A 35-year-old woman is evaluated in the office for a 5-month history of right-hand numbness and tingling. She says that these symptoms involve the entire hand, seem to be worse when she drives or holds a book or newspaper, and have been awakening her at night. She reports no history of neck pain or hand weakness. Personal and family medical histories are noncontributory, and she takes no medication. General physical examination reveals no abnormalities. Neurologic examination shows normal strength but sensory loss in the first three digits and the radial half of the fourth digit in the right hand. Which of the following is the most likely diagnosis?
(A) Carpal tunnel syndrome
(B) de Quervain tenosynovitis
(C) Ganglion cysts
(D) Ulnar nerve compression (Guyon tunnel syndrome)
