a 35 - year - old male presents with progressive right shoulder pain. radiographs of the region reveal a homogeneous calcification adjacent to the greater tuberosity. what is the diagnosis?
a) calcium pyrophosphate deposition disease
b) gout
c) hydroxyapatite deposition disease
d) rotator cuff tear

Explanation:

Hydroxyapatite deposition disease often presents with pain (in this case, right - shoulder pain) and homogeneous calcification on radiographs. Calcium pyrophosphate deposition disease typically shows chondrocalcinosis. Gout is associated with urate crystal deposition (not homogeneous calcification as described). A rotator cuff tear would not present with homogeneous calcification adjacent to the greater tuberosity on radiographs.

Answer:

C. hydroxyapatite deposition disease
