Background and Importance: Arachnoid cysts are benign nontumoral lesions that are usually found incidentally in brain imaging. Suprasellar Arachnoid Cysts (SSACs) are rare. They can cause hydrocephalus and increased intracranial pressure, lower cranial nerve impairment and endocrine disorder. Sometimes arachnoid cysts become complicated by subdural hematoma/hygroma.  Case Presentation: We...

Surgical Treatment of Suprasellar Arachnoid Cyst Dr. A. Barth, Neurochirurgische Klinik, Inselspital, CH-3010 Bern (Switzerland) Dear Sir, Suprasellar arachnoid cysts often present with hydrocephalus [1, 2]. Even if hydrocephalus can usually be treated without permanent shunting devices, the best surgical approach remains presently controversial concerning the operative risks and the avoidance ...

A 15-year-old female presented with primary amenorrhea and delayed onset of secondary sexual characteristics. Earlier she was operated for endoscopic third ventriculostomy (ETV) for a tense suprasellar arachnoid cyst with obstructive hydrocephalus. MRI revealed recurrence of hydrocephalus. Hormonal levels were suggestive of hypogonadism and deficiency of growth hormone. She was operated for fen...

Spinal epidural arachnoid cyst (EAC) is a rare, usually asymptomatic condition of unknown origin, which typically involves the lower thoracic spine. We report a case of posttraumatic symptomatic EAC with lumbar disc herniation. A 22-year-old man experienced back pain and sciatica after a traffic accident. Neurological examination revealed a right L5 radiculopathy. Magnetic resonance imaging dem...

MR imaging of the cervical spine is valuable for assessing traumatic injuries to the spinal cord and bony ligamentous structures. MR is also useful for detecting such long-term complications of spinal cord injury as syrinx, arachnoid cyst, cord adhesion, and persistent mechanical impingement on the spinal cord or spinal nerve roots. Treatment of cervical spine injuries that are mechanically uns...

Arachnoid cyst of the brain is common in children but its association with spontaneous subdural hygroma is rare. A case of a nine-year-old boy, without any preceding history of trauma, is presented here who came to the emergency department of a tertiary care hospital with complaints of headache, nausea, and vomiting for the last two weeks but more for the last two days. Examination showed a you...

We report a case of a middle aged patient with middle fossa arachnoid cyst that was complicated by subdural hematoma. This was demonstrated by magnetic resonance imaging that remain the most useful diagnostic tool, and providing excellent tissue specificity. Patient was treated by irrigating the hematoma through burrholes. Magnetic resonance imaging in the postoperative period showed a reductio...

A 68-year-old woman presented with a rare huge right occipital cystic lesion manifesting as progressive left hemiplegia. Cranial computed tomography revealed a 4 x 7 cm right occipital lobe thin-walled cyst with midline shift and compression of the ipsilateral ventricle. The patient underwent a single burr hole operation for cystography and delineation of the cyst anatomy, then a separate right...
