Show ORIGINAL CONTRIBUTION Optic Neuropathy Associated With Periostitis in Relapsing Polychondritis Parima Hirunwiwatkul, MD and Jonathan D. Trobe, MD Abstract: Optic neuropathy is an uncommon manifestation of relapsing polychondritis ( RPC), a rare systemic disease affecting cartilaginous and proteoglycan- rich structures. The optic neuropathy has been attributed to ischemia, intrinsic inflammation of the optic nerve, or spread of inflammation to the nerve from adjacent intraconal orbital tissues. We report a case of recurrent corticosteroid- responsive optic neuropathy in which MRI did not show ocular, optic nerve, or intraconal orbital abnormalities but did show periosteal thickening and enhancement in the apical orbit and adjacent intracranial space consistent with periostitis. The periostitis, which is a manifestation of a systemic vasculitis or an autoimmune reaction to progenitors of cartilage, probably caused the optic neuropathy by compression or inflammation. It is important to recognize this mechanism of optic neuropathy as its imaging features may be a subtle yet critical clue to an underlying systemic condition that can be life- threatening if not properly managed. (/ Neuro- Ophthalmol 2007; 27: 16- 21) Relapsing polychondritis ( RPC) is a rare multisystem disease affecting cartilaginous tissue and proteoglycan-rich structures such as the eye, heart, blood vessels, and inner ear ( 1). Several reports support autoimmunity to collagen types II, IX, and XI and other cartilaginous protein ( 2,3). In RPC, the major causes of death are pulmonary infection and respiratory collapse, renal failure, and cardiac valvular complications ( 1,4). Common ophthalmic manifestations include conjunctivitis, episcleritis, uveitis, and scleritis. Inflammatory orbitopathy and optic neuropathy have been reported rarely ( 5). The mechanism of optic neuropathy is believed to be ischemia, intrinsic Kellogg Eye Center, Department of Ophthalmology and Visual Sciences ( PH, JDT), and Department of Neurology ( JDT), University of Michigan, Ann Arbor, Michigan.

We report a case of RPC with optic neuropathy apparently caused by an extraconal process, namely inflammation of the periorbita (" periostitis"), a mechanism not previously recognized. CASE REPORT A 78- year- old woman had new onset of acute painless visual loss in the left eye. She denied fever, jaw claudication, weight loss, muscle pain, joint pain, or lethargy. However, she had had six bouts of redness, pain, and tenderness of either ear and of the dorsum of her feet over the past 4 years. Her primary care physician attributed the ear and foot lesions to granuloma annulare, a benign papular skin eruption that does not, however, involve the ear. Each episode would resolve within days after treatment with 10- 20 mg prednisone daily. There was also a history of chronic hypertension for which she had been treated with a combination of hydrochlorothiazide and bisoprolol. Examination elsewhere disclosed a best- corrected visual acuity of 20/ 25 in the right eye and 20/ 70 in the left eye. An afferent pupillary defect was present in the left eye with a swollen left optic disc. Humphrey visual fields showed nerve fiber bundle defects in both eyes with mean deviations of - 5.6 db and - 5.8 db. The rest of the ophthalmic examination was reported as normal. An erythrocyte sedimentation rate ( ESR) was 60 mm/ h. A temporal artery biopsy was negative. She received a diagnosis of optic neuritis in the left eye of uncertain cause and was treated with 60 mg prednisone daily over 2 weeks. Visual acuity dramatically improved within 3 days of starting treatment and was recorded at 20/ 25 in both eyes 1 month later with resolution of optic disc edema in the left eye. Three months later, she complained of left periocular pain and diminished vision in the left eye. Visual acuity was reported as 20/ 30 in the right eye and 20/ 100 in the left eye. The left optic disc was reported to be slightly swollen again. She was diagnosed with recurrent optic neuritis and retreated with 60 mg oral prednisone daily. Within days she noted visual improvement. Visual acuity was recorded 16 J Neuro- Ophthalmol, Vol. 27, No. 1, 2007 Optic Neuropathy in Relapsing Polychondritis J Neuro- Ophthalmol, Vol. 27, No. 1, 2007 FIG. 1. A, B. Midorbital T1 coronal MRI.

Our examination 1 week later revealed a best-corrected visual acuity of 20/ 20 in both eyes. Visual fields showed mean deviations of - 0.67 db and - 1.72 db with scattered high threshold points but no obvious nerve fiber bundle defects. Pupils were normal in size and reactivity and displayed no afferent defect. The right optic disc was normal, but the left optic disc still showed mild swelling. There were no other neurologic deficits and no evidence of inflammation of her ears or feet. Brain and orbit MRI showed enhancement and thickening of the periosteum within the orbital apices and the adjacent intracranial meninges, especially on the left side ( Fig. 1). There was no thickening or enhancement of either optic nerve or other intracranial abnormalities. Standard laboratory studies for an inflammatory disorder, including angiotensin- converting enzyme ( ACE), antinuclear antibodies ( ANA), dilute Russell viper venom, and coarse granular antineutrophil cytoplasmic antibodies ( c- ANCA), were negative. The only positive test was perinuclear antineutrophil cytoplasmic antibodies ( p- ANCA). FIG. 2. A. The right ear is red and swollen during a relapse of polychondritis. B.

