It is very rare that a foramen magnum arachnoid cyst induces compression of the spinal cord and syringomyelia, and currently there are few treatment experiences available. Here we reported the case of a 43-year-old male patient who admitted to the hospital due to weakness and numbness of all 4 limbs, with difficulty in urination and bowel movement. MRI revealed a foramen magnum arachnoid cyst w...

background: arachnoid cysts are cerebrospinal fluid (csf) fluid-filled sacs that are located between the brain and spinal cord. spinal column arachnoid cysts are rare and mostly asymptomatic, being mostly located in intradural regions. we reported a patient who presented with neurological deficits and mid-thoracic extradural arachnoid cyst treated with en-bloc resection. case presentation: pati...

The purpose of the present communication is to describe two patients, one with a congenital extradural and one with a congenital intradural arachnoid cyst of the spine and to review the relevant literature. Congenital spinal arachnoid cyst is a very rare cause of spinal cord compression. It is one of the most favourable spinal lesions for surgical removal and recovery of neurological function. ...

Extradural arachnoid cyst in the spine is an uncommon cause of spinal cord compression in the paediatric population. Most reported cysts have communication with the intrathecal subarachnoid space through a small defect in the dura. The reported child had spinal cord compression caused by a large spinal extradural arachnoid cyst in dorsal spine that did not communicate with the intradural subara...

Syringomyelia is a not infrequent pathology that develops related to changes in cerebrospinal fluid dynamics due to many etiological factors. The development of syringomyelia through a spinal arachnoid cyst is quite rare and has been defined in only 31 cases in the literature. A case due to thoracic epidural lipomatosis has also been reported. There have been no previous reports of thoracic reg...

BACKGROUND Idiopathic spinal arachnoid cysts are rare cystic masses of the spinal canal generally classified as intra- or extradural, based on anatomical presentation. However, this system may not effectively indicate treatment. OBJECTIVE To investigate the incidence, resection modality, and prognosis of spinal arachnoid cyst in a 15-year case series. PATIENTS AND METHODS A retrospective st...

Several types of intraspinal cyst develop within the spinal canal from the craniovertebral junction to the sacrum. These lesions occur in both children and adults. Arachnoid cysts are one of them and are more frequent in the paediatric population, being a relatively uncommon lesion in adults. The arachnoid cyst may be located intradurally or extradurally. The intradural type may be congenital o...

Spinal canal extradural arachnoid cyst is an uncommon, expanding lesion which may communicate with the subarachnoid space. They may be either intra or extradural with intradural cysts being less common. Spinal arachnoid cysts are usually in the thoracic spine, and they may cause symptoms due to spinal cord compression. Although surgery is the preferred way of management, there are reported case...

Spinal extradural arachnoid cysts usually cause symptoms related to spinal cord or nerve root compression. Here, we report an atypical presentation of a spinal extradural arachnoid cyst combined with congenital hemivertebra which was presented as a retroperitoneal mass that exerted mass effects to the abdominal organs. On image studies, the communication between the cystic pedicle and the spina...

Spinal arachnoid cyst presents a di agnosti c challenge to c linical neurologists as well as radiologists. Although not an infrequent cause of progress ive spasti c paraparesi s in the young and middle-aged , it is often overlooked in the differential diagnosis of progressive myelopathy. This is of concern in that early diagnosis and resection of these ben ign lesions could prevent progressive ...
