Systemic-to-pulmonary collateral vessels and shunts develop in patients with isolated unilateral absence of a pulmonary artery (IUAPA). Two cases of IUAPA (right and left) with hemoptysis in adult life are presented. Selective embolization of these systemic vessels controlled hemoptysis successfully. These cases represent an example of an alternative treatment for this rare anomaly.

The CT and MR appearance of giant cavernous hemangiomas can be confusing, and some atypical radiographic findings have been described. We report the CT and MR features of a giant cavernous hemangioma of the liver with atypical presentation. CT showed a large hypodense geographical lesion involving the majority of the liver and multiple scattered peripheral lesions. The T2-weighted MR images revealed a huge hyperintense lesion with multiple satellite nodules.

Amyloidomas involving bone are rare. The 67-year-old man reported here had a large amyloidoma of the left frontal, parietal, sphenoid (greater wing) and temporal bones causing neural compression. Plain radiographs CT and MRI are shown.

A case of duodenal obstruction by biliary calculus associated with esophageal rupture is described. CT demonstrated air in the gallbladder, an impacted gallstone in the duodenum, pneumomediastinum, and hydropneumothorax. The present report describes the CT findings of these two rare conditions in the same patient.
