RadiologyHyperparathyroidism is a condition characterized by an
overproduction of parathyroid hormone (PTH), which leads to increased bone
resorption and changes in bone density. The radiographic features associated
with hyperparathyroidism include:
Loss of Lamina Dura: The lamina dura is the thin layer
of dense bone that lines the tooth socket (alveolus). In
hyperparathyroidism, the loss of lamina dura can be observed due to the
increased osteoclastic activity and bone resorption.
Ground Glass Appearance: This refers to a radiographic
appearance of bone that looks hazy or "ground glass" rather than having a
clear, well-defined structure. This appearance is due to the alteration in
bone density and the presence of fibrous tissue replacing normal bone.
Other Options:
Osteogenesis Imperfecta: This condition is characterized
by brittle bones due to a defect in collagen formation. Radiographically, it
may show thin cortices and osteopenia, but not typically a ground glass
appearance.
Osteopetrosis: This is a condition of excessive bone
density due to impaired osteoclast function. Radiographically, it shows
increased radiopacity (dense bones) rather than a ground glass appearance.
Osteitis Deformans (Paget's Disease): This condition is
characterized by disorganized bone remodeling. Radiographically, it can show
a "cotton wool" appearance and enlarged bones, but it does not typically
present with a loss of lamina dura or a ground glass appearance in the early
stages.
