![]() ![]() Occasionally, a palpable radial artery pulse will accompany radiovolar ganglion cysts. Lesions of the flexor tendon tenosynovial sheath are usually found on the volar aspect of the metacarpophalangeal joint region and are pebblelike and firm to palpation. Physical examination typically reveals a soft mass with a cystic consistency to palpation that may transilluminate with a penlight. Complaints of pain range from none or minimal to severe and incapacitating, and it is not uncommon for the patient to report changes in lesion size prior to seeking examination. Ganglion cysts can occur after varying degrees of trauma, including contusions or twisting and stretching injuries, but it is not unusual to have the patient report an insidious onset. Ganglion cysts of all types are more common in women than in men by a ratio of 3-to-1 and have been reported in children. The dorsal wrist ganglion is the most frequently seen (60%-70% of all ganglion cysts) followed by volar wrist ganglions and cysts of the flexor and extensor tendon sheaths. Originally described as mucoid degenerations, it is now believed that these cysts can result from chronic irritation and stretching of joint capsules and other supporting tissues. Although subdermal, they are usually visually apparent, and their location and consistency on palpation result in accurate diagnosis in nearly every patient. Ganglion cysts are among the most common of the hand and wrist cystic masses. Treatment decisions in all cases should be based on the “golden rule” of hand surgery-“function over cosmesis.” Patients may insist on intervention for minor lesions and need to be reminded that there are risks, including unsightly scarring, to every surgical procedure.This article, the first of two installments, will focus on the most obvious benign and malignant bumps of the hand and wrist. Attempted needle aspiration often punctures the artery. A radiovolar ganglion cyst with radial artery passing over its central point. ![]()
