18 Sensory system: Touch, pain, temperature, vibration and joint position sense normal. Gait and co-ordination could not be assessed. Spine and skull: normal and no tenderness.

19 CVS: S1 S2 heard, no murmurs. R S: B/L NVBS, no added sounds. P/A: soft, non tender, bowel sounds present.

20 PROVISIONAL DIAGNOSIS CHRONIC INFLAMMATORY DEMYELINATING POLYNEUROPATHY.

21 INVESTIGATIONS Complete blood count: WBC: 10,000cells/cumm RBC: 3.5millions/cumm HB%:10.6gm% PC: 2.5 lakh/cumm Peripheral smear: Microcytic hypochromic anemia. Urine routine: Normal Blood Urea: 20mg/dl Serum Creatinine: 0.9mg/dl

22 ESR : 140mm/hr Creatinine phosphokinase : 52U/L C R P : Negative HbsAg : negative HIV I and II : negative VDRL : negative

23 RA factor: Negative Nerve conduction studies: 1. Bilateral median and ulnar nerve inexcitable and sensory conduction normal. 2. Bilateral common peroneal nerve very low to absent sensory motor action potential.

24 3. Bilateral sural and superficial peroneal nerve absent sensory motor action potential. Suggestive of pure motor neuropathy in upper limb. Bilateral common peroneal, sural and superficial peroneal axonopathy in lower limb. Suggestive of mononeuritis multiplex.

25 MONONEUROPATHY MULTIPLEX Diabetes Polyarteritis nodosa and other inflammatory angiopathic neuropathies Mixed cryoglobulinemia Sjogren sicca syndrome

26 Sarcoidosis Ischemic neuropathy with peripheral vascular disease. Lyme disease

27 CSF Analysis: Volume 1.5ml Cell Count: 02cells/cumm Cell Type : Lymphocytes Negative for malignant cells LDH : 96IU/L Glucose : 63mg/dl Protein : 214.2mg/dl

28 ANA PROFILE: RO 52 POSITIVE panca : Negative canca : Negative

29 Nerve Biopsy : left sural nerve: S/O VASCULITIC NEUROPATHY Biopsy shows transmural infiltrate around nutrient vessel composed of lymphocytes, histiocytes. Dense inflammation also seen around small epineurial arterioles and venules sparing endoneural vessels. There is no neovascularisation. Myelinated fiber loss appears multifocal non uinform, in sectorial pockets. Axonal regenaration is present with secondary demyelination. Occasional fibers show acute myelin degeneration.

32 DIAGNOSIS ISOLATED VASCULITIC PERIPHERAL NEUROPATHY.

33 TREATMENT Injection Methylprednisolone 1gm OD. Tablet Amlong 5mg BD. Tablet Metoprolol 50mg BD. Tablet Prazosin 2.5mg BD. Physiotherapthy.

34 TREATMENT Tablet Hydroxychloroquine 100mg BD. Tablet Methotrexate 7.5mg once a week. Tablet Amitryptaline 25mg OD. Tablet Pregabalin 75mg OD.

35 DISCUSSION A full description of the syndrome of peripheral neuropathy due to vasculitis without any manifestations of vasculitis in other systems was first made by Dyck et al. in L. MATHEW et al. Department of Neurology, Radcliffe Infirmary, Oxford, Bristol, UK. Vasculitis restricted to the peripheral nervous system (PNS), referred to as nonsystemic vasculitic neuropathy (NSVN).

36 DISCUSSION Vasculitis of the peripheral nervous system (PNS) is rare. There are no controlled treatment trials, and clinical practice is guided by experience from case series and indirectly by analogy with systemic vasculitis. Of 106 cases, 95 had systemic vasculitis and 11 had vasculitis confined to the PNS.

38 DISCUSSION M. P.COLLIN et al.department of Neurology, Medical College of Wisconsin, Milwaukee, Wisconsin, USA. All vasculitic neuropathies are axonal by electrodiagnostic/pathologic criteria. Laboratory testing is unremarkable except for mildly elevated erythrocyte sedimentation rate (ESR) in 50%. Highly elevated ESRs, leukocytosis, rheumatoid factors, and antineutrophil cytoplasmic antibodies (ANCAs) raise concern for underlying systemic vasculitis. Without a specific clinical/laboratory marker, the condition depends on nerve biopsy for diagnosis.

39 CONCLUSION Incidence: 10-15% Isolated vasculitis affecting the peripheral nerves can have an indolent presentation and may not be recognizable as mononeuritis multiplex by the time a patient presents. It can only be diagnosed with certainty on nerve biopsy and a firm diagnosis provides the basis for therapy that is likely to provide a clear benefit to the patient.

40 CONCLUSION It should be considered in any patient who presents with a progressive sensory and motor neuropathy where a definite cause cannot be established.

41 TAKE HOME MESSAGE Nerve biopsy is the gold standard test for isolated vasculitis of peripheral nervous system. Nerve biopsy is frequently delayed or avoided as it is an invasive procedure. Vasculitis is not often suspected as an etiological cause for neuropathy in the elderly.
