The healthcare provider suspects Paget's disease in a patient. Which imaging modality is most useful for assessing the extent and severity of bone involvement?
X-ray
Computed tomography (CT) scan
Magnetic resonance imaging (MRI)
Bone densitometry (DXA scan)
The Correct Answer is A
X-rays are the most useful imaging modality for assessing the extent and severity of bone involvement in Paget's disease. X-rays can reveal the characteristic bony overgrowth and thickening, as well as any bone deformities and fractures.
b. Computed tomography (CT) scan: CT scans can provide detailed images of bones and soft tissues, but they may not be the initial choice for evaluating Paget's disease. X-rays are more specific for the condition.
c. Magnetic resonance imaging (MRI): While an MRI can provide detailed images of bones and soft tissues, it may not be the first-line imaging choice for evaluating Paget's disease. X-rays are more specific for bone involvement.
d. Bone densitometry (DXA scan): Bone densitometry is used to assess bone mineral density and is commonly used for conditions like osteoporosis. It may not provide the necessary information for evaluating Paget's disease.

Correct Answer is B
Explanation
A potential complication of Paget's disease is an increased risk of pathologic fractures. The abnormal bone remodeling weakens the bones, leading to an increased susceptibility to fractures.
a. Hypertension: Hypertension is not a direct complication of Paget's disease. The condition primarily affects bone structures.
c. Hyperthyroidism: Hyperthyroidism is not associated with Paget's disease. It is a separate condition related to thyroid gland dysfunction.
d. Type 2 diabetes mellitus: Type 2 diabetes mellitus is not a complication of Paget's disease. The conditions are unrelated and have different underlying causes.
Correct Answer is D
Explanation
The most common clinical manifestation of Paget's disease is bone pain and deformities due to abnormal bone remodeling and increased bone turnover.
a. Severe joint pain: While joint pain can occur in Paget's disease due to bone involvement, it is not the most common manifestation. Bone pain and deformities are more characteristic.
b. Unexplained weight loss: Unexplained weight loss is not a typical symptom of Paget's disease. It is not directly related to the bone disorder.
c. Visual disturbances: Visual disturbances are not associated with Paget's disease. This condition primarily affects bones, not the eyes or vision.
