Description
In the 1980s, a woman in her 40s started noticing that her hats were not fitting. She also reported suffering from headache, hearing loss and tinnitus. Alkaline phosphatase and urinary hydroxyproline levels were raised in the beginning. She was diagnosed with Paget's disease.
She was started on calcitonin treatment and when available, a few years later, bisphosphonates.1
Paget's disease is a localised disorder of bone remodelling that typically begins with excessive bone resorption followed by an increase in bone formation. This leads to a structurally disorganised mosaic of bone, which is mechanically weaker, larger, less compact, more vascular and more susceptible to fracture.
After three decades, the skull bones grew as seen in figures 1 and 2.
This case report shows the evolution of the disease for more than 30 years, despite the available treatment at times. Over a period of time, the disease remained monostotic (figure 3).
Paget's disease may involve a single bone but is more frequently multifocal with a predilection for the axial skeleton; however, any bone may be affected.
After onset, Paget's disease does not spread from bone to bone, but it may become progressively worse at pre-existing sites.
Currently, there are no signs of activity of the disease.
Learning points
-
Although rare, headaches associated with hearing loss, enlargement or bowing of bones, tingling or numbness should lead one to suspect Paget’s disease.1
-
It is a chronic condition, focused on one or a few bones of the pelvis, back (spine), hips, thighs, head and arms,1 but rarely polyostotic.
-
Bisphosphonates are the first line of treatment for localised pain, which is thought to be due to increased bone metabolic activity and consequent increased circulation.1
-
Follow-up should focus on activity and complications: fractures, nervous system involvement or nerve entrapment, osteoarthritis or a coexisting musculoskeletal condition.1
