The sonographic appearances of four intramuscular myxomas were reviewed. These tumors appeared as well‐defined, ovoid masses surrounded by normal muscle. The echogenicity was decreased in all cases, and the presence of small fluid‐filled clefts and cystic areas was noted in three of the four lesions. Color Doppler examination was performed in two cases and was negative. Sonographically guided fine‐needle aspiration biopsy yielded a thick myxoid substance. Large‐core cutting needle biopsy allowed establishment of the diagnosis in one of the two cases in which it was performed. The differential diagnosis of a well‐demarcated intramuscular mass with multiple fluid‐filled clefts or cystic areas should include intramuscular myxoma.
