Statin induced myopathy is the most commonly seen side effect in users of this family of drugs. Their different forms present with either creatine phosphokinase (CK) elevation or not, signs of in vivo oxidation injury or not or a combination of both. The pathogenetic background, however, still remains obscure. ⋯ No uptake abnormalities in any muscular segment either in the patients or the control group were seen. Thus, MIBI scintigraphy is not useful, apparently, in diagnosing and eventually localizing statin induced myopathy. These findings indicate that MIBI scintigraphy is of no help for diagnosis and gaining further insight into statin induced myopathy.

Swyer-James-MacLeod syndrome (SJMS) is considered to be a relatively uncommon disease presenting with unilateral hyperlucent lung due to hypoplasia of a pulmonary artery and bronchiectasis of the affected lung. In this report, we describe the ventilation-perfusion (V/Q) scan findings of nine male recruits (aged 20-29 years, mean 24.4+/-2.96 years) with SJMS in whom the diagnosis was first established in adulthood. V/Q scan findings of all patients were compared with those on planar radiographs, pulmonary function studies, high resolution computed tomography (HRCT) and digital subtraction angiography (DSA). ⋯ In contrast to other imaging methods, bronchiectasis as an etiological factor was displayed on HRCT. Some pulmonary areas, which were normal on HRCT and planar radiographs, showed air trapping on V/Q scan. Although a V/Q scan was more helpful in determining the extent of the disease and correlates well with conventional imaging methods, HRCT was the most valuable imaging method for the evaluation of aetiology in unilateral hyperlucent lung.
