The clinical manifestations of intracranial arachnoid cyst lesions similar. Some patients may have paresis or seizures. There are also local symptoms, such as exophthalmos and head is not known.
Arachnoid cysts are divided into congenital and secondary two classes. The former is born, the latter due to trauma, inflammation caused by subarachnoid extensive adhesion results. A congenital arachnoid cyst is a bag shaped structure in which the cerebrospinal fluid is enclosed in the arachnoid membrane. Not associated with subarachnoid space. Secondary to arachnoid adhesion, a cyst in the subarachnoid space, containing cerebrospinal fluid. Good hair at small cranial fossa, also found in the cisterna magna, four fold around the brain pool and suprasellar pool, etc..
Arachnoid cysts are benign cyst of a brain. Arachnoid cyst wall and CSF like fluid. Cysts are located on the surface of the brain, but not in the brain. Mostly single, a small number of hair, often located in the brain and brain fissure. Large volume can be compressed at the same time the brain and skull, can produce neurological symptoms and changes in the skull. The disease is more common in children, more men, more on the left than the right side. According to the cause of the disease, it can be divided into three types: congenital, traumatic, and arachnoid cysts.
Diagnosis of congenital arachnoid cyst: history of meningitis and intracranial hypertension. CT scan can be confirmed. But sometimes it is difficult to differentiate from congenital arachnoid cyst. Multiple cysts are not suitable for surgery, but can be removed to produce the main clinical symptoms of cysts. Cerebrospinal fluid shunt surgery with hydrocephalus and intracranial hypertension.
After the injury of arachnoid cyst and leptomeningeal cyst. The mechanism for the damage caused by fracture of skull defect, with dural tear, below the subarachnoid hemorrhage or subarachnoid space around the edge of adhesion caused by local disturbance of cerebrospinal fluid circulation induced local arachnoid process to the dura fissure and fracture line, in the brain could not beat off under the impact of gradually formed cysts, the fracture edge continues expansion, called growth fracture. Cysts can occur in the scalp, but also under the oppression of the cerebral cortex. Sac filled with clear liquid with scar tissue around. Such as the injury of brain tissue can damage the pia mater, herniation of the fracture, and have the same lateral ventricle enlargement, and even the formation of porencephaly.
The disease is more common in infants and young children. Common is the parietal scalp injury of linear fracture, no rupture, local swelling under the scalp, after 2 to 3 years after the fracture line crack expansion. Bone margin outward tilt as lips shaped, brain cyst oppression can produce seizures, hemiparesis and other neurological symptoms.
X-ray radiography of the skull showed local soft tissue bulge, the edge of the bone defect area was irregular, wavy, and the inner plate was more obvious than the outer plate. CT scan can clear the scope of the cyst, showing a low density shadow, sometimes the same as the expansion of the ventricles or the brain through the malformation.
The treatment of this disease is to remove the cyst, repair the dura mater defect and repair the skull defect.
