Churg-Strauss syndrome (CSS) is a rare systemic vasculitis that affect small and medium-sized blood vessels and is accompanied by asthma, eosinophilia, and peripheral neuropathy. This report describes a case of a 52-year-old man who had a history of sinusitis, asthma, and thymus cancer and who had complained of bilateral lower extremity paresthesia and weakness for a month. Peripheral neuropathy was detected by electrodiagnostic studies. Resection of a mediastinal mass, which was diagnosed as thymic neuroendocrine carcinoma, was performed five months before his visit. After thymectomy, peripheral blood tests revealed a gradual increase in eosinophils. Two months after surgery, he was admitted to the hospital for dyspnea, and nodules of focal consolidation were found in his chest X-ray. One month later, pyoderma occurred in the right shin, and the skin biopsy showed extravascular eosinophilic infiltration. He was diagnosed with CSS after thymectomy, and we report a very rare case of CSS presented with thymic neuroendocrine carcinoma.

Systemic vasculitis is a rare disease, and the diagnosis is very difficult when patient shows atypical symptoms. We experienced an unusual case of dysphagia caused by Churg-Strauss syndrome with lower cranial nerve involvement. A 74-year-old man, with a past history of sinusitis, asthma, and hearing deficiency, was admitted to our department for evaluation of dysphagia. He also complained of recurrent bleeding of nasal cavities and esophagus. Brain magnetic resonance imaging did not show definite abnormality, and electrophysiologic findings were suggestive of mononeuritis multiplex. Dysphagia had not improved after conventional therapy. Biopsy of the nasal cavity showed extravascular eosinophilic infiltration. All these findings suggested a rare form of Churg-Strauss syndrome involving multiple lower cranial nerves. Dysphagia improved after steroid therapy.

Churg-Strauss syndrome (CSS) is a rare systemic necrotizing vasculitis. Cranial nerve involvement is very rare in CSS. A 59-year-old woman had complained of both hearing impairments for eight months and left facial palsy for three months. Left facial and cochlear neuropathies were detected in electrodiagnostic studies. Paranasal sinus computed tomography (CT) showed chronic pansinusitis. Chest CT revealed eosinophilic infiltration in the right upper lobe. Tissue biopsy of the right inferior turbinate displayed necrotizing vasculitis with eosinophilic infiltration. She was diagnosed as CSS, based on the presence of eosinophilia, pulmonary infiltration, paranasal sinusitis, and biopsy containing blood vessels with extravascular eosinophils. She was treated with intravenous and oral steroids and azathioprine, showing relatively good prognosis on facial palsy and hearing impairment. We report a very rare case of CSS presented with hearing impairment and facial palsy.

Objective: We report a case of Churg-Strauss syndrome (CSS) which accompanied a mononeuritis multiplex.
Case Summary: A 46-year-old woman began to suffer from an allergic rhinitis since 1985, and was diagnosed as a bronchial asthma in 1995. She also complained numbness of the upper and lower extremities, which eventually lead to a weakness and edema of both upper and lower extremities. Electrophysiologic study findings were compatible with a mononeuritis multiplex. The skin biopsy revealed a necrosis of the vessels with infiltration of a large number of neutrocytes and lymphocytes.
Conclusion: Based on the patient's clinical characteristic, skin biopsy findings and electrophysiologic study findings, we have concluded that the case fit well for CSS.
