11 Erosion of Multiple
Terminal Phalangeal Tufts (Acro-
Osteolysis)
CLINICAL IMAGAGING
AN ATLAS OF DIFFERENTIAL DAIGNOSIS
EISENBERG
DR. Muhammad Bin Zulfiqar
PGR-FCPS III SIMS/SHL
โ€ข Fig B 11-1 Raynaud's disease. Severe trophic
changes involve the distal phalanges with
resorption of the terminal tufts.
โ€ข Fig B 11-2 Diabetic gangrene. Diffuse
destruction of the phalanges and the
metatarsal head of the fifth digit. Note the
large amount of gas in the soft tissues of the
foot.
โ€ข Fig B 11-3 Psoriatic arthritis. Arthritis mutilans
of the foot and ankle. Severe pencil-like
destruction of the metatarsals and phalanges
with ankylosis of almost all the tarsal joints.
โ€ข Fig B 11-4 Leprosy. Severe phalangeal
resorption with evidence of typical pencil-like
configurations.
โ€ข Fig B 11-5 Hyperparathyroidism. Tuft resorption
associated with subperiosteal bone resorption
that predominantly involves the radial margins of
the middle phalanges of the second, third, and
fourth digits (arrows).
โ€ข Fig B 11-6 Lesch-Nyhan syndrome. Amputation of the
index and middle fingers from a self-inflicted bite.
Although the child is 5 years old, the bone age is that
of a 3-year-old.24
โ€ข Fig B 11-7 Epidermolysis bullosa. Diffuse
trophic changes about the distal phalanges
associated with bilateral contracture
deformities resulting in a claw hand. Note the
peculiar pointed, hook-like appearance of the
terminal phalanges of the thumbs.25
Fig B 11-8 Progeria. Progressive absorption of the ungual tufts
with preservation of soft tissues occurring over a 5-year period.26
Fig B 11-9 Familial acro-osteolysis. Characteristic band-like areas
of lucency crossing the waists of several phalanges.
โ€ข Fig B 11-10 Pachydermoperiostosis. Elephant-like thickening of the
skin causes clubbing of the distal fingers and exaggerated knuckle
pads in addition to a generalized increase in the bulk of the soft
tissues surrounding the phalanges. Loss of the tufts accompanies
the increase in the overlying soft tissues.19

11 erosion of multiple terminal phalangeal tufts (ACROOSTEOLYSIS)

  • 1. 11 Erosion of Multiple Terminal Phalangeal Tufts (Acro- Osteolysis)
  • 2. CLINICAL IMAGAGING AN ATLAS OF DIFFERENTIAL DAIGNOSIS EISENBERG DR. Muhammad Bin Zulfiqar PGR-FCPS III SIMS/SHL
  • 3. โ€ข Fig B 11-1 Raynaud's disease. Severe trophic changes involve the distal phalanges with resorption of the terminal tufts.
  • 4. โ€ข Fig B 11-2 Diabetic gangrene. Diffuse destruction of the phalanges and the metatarsal head of the fifth digit. Note the large amount of gas in the soft tissues of the foot.
  • 5. โ€ข Fig B 11-3 Psoriatic arthritis. Arthritis mutilans of the foot and ankle. Severe pencil-like destruction of the metatarsals and phalanges with ankylosis of almost all the tarsal joints.
  • 6. โ€ข Fig B 11-4 Leprosy. Severe phalangeal resorption with evidence of typical pencil-like configurations.
  • 7. โ€ข Fig B 11-5 Hyperparathyroidism. Tuft resorption associated with subperiosteal bone resorption that predominantly involves the radial margins of the middle phalanges of the second, third, and fourth digits (arrows).
  • 8. โ€ข Fig B 11-6 Lesch-Nyhan syndrome. Amputation of the index and middle fingers from a self-inflicted bite. Although the child is 5 years old, the bone age is that of a 3-year-old.24
  • 9. โ€ข Fig B 11-7 Epidermolysis bullosa. Diffuse trophic changes about the distal phalanges associated with bilateral contracture deformities resulting in a claw hand. Note the peculiar pointed, hook-like appearance of the terminal phalanges of the thumbs.25
  • 10. Fig B 11-8 Progeria. Progressive absorption of the ungual tufts with preservation of soft tissues occurring over a 5-year period.26
  • 11. Fig B 11-9 Familial acro-osteolysis. Characteristic band-like areas of lucency crossing the waists of several phalanges.
  • 12. โ€ข Fig B 11-10 Pachydermoperiostosis. Elephant-like thickening of the skin causes clubbing of the distal fingers and exaggerated knuckle pads in addition to a generalized increase in the bulk of the soft tissues surrounding the phalanges. Loss of the tufts accompanies the increase in the overlying soft tissues.19
