Figure 3: a-c (a and b) Two chest X-rays on a 30-year old man of African descent presented with dry cough and fatigue. The X-rays, a few days apart show bilateral hilar prominence and vague shadowing at the lung bases. (c) Axial CT scan on the same patient seen on a mediastinal setting shows two large nodules/areas of consolidation at the left lung base. (d) Axial high resolution CT scan covering the lung bases shows lung masses/consolidation and ground glass attenuation. The blood count and biochemistry was normal, but the angiotensin-converting-enzyme levels were elevated at 71 IU/L. A diagnosis of pulmonary sarcoidosis was made. Patients responded completely to steroid treatment
