Imaging
- Sarcoidosis mimicking lytic osseous metastases
Sarcoidosis involves the lung in more than 90% of cases; skeletal involvement has been reported in 1% to 14%.
- Ring-enhancing cerebral lesions
The patient has poorly controlled HIV, seizures, and brain lesions. Is Histoplasma or Toxoplasma the cause of the lesions?

Constrictive pericarditis due to secondary hyperparathyroidism occurs in up to 4% of patients with end-stage renal disease.

Back “in the day,” the giants of medicine relied on old-fashioned skills; today, we have an upgraded set of tools.
- Hypertrophic osteoarthropathy: Uncommon presentation of lung cancer
The patient presented with bilateral ankle joint pain, swelling of the ankles and wrists, and digital clubbing.
