RESUMO
A total of 129 normal computed tomograms of the chest was retrospectively reviewed to determine the appearance and frequency of visualization of the inferior pulmonary ligament. The ligament was seen on the left in 67.4% of patients, on the right in 37.2% of patients, on both sides in 27.1% of patients, and on neither side in 22.4% of patients. Of those ligaments seen, 92% on the left and 92% on the right demonstrated a posterior orientation. Examples are shown emphasizing the importance of the inferior pulmonary ligament in relation to lower lobe collapse, pleural effusion, extension of a mediastinal abnormality into the ligament, and the possible intraparenchymal appearance of an abnormality located within the ligament.

Bone scintigraphy is a very useful technique for detection of aseptic necrosis. We have used this diagnostic tool in a patient to detect aseptic necrosis of the talus, a common complication stemming from foot injuries. The scintigraphic pattern is rather typical and antedates any other radiographic changes. This technique appears to be very useful for diagnosis and follow-up of aseptic necrosis occurring during talar injuries.
