概要
BACKGROUND
A 50-year-old man with a history of hyperlipidemia and hypertension presented to an emergency department after 10 days of fevers (temperature 40 degrees C), headache, malaise, myalgia, poor appetite, diarrhea, and weight loss of 6.35 kg. He would subsequently develop bilateral scrotal swelling and pain during his evaluation.
METHODS
Physical examination, CBC, blood chemistry panel, measurement of erythrocyte sedimentation rate and C-reactive protein level, liver function profile, urinalysis, lumbar puncture, blood cultures, urine cultures, cerebrospinal fluid culture, stool analysis and cultures, multiple viral studies including hepatitis serologies, measurement of antineutrophil cytoplasmic autoantibody levels, urine protein electrophoresis, serum protein electrophoresis, CT of the head, chest, abdomen and pelvis, MRI of the brain, temporal artery biopsy and pathologic analysis, scrotal ultrasonography, right spermatic cord biopsy and pathologic analysis.
METHODS
Polyarteritis nodosa with involvement of both spermatic cords.
RESULTS
Prednisone 60 mg daily was started for presumed temporal arteritis, but was discontinued when no evidence of arteritis was found in the temporal artery biopsy specimen. When pathologic analysis of the spermatic cord biopsy tissue confirmed polyarteritis nodosa, prednisone 40 mg twice daily was administered and the patient's scrotal pain and swelling resolved quickly. Steroids were slowly tapered and discontinued over the next 18 months. He remained free of systemic symptoms, with normal results on physical examination and laboratory evaluation, including urinalysis, CBC, erythrocyte sedimentation rate and C-reactive protein level, 5.5 months after discontinuation of glucocorticoid therapy.
