Baylor Neurology Case Of The Month Department of Neurology. Diagnosis 1. Spontaneous intracranial hypotension 2. Secondary ArnoldChiari Malformation Patient 28 is http://www.bcm.tmc.edu/neurol/challeng/pat28/summary.html
Extractions: 2. Secondary Arnold-Chiari Malformation The most worrisome and confusing aspects of this case, however, were the findings of CSF pleocytosis and diffuse meningeal enhancement on MRI ( see initial MRI ). In fact, the patient was referred to our service for a possible meningeal biopsy because of the unexplained nature of her problem and these MRI findings. The numerous possibilities of diffuse meningeal enhancement include inflammatory, infectious, and neoplastic processes. Meningeal enhancement is seen with meningeal carcinomatosis and lymphoma but the appearance is usually one of nodular enhancement, which may be focal or diffuse. Our patient had no evidence of blood cell dyscrasia on peripheral smear. Additionally this patient had no other symptoms or laboratory findings to suggest the presence of a malignancy. Neurosarcoidosis can give a similar appearance but it is usually associated with cranial neuropathy (53%), parenchymal disease (48%), aseptic meningitis (22%), peripheral neuropathy (17%), myopathy (15%) and/or hydrocephalus (7%). There is usually some evidence of systemic disease (97%) and elevation of serum angiotensin enzyme (ACE) levels. None of these were present in our patient. Lyme disease was considered. There is a triad of meningitis, radiculitis and neuritis without fever that is highly suggestive of this disease. Meningeal enhancement may or may not be seen, but is more often at nerve roots. Initially, patients have mild meningeal signs including headaches, myalgias, stiff neck and cranial nerve involvement. After several weeks patients may have cardiac conduction abnormalities, meningial signs, multiple cranial neuropathies, peripheral mononeuropathies and encephalopathy, as well as transitory erythematous blotchy rashes. The third stage typically involves development of a chronic arthritis. Our patient had none of these findings and her Lyme titers were negative.
Extractions: The dural findings seen with intracranial hypotension are due to congestive changes caused by chronically low intracranial pressure. The pressure differential may be maintained by an occult CSF leak, and many patients can give a history of previous lumbar puncture or trauma. Uniform thickening of the dura is a characteristic feature, and the lack of nodularity or a basilar distribution can help distinguish this process from metastatic disease or TB/sarcoid. The cerebellar tonsils may occasionally sink through the foramen magnum, leading to an acquired Chiari I malformation. BACK TO UNKNOWNS BACK TO CATEGORIES HOME NEXT CASE

Other characters Spontaneous intracranial hypotension, (SIH) a syndrome with reduced CSF pressure that occurs in the absence of dural puncture, surgery or trauma. The pathogenesis is usually considered to be an occult CSF leak through small defects in the meninges with a resultant decrease in CSF volume and pressure. The characteristic headache in SIH is similar to postlumbar puncture postural headache in that it is aggravated by sitting or standing and relieved by lying down. Other associated symptoms, seen less commonly, include stiff neck, nausea and vomiting, diplopia and cranial neuropathies, producing vertigo, tinnitus, photophobia and changes in hearing. CSF may be normal or reveal increased protein, xanthochromia or lymphocytic pleocytosis. By definition, the CSF pressure in SIH is low (less than 60 mm H O) and may be unobtainable via lumbar puncture, the so-called dry tap. Treatment options for intractable headache in SIH are similar to those for postdural puncture headache and include bed rest, analgesics, sedatives, oral caffeine, intravenous hydration, epidural blood patch and epidural saline infusion. The usual clinical course of SIH in most patients is spontaneous resolution over a period of weeks to months. The diagnostic intracranial imaging findings include diffuse, intense pachymeningeal enhancement on post contrast T1-weighted sequences (
