Multifocal micronodular pneumocyte hyperplasia: computed tomographic appearance and follow-up in tuberous sclerosis complex.
To characterize pulmonary nodules in patients with tuberous sclerosis complex (TSC) using computed tomography. ⋯ Most men and women with TSC have multiple pulmonary nodules, which likely represent multifocal micronodular pneumocyte hyperplasia in the absence of known predisposing factors.

Dynamic computed tomographic pulmonary angiography as a problem-solving tool in indeterminate computed tomographic angiography for pulmonary embolism.
Computed tomographic pulmonary angiography may be indeterminate in regions of slow arterial flow because of underlying lung disease. In this case, dynamic computed tomographic angiography of the pulmonary vasculature (dynamic CTPA) was used to confirm flow variation within the pulmonary arteries in regions of pulmonary fibrosis and excluded pulmonary embolism. ⋯ Dynamic CTPA successfully demonstrates flow variation within the pulmonary arteries and may be a useful adjunct to exclude pulmonary embolism in CTPA cases with questionable arterial filling defects.
