Abstract:
Metastatic pulmonary calcification (MPC) is an uncommon entity resulting from abnormalities in calcium-phosphorus homoeostasis. Most cases reported in the literature are among patients with chronic kidney disease receiving haemodialysis. Primary hyperparathyroidism is a relatively common condition affecting calcium homoeostasis, in which MPC can rarely occur. We report the case of one such patient who presented with severe hypercalcaemia and features of interstitial lung disease. Radiographic imaging was normal and the diagnosis was clinched by diffuse pulmonary uptake in 99mTechnetium-methylene diphosphate scan.

Unusual Results
According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.

z Scores and Unusual Values
This score indicates how far a value is from the mean in terms of standard deviation. For example, if a data value has a z score of +1, the researcher can infer that the particular data value is one standard deviation above the mean. If another data...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
