Computed tomography has been used to provide cross-sectional images of fetal specimens. This technique allows us to gain information on anatomic malformations and in general is a useful tool for research and teaching.
The clinical and radiologic diagnosis of exogenous lipoid pneumonitis often goes unrecognized. A specific history of lipoid aspiration is rarely obtained unless specifically sought. We analysed the clinical, radiologic and pathologic findings in 11 patients with pathologically-proven exogenous lipoid pneumonitis. Lipid aspiration results in a predictable pathologic and consequently radiologic pattern of disease, often simulating bronchogenic carcinoma. Transthoracic percutaneous fine-needle aspiration biopsy is useful as a complementary procedure to bronchoscopy in making the diagnosis.
Diagnostic imaging techniques have an important role in supplementing the clinical evaluation of the diabetic. These are discussed in relation to the pathophysiologic changes: vascular degeneration, neurologic and infective changes, and maternal-fetal influences during pregnancy.
A selective intubation method for examination of the afferent loop is described and brief review of complications involving the afferent loop is outlined. The value of the intubation method in patient management is illustrated by three case reports. We find this a helpful method for studying selected patients with clinical problems related to the afferent loop.
Pulmonary aspergillosis is being diagnosed with increasing frequency, particularly in larger referral centers. The spectrum of lung pathology can be classified into 3 major groups: A) non-invasive mycetoma; B) allergic bronchopulmonary aspergillosis and C) invasive aspergillosis. Five patients with pulmonary aspergillosis are presented, illustrating unusual features of each major group. Transthoracic needle aspiration biopsy was diagnostic in 3 patients. It is important to differentiate a mycetoma developing in a pre-existing cavity from a cavitating Aspergillus abscess. The radiologic appearances may be similar, but evolution of the 2 lesions is entirely different.
