PYOMYOSITIS - CERVICAL LOCALIZATION

We describe an uncommon case of cervical pyomyositis in a 60-year-old woman without predisposing factors, admitted for cervicobrachial neura lgia with fever and paravertebral contracture. Ultrasonography and com puted tomography (CT) showed a collection in the left longissimus capi tis. Ultrasonography guided needle aspiration yielded thick pus, which cultured Staphylococcus aureus. Our patient completely recovered afte r antibiotherapy. Pyomyositis is rare and most commonly affects rhizom elic muscles (cervical localization is extremely rare) and occurs in p atients with predisposing factors. Staphylococcus aureus is responsibl e for over 85% of cases; ultrasonography and CT scan are useful for ab scess localization and aspiration.
