55-year-old female with palpable left thyroid mass. RIGHT LOBE MEASUREMENTS: 5.6 x 1.6 x 1.8 cmLEFT LOBE MEASUREMENTS: 5.7 x 2.3 x 2.7 cmISTHMUS MEASUREMENTS: 0.3 cmRIGHT LOBE: Overall echotexture is homogeneous. There is 0.4 x 0.4 x 0.7 cm spongiform-appearing nodule in the upper pole. Small, benign cystic lesion in the lower pole.LEFT LOBE: Echotexture is homogeneous. There is a 2.3 x 2.7 x 3.7 cm predominantly cystic mass in the left lobe corresponding to the palpable abnormality. There are 2 focal areas of nodular wall thickening, the largest measuring 0.4 burs x 0.8 cm without obvious flow by color Doppler. Wall is otherwise smooth without significant thickening. Slightly cephalad there is a smaller cystic area without definite solid component. ISTHMUS: No significant abnormality noted.PARATHYROID GLANDS: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.OTHER: No significant abnormality noted.
Small, likely colloid nodules right lobe. Dominant complex cystic mass left lobe. Given the large size of the cystic component and small nodular components, this likely represents a complex colloid cyst. Biopsy was not performed due to the high likelihood of a nondiagnostic sample. If aspiration is desired, patient can easily be rescheduled. This was discussed with the patient.