CT scans of the abdomen and pelvis were negative. An echocardiogram showed minimal mitral, tricuspid, and pulmonic regurgitation accompanied by pulmonary hypertension. Chest x- ray was normal, but CT scanning of the chest showed multiple lung nodules. Bronchoscopic biopsy revealed fragments of bronchial wall with thick sclerotic vessels consistent with pulmonary hypertension. Visual function remained unchanged without treatment during a follow- up period of 8 months. Repeat MRI performed 1 month and 5 months after our first consultation showed no change. However, she developed recurrent inflammation ( Fig. 2) affecting either the right or left ear but sparing the earlobe that always resolved within days after treatment with 10- 20 mg prednisone daily for 1 week. A presumptive diagnosis of RPC was made. DISCUSSION Our patient with RPC displayed recurrent unilateral optic neuropathy that appeared to be responsive to oral corticosteroid treatment. There were no clinical or imaging signs of inflammation of the eyes or intraconal orbital tissues. MRI showed thickening and enhancement of the apical periorbita and adjacent intracranial meninges, probably reflecting inflammation. We presume that the recurrent optic neuropathy was caused by compression of the apical optic nerve or inflammation of its dural covering. Neither intracranial dural nor periosteal inflammation has been described in RPC. There have been 25 reported cases of optic neuropathy in RPC, 12 of which are derived from one review of ophthalmic manifestations of RPC and 13 from other single or double case reports ( 3,6- 18). The optic neuropathy has been labeled as " optic neuritis" ( ON), " anterior ischemic optic neuropathy" ( AION), or " papilledema." Although most reports do not provide enough detail to ascertain the precise mechanism, it has been presumed to be inflammatory ( ON) if the vision improved with antiinflammatory treatment and ischemic if it did not ( Table 1). Based on our review of reported case material for which there is enough detail, we would designate 4 cases as ischemic, 13 as inflammatory, and 8 of indeterminate mechanism. Imaging was available in only 2 cases. In one of these, CT scanning showed attenuation of orbital fat signal and intraconal biopsy- proven lymphoid hyperplasia ( 13); in the other, biopsy- proven mucosa- associated lymphoid tissue ( MALT) ( 14) appeared to deform and perhaps infiltrate the optic nerve. To our knowledge, the periosteal inflammation (" periostitis") seen in our patient has not been reported 19 J Neuro- Ophthalmol, Vol. 27, No. 1, 2007 Hirunwiwatkul and Trobe in RPC, but it has been reported in other connective tissue or vasculitic disorders such as polyarteritis nodosa ( 19,20), sarcoidosis ( 21), and lupus erythematosus ( 22,23). In these disorders, vaso- occlusion is believed to cause hypoxia with release of bone- derived growth factors that induce inflammation of the periosteum ( 20). Why might the periosteum be a target in RPC? Vaso-occlusion may result from immune complex attachment, as occurs in scleral vessels in RPC ( 16). Another possible mechanism is an autoimmune reaction to damaged periosteum, which has been reported to contain collagen type II, a progenitor of cartilage ( 24,25). The chondroge-nicity of the periosteum arises because the cambium layer of the periosteum contains chondrocyte precursor cells that form cartilage during limb development and growth in utero and does so once again in injured periosteum during fracture healing ( 26- 28). A third possible mechanism for periostitis in RPC is a limited form of pachymeningitis. Focal pachymeningitis has not been described in RPC, but there have been reports of what seems to be leptomeningeal involvement as part of " aseptic meningitis" ( 29- 32), " migratory leptomeningeal inflammation" ( 33), and " meningoencephalitis" ( 34,35). These manifestations may be part of an autoimmune reaction to collagen type II, a minor component of the dura and notochord remnants ( 36). Moreover, pachymeningitis is reported in conditions similar to RPC, including rheumatoid arthritis ( 37- 39), Wegener granulomatosis ( WG) ( 40,41), and p- ANCA- positive microscopic polyangiitis ( 42- 46). Indeed, WG ( 47,48), ankylosing spondylitis ( 49), lupus ( 50), and Behcet disease ( 51) have been reported to manifest auricular chondritis. Given that we did not obtain tissue, did our patient actually have RPC or one of these other autoimmune disorders? We believe our diagnosis of RPC is justified on the basis of the modified McAdam criteria, which specify the presence of chondritis at two or more separate anatomic locations with response to corticosteroids or dapsone ( 52- 54). She also had mitral valve regurgitation, which has been reported in RPC ( 55,56). Finally, there was no serologic support for WG or alternative diseases. In conclusion, our patient showed a previously undocumented mechanism of optic neuropathy. Recognizing this mechanism is important for two reasons: 1) orbitocranial imaging features may be subtle, and 2) the diagnosis of RPC is critical because its effects on other cartilaginous and proteoglycan tissues may be life-threatening if not properly managed.
