A case of polymyositis with repeated dysphagia and muscle weakness associated with peculiar findings of skin was reported. The patient was a 67-year-old man. His birth and development was normal. There was no family history of neuromuscular disease. On 26th March 1987 he was admitted to a hospital because of dysarthria and dysphagia after fever and diagnosed as having viral myositis. His conditions improved spontaneously with bed rest and he left hospital on 14th April. On 23rd April he had chill and sore throat with fever. On 27th he was admitted to the same hospital because of dysarthria and muscle weakness of the proximal portion of the upper limbs. These symptoms also improved with bed rest. He had repeated these symptoms several times and then he was admitted to our hospital on 12th June. On examination he showed the skin pigmentation under the right eye and the eruption in the back of hands and the buttocks. Muscle weakness was observed in the proximal portion of the upper limbs and the neck flexor. Laboratory tests in admission were as follows: sGOT 49 mU/ml, sGPT 104 mU/ml, LDH 1064 mU/ml, CPK 565 mM/ml, aldolase 25.2 IU/1/37 degrees C. Electromyography showed the typical myogenic changes and biopsy of left biceps brachii revealed inflammatory cells in the muscle fiber which are specific to polymyositis. Immuno-histochemical study is performed to analyse the subpopulation of mononuclear cells in biopsied muscle and skin. Mononuclear cells infiltrated into perimysium, endomysium and epidermis were positive for T11 and T8, but less positive for T4, B1 and Leu11. On the basis of these findings he was diagnosed as having "polymyositis syndrome".

CASE DESCRIPTION A 16-month-old neutered male Continental Giant rabbit (Lepus curpaeums) was referred for evaluation of a 7-day history of acute-onset, progressive, symmetric paraparesis. CLINICAL FINDINGS On initial examination, the rabbit was nonambulatory, and results of neurologic examination were consistent with a lesion affecting the T3-L3 spinal cord segments. Thoracic radiography showed irregular widening of the left T11-12 articular process joint. Marked dorsolateral and lateral extradural spinal cord compression with contrast enhancement of the adjacent epaxial muscles was evident on MRI images of the spine. TREATMENT AND OUTCOME A left-sided T11-T12 hemilaminectomy was performed, which revealed an abnormal and hypertrophic T11-12 articular process joint and an osteolytic lesion communicating with the vertebral canal. Copious purulent material causing marked spinal cord compression was evident, and the surgical site was lavaged extensively with sterile (0.9% NaCl) saline solution. Results of aerobic, anaerobic, and enriched bacteriologic cultures of swab specimens obtained from the surgical site were negative. Histologic analysis of biopsy samples revealed chronic purulent osteomyelitis, myositis, and fasciitis with necrosis, fibrosis, and dystrophic mineralization. The rabbit was discharged 48 hours after surgery. Ten weeks after surgery, the rabbit was ambulatory with mild paraparesis. On telephone follow-up 21 months after surgery, the owners indicated that the rabbit was healthy and expressed satisfaction with the treatment and outcome. CLINICAL RELEVANCE Paraspinal abscess with vertebral canal involvement should be considered as a differential diagnosis for rabbits with clinical signs of progressive T3-L3 myelopathy. Outcome for the patient of the present report suggested that surgical treatment including decompression and debridement can result in a favorable long-term outcome.
