We found heterogeneous texture with hypoechogenic areas in the first four annual ultrasounds of the left parotid region (Figure 2A), in addition to increased intraparotid lymph nodes in the first two exams. These abnormalities were not evidenced in the last ultrasound, performed after 8 years without symptoms, which showed gland within the normal range (Figure 2B).
