The characteristic imaging features of chronic thromboembolic pulmonary hypertension are described. This is a very rare disorder; prompt surgical treatment affords good results. The complementary use of the ventilation/perfusion scan and CT pulmonary angiogram in diagnosis, and exclusion of other differential diagnoses, are emphasised. (J HK Coll Radiol 2002;5:39-42)
