Ovarian remnant syndrome (ORS) is a rare condition in which ovarian tissue persists at the site of prior oophorectomy and often causes debilitating pelvic pain. Gold standard of treatment is surgical resection. We report a case of persistent ORS in a 44-year-old female who was successfully treated with ovarian artery embolization after failure of standard medical and gynecologic therapies. The ovarian tissue remnant was reduced by 75% in volume, and the patient was near symptom-free four months after the procedure...

Kienböck disease typically presents with wrist pain, swelling, restricted range of motion, and difficulty in performing activities of daily living. Because the etiology and evolution of disease remain unclear, broad ranges of treatments have been designed. Percutaneous cementoplasty is expanding its role for managing painful bone metastases outside the spine. We can draw a parallel between lytic tumoral lesions and Kienbock's disease. Increasing the strength and rigidity of lunate with cementoplasty can prevent it from collapse, relieve the symptoms associated with the process of avascular necrosis, and increase the wrist range of motion...
