypothesized that the co-occurrence of the two different naevi reflects a so-called twin spot phenomenon (1 – 3). We herein describe an additional ca...

Arachnoid cysts are primarily developmental in origin and constitute rare, benign lesions. Sylvian arachnoid may infrequently present with subdural and/or intracystic hemorrhage. Hemorrhage is typically of venous occurs due to stretching tearing bridging veins, depending on minor traumas. The annual risk bleeding associated cysts, no additional complaints other than headache an asymptomatic cou...

Quadrigeminal arachnoid cyst are one of the rarest form intracranial cyst, this unique congenital malformation posses an special risk for hydrocephalus and neurological symptoms due to its proximity aqueduct brain stem. The treatment tends be surgical in cases when hypertension presents by hydrocephalus. Few non quadrigeminal with clinical follow up has been studied global literature . Here it’...

arachnoid cysts are congenital lesions arising from the arachnoid membrane. the incidence of arachnoid cysts in the general population is around 0.1% and their most common location is the middle fossa. arachnoid cysts usually present during the childhood and are identified incidentally. when symptomatic, the most common presentations include headache and seizure. the popular treatment for this ...

Spinal extradural arachnoid cysts (SEACs) are relatively rare cause of compressive myelopathy. SEACs can be either congenital or acquired, but the etiology and the mechanism for their development are still unclear. A number of cases have been reported in the literature, and the one-way valve mechanism is the most widely accepted theory which explains the expansion of cysts and spinal cord compr...

Spinal extradural arachnoid cyst (SEDAC) is a cyst in the spinal canal that protrudes into the epidural space from a defect in the dura mater. Most cases are sporadic; however, three familial SEDAC cases have been reported, suggesting genetic etiological factors. All familial cases are associated with lymphedema-distichiasis syndrome (LDS), whose causal gene is FOXC2. However, FOXC2 mutation an...

Intracranial arachnoid cyst (IHAC) is considered as rare congenital lesions. Usually the arachnoid cyst remains asymptomatic and incidentally picked -up on routine cranial imaging. Mostly, the intracranial arachnoid cyst is located in the sylvan fi ssure, cerebello-pontine angle, or suprasellar region. However, arachnoid cyst located in the interhemispheric fi ssure is regarded as extremely unc...
