Figure 8 (A-G): Sarcoidosis with atypical manifestations. (A) Alveolar sarcoidosis: Magnified axial high resolution computed tomography (HRCT) image (lung window) shows ill-defined patchy consolidation in right upper lobe with multiple satellite nodules at the periphery-alveolar or acinar sarcoidosis. Note discrete perilymphatic nodules along right major fissure. (B and C) Sarcoidosis with GGO. (B) Axial HRCT image (lung window) in a patient with sarcoidosis showing diffuse areas of GGO bilaterally. Note nodular thickening of bronchovascular interstitium in left upper lobe (black arrow). (C) Axial CT image (mediastinal window) of the same patient showing discrete homogeneous bilateralhilar lymphadenopathy.(D) Sarcoidosis with miliary nodules. Axial HRCT image (lung window) in a patient with sarcoidosis shows multiple discrete nodules randomly distributed in bilateral lung parenchyma. Note bilateral hilar lymphadenopathy (black arrow). (E and F) Sarcoidosis with lower lobe predominance. Axial CT image (lung window) showing perilymphatic nodules and confluent perihilar masses with predominant lower lobe involvement bilaterally. (G) Sarcoidosis with asymmetric involvement. Axial HRCT image (lung window) in a patient with sarcoidosis shows perilymphatic micronodules and coalescent masses involving right lung
