In cases of encephalitis associated with an ovarian teratoma, histology often shows an intense WBC infiltrate in areas of the teratoma with neural tissue.6 Tissue in the teratoma expresses the NMDA receptor.7 In the syndrome of ovarian teratoma and encephalitis, elevated titers of anti-NMDAR antibodies are often present in serum and CSF. The original MRI (8 years earlier) that first revealed abnor- malities had been interpreted as normal. The differential diagnosis of the lesion in the left T7–T8 foramen included perineurial cysts and nerve-sheath tumors, specifically schwannomas and neurofibromas.

MRI performed with the administration of contrast material revealed no enhancement and revealed multiple lesions in- volving the thoracic and lower cervical nerve roots that were interpreted as perineurial cysts. Gene Therapy 7:867-74, 2000. Such cysts were first characterized in 1938 by the neurosur- geon Isadore M. Rheumatoid arthritis diet, exercise, home remedies, and alternative medicine What about rheumatoid arthritis and pregnancy? He recognized that the cysts form only on dorsal roots and that they can invaginate into the dorsal-root ganglia or nerve- root fascicles to damage neuronal cell bodies or axons. Later he reported that these cysts could cause sciatica, backache, or the cauda equina syn- drome, similar to intervertebral disk herniations, and he published numerous papers and a mono- graph describing effective surgical treatments for these cysts that came to bear his name.3 Tarlov cysts form only on the dorsal nerve roots because only the cell bodies of sensory neurons migrate out from the spinal cord during embryonic development, leaving behind a sleeve of dura and subarachnoid space. Tarlov cysts are most common at sacral levels, presumably reflect- ing the greater hydrostatic pressure there.

High intraluminal pressure can gradually expand them, and very large cysts can compress and damage motor (anterior) roots, the spinal cord, or sur- rounding bone or can cause leakage of cerebro- spinal fluid. Symptoms Associated with Tarlov Cysts Could this patient’s thoracic pain be due to the visualized Tarlov cysts? In large studies, the prev- alence of these cysts on lumbosacral MRI images ranges from 1.5 to 2.1%.4-7 Radicular neuropath- ic pain caused by damage to the nerve root that bears the cyst is the most common symptom,8,9 and the most common location of the pain is in the lumbosacral region.3,5,8,10 In a study involv- ing 122 patients with symptomatic Tarlov cysts (84% women; mean age, 54 years), in whom other potential causes had been ruled out by neurologic examination and diagnostic testing, all patients had local or radiating pain (sciatica) or both, and 10% had bladder or bowel incontinence.11 These symptoms, as well as the marked female predom- inance, are consistent with this patient’s presen- tation.5,11 This patient’s pain was primarily tho- racic, at the location of the cysts seen on early imaging studies; however, she also reported more typical symptoms of sacral pain, leg and foot pain and numbness, and incontinence. Prevalence of Symptoms Due to Tarlov Cysts How can we be sure the cysts are the cause of this patient’s symptoms? However, if microscopic teratomas could precipitate the syndrome, how is the physician to know which women without imaging evidence of a teratoma should have their ovaries surgically explored or removed? In addition, more than one degenerative change in a patient is often identified on spine imaging. In several studies, Tarlov cysts were thought to be the cause of symptoms in 20 to 30% of patients, because of the localization of the symptoms and the ab- sence of other abnormalities on imaging.3,5,6 An electrophysiological study involving a small num- ber of patients with sacral Tarlov cysts showed abnormal sural-nerve action potentials in 45% of the patients, always on the same side as the cysts, suggesting that electrophysiological testing might help identify cysts that are causing nerve dam- age.12 Imaging studies in this patient revealed no explanation for her radicular symptoms other than the cysts, so it is reasonable to conclude that they are the cause.

I have found that most physicians are either unaware of the existence of Tarlov cysts or be- lieve that they do not cause symptoms.

suggested an underlying connective-tissue disor- der. Co-investigator: Comparison of cervical spine expansile laminoplasty to cervical laminectomy in patients with cervical myelopathy or myeloradiculopathy due to multiple level cervical spinal stenosis. Medical treatment and follow-up I followed the patient for just over a year after her first consultation with me. Is there an arthritis diet? I advised her that definitive manage- ment of the chest pain would require procedural intervention, and she began to consider neuro- surgical evaluation for laminectomy. When I telephoned her home a month after our last visit (15 months after her initial evalua- tion at this hospital) to check on her progress, her family informed me that she had fallen down her basement stairs and had been admitted to a local hospital because of severe bruising. There, pneu- monia developed and hematologic abnormalities were noted, and she had recently died.

The patient had consented to autopsy at this hospital during an earlier office visit. Therefore, the body was transferred to this hospital for an investigation of the cause of death and the cause of her longtime chronic pain. PATHOLOGICAL DISCUSSION Dr. Christian J.

Chambliss Harrod, a resident in orthopedic surgery. The spine was frozen at −80°C and cut axially into slices 2 mm to 4 mm thick. At many levels, we observed small, extradural, thin-walled cysts where the spinal nerve exited the spinal ca- nal (Fig. What is primary oral herpes? Sections of representa- tive cysts were stained with hematoxylin and eo- sin, which revealed that the cysts had thin walls (Fig. 2F and 2G) and were sitting within the nerve roots just proximal to the dorsal-root ganglia, with spinal-nerve fibers passing through them. Nerve twigs, confirmed by immunohistochemical anal- ysis for neurofilament protein, were embedded in the walls of the cysts (Fig.

3A and 3C). The cells lining the cysts were small and had wispy cyto- plasm, suggestive of perineurial cells, and were positive for GLUT1 (Fig. 3B) and claudin-1 (not shown), two well-characterized markers of peri- neurial cells. The cyst at the T7–T8 intervertebral space, which had been drained and injected with fibrin glue, had a more opaque appearance on gross examination than did the other cysts (Fig. Mangler M, Trebesch de Perez I, Teegen B, et al. Microscopical examination revealed increased septations but no inflammation, fibrosis, or foreign-body–type giant-cell reaction (Fig. 2H).

The location, gross appearance, and histo- logic characteristics of these cysts are the same as originally described by Tarlov in 1938 and in multiple subsequent reports.2,23,25,26 They are lo- cated just outside the spinal canal, where the spinal nerve penetrates the dura, they are intra- neural, and they abut the dorsal-root ganglia. In the absence of other anatomical or microscopical abnormalities, the multiple cysts in the sacral spine probably are responsible for the patient’s incontinence. A chronic myeloproliferative neoplasm, which had been diagnosed shortly before the patient’s death, involved multiple organs, including the bone marrow, liver, spleen, cardiac interatrial sep- tum, and lungs, and was the most likely cause of death.

with progressive neurologic deficits, these cysts can be treated surgically with good results. I would also like to thank the patient and her family for permitting the autopsy, a very thought- ful and understanding act on her part, which gave us the opportunity to learn more about a poorly understood condition. Dr. Oaklander: It is noteworthy that this first published pathological study of a fibrin-injected cyst showed no evidence of severe or chronic in- flammation, adhesions, or scarring, the presence of which might affect future surgical management.
