A female patient, 66 years old who goes to his doctor for tumor presenting as painful spontaneous movements in the distal interphalangeal joint of the right thumb .The doctor tells her it is a cyst and would have to operate but it requires an assessment cardiovascular, primarily because of his age. When he examines the cardiologist is a disturbance of heart rhythm (bradycardia), so that tells you about analysis and sonographic examination of the thyroid.
Thyroid sonography showed multiple solid nodular lesions in both lobes, accompanied by a few micro-cysts.
The sonographic images in this issue relate to the injury "cystic" of the distal phalanx of right thumb, where an image is displayed, echogenic, containing liquid, located in the interphalangeal joint of the thumb, which corresponds to right thumb ganglion. The lesion measures 1.2 X 1.0 X 0.4 cm. This lesion is similar to that previously described by us in the wrist of a patient (see ganglion cyst of the wrist) .
