DIAGNOSIS: Pisiform recess and radiocarpal joint
ANSWER: Pisiform recess and radiocarpal joint
EXPLANATION:
The pisiform recess and radiocarpal joint normally communicate. Increased fluid in the pisotriquetral joint should not be considered abnormal if there is fluid within the radiocarpal joint (similar concept as having fluid in the biceps tendon sheath in a patient with a glenohumeral joint effusion). Both of these sites may be used for a wrist arthrogram. There may be no communication between the radiocarpal joint and the pisotriquetral joint in 12-25% of patients.
