Early diagnosis of allergic bronchopulmonary aspergillosis (ABPA) is important. Initiation of corticosteroid therapy in ABPA is essential to prevent progressive destruction of lung parenchyma. The earliest radiographic manifestations of the disease may be present only on bronchograms. In addition to the classic radiographic findings (infiltrate, massive homogeneous consolidation, tram-line shadow, parallel line shadow, ring shadow, toothpaste shadow, glove-finger shadow), perihilar infiltrates simulating adenopathy (pseudohilar adenopathy) and air fluid levels were frequently demonstrated.

The A(z) value for power Doppler imaging compares well with that for mammography, a generally accepted screening examination, and with most other imaging examinations. Power Doppler imaging is likely to be a reasonably accurate and cost-effective screening examination for carotid artery stenosis in asymptomatic populations.

We examined the natural history of simple renal cysts in 59 patients followed periodically with renal ultrasonography. Using the parameters of cyst diameter and number we grouped the patients according to the differing natural history of the cystic lesions. The results indicate that simple cysts tend to progress in number rather than size. Furthermore, 3 patients had independent solid or complex lesions. The only patient explored had an adenocarcinoma of the kidney. Periodic reevaluation of patients with an ultrasonic diagnosis of simple renal cyst warrants serious consideration.
