Female 52 years old Reason: puncture wound 2/2 bite, r/o infection vs. fracture History: animal bite There is swelling of the soft tissues of the index finger. We see no fracture. There is a 1 mm round lucency in the base of the distal phalanx of the index finger, which appears to have thin sclerotic margins and is favored to represent a degenerative cyst. However, if there is strong clinical concern for penetration of bone and/or osteomyelitis, MRI may be considered for further evaluation. Osteoarthritis affects the interphalangeal joints.
