Question

Quizplus · Accepted Answer

Hyperparathyroidism can cause increased calcium release from bones, leading to decreased bone density and cystic bone defects. It can also cause renal calculi due to increased levels of calcium in the urine. Pseudohypoparathyroidism, on the other hand, typically presents with normal or increased bone density, and hypoparathyroidism presents with low calcium levels, which would not explain the cystic bone defects. Hypervitaminosis D can lead to increased calcium levels but would not explain the cystic bone defects.
