Explanation:

Hydroxyapatite deposition disease (HADD) is characterized by the deposition of hydroxy - apatite crystals in soft - tissue structures such as tendons and bursae. On radiographs, it typically appears as amorphous or cloud - like calcifications in these areas. Geographic lytic lesions with sclerotic borders are more characteristic of certain bone tumors or infections. Linear calcification in joint cartilage is seen in chondrocalcinosis. Hook - like osteophytes in MCP joints are related to osteoarthritis.

Answer:

D. Amorphous or cloud - like calcifications in tendons or bursae
