Arachnoid Diverticula .
Intracranial or spinal cavities containing a cerebrospinal-like fluid, the wall of which is composed of arachnoidal cells. They are most often developmental or related to trauma. Intracranial arachnoid cysts usually occur adjacent to arachnoidal cistern and may present with HYDROCEPHALUS; HEADACHE; SEIZURES; and focal neurologic signs. (From Joynt, Clinical Neurology, 1994, Ch44, pp105-115) .
Diverticulum .
Diverticula .
Diverticulosis .
A pouch or sac developed from a tubular or saccular organ, such as the GASTROINTESTINAL TRACT. .
Arachnoid .
Arachnoid Mater .
Arachnoid Maters .
Arachnoids .
Mater, Arachnoid .
Maters, Arachnoid .
A delicate membrane enveloping the brain and spinal cord. It lies between the PIA MATER and the DURA MATER. It is separated from the pia mater by the subarachnoid cavity which is filled with CEREBROSPINAL FLUID. .
Arachnoiditis .
Arachnoid Membrane Inflammation .
Inflammation, Arachnoid Membrane .
Arachnoid Membrane Inflammations .
Arachnoiditides .
Inflammations, Arachnoid Membrane .
Acute or chronic inflammation of the arachnoid membrane of the meninges most often involving the spinal cord or base of the brain. This term generally refers to a persistent inflammatory process characterized by thickening of the ARACHNOID membrane and dural adhesions. Associated conditions include prior surgery, infections, trauma, SUBARACHNOID HEMORRHAGE, and chemical irritation. Clinical features vary with the site of inflammation, but include cranial neuropathies, radiculopathies, and myelopathies. (From Joynt, Clinical Neurology, 1997, Ch48, p25) .
Diverticulitis .
Diverticulitides .
Inflammation of a DIVERTICULUM or diverticula. .
