Spontaneous pneumothorax secondary to sarcoidosis

Discussion:

This case shows a possible complication of sarcoidosis affecting the lung and pleura, as well as some typical image findings, such as:

  • perilymphatic nodules
  • lymphadenopathy: bilateral hilar, paratracheal, aortopulmonary window, subcarinal lymph nodes
  • lymph node calcification in chronic disease
  • Rupture of subpleural bullae or necrosis of subpleural granulomas are recognized causes of pneumothorax in sarcoidosis, occurring in only 2% of patients. Recurrence is possible, with some authors suggesting this as a manifestation of advanced disease.
