Ocular siderosis should be considered in the differential diagnosis of a tonic or Adies pupil. To detect an occult intraocular foreign body, clinicians should not rely exclusively on computed tomography scanning or plain film radiography, but should also use B-mode echography with careful study of the inferior quadrants. In ocular siderosis a preoperative electroretinogram reduction in amplitudes of as much as 40% may be reversible after intraocular foreign body removal.

Sprague Dawley rats were divided into two groups. Ten were kept in room air and 10 in hypobaric hypoxia (air at 380 mm Hg). After two weeks all were injected intravenously with 50 muCi of 201Tl and sacrificed. The right and left ventricles were separated, weighed, and measured for radioactivity in a gamma well counter. Left and right ventricular mass ratios (MR) correlated with 201Tl radioactivity ratios (TAR) in both control and hypoxic rats: r = 0.962 where MR = 0.863 TAR + 0.27. Myocardial 201Tl uptake reflects and quantitates normal and abnormal ventricular mass, the abnormal mass in this model consisting of right ventricular hypertrophy associated with hypoxic pulmonary hypertension.

We present the case of a 56-year-old man who presented with rhabdomyolysis and was found to have acute myeloid leukemia (AML). Our case is the first to show an association of rhabdomyolysis with AML. Although rhabdomyolysis is likely a very rare clinical presentation of AML, our case raises awareness for workup for AML in patients who present with rhabdomyolysis and other suspicious findings. Both conditions are medical emergencies and require immediate treatment.
