A case of Wolman's disease or primary familial xanthomatosis with calcification of the adrenals is presented. The bilaterally enlarged, calcified adrenals are virtually pathognomonic of this condition.
The pattern of soft tissue calcification in the three cases presented suggests that the debris about a Charcot's joint may break out of the periarticular space and dissect along muscle planes. Follow-up films of one of the cases documents that such calcifications may be resorbed. The reason for selective involvement of certain muscle groups is obscure. To my knowledge, these observations have not been reported previously.
A solitary kidney containing a single calyx and probably a single papilla is described. The embryology of this entity and its similarity to the unipapillary kidney in other mammals are discussed.

Eighty-three intravenous pyelograms were studied to evaluate thinning of the parenchyma on the medial edge of the superior pole of the kidney as an indicator of vesicoureteral reflux. The data indicate that this finding is suggestive of reflux: the greater the difference between the two sides, the more likely the patient is to reflux.

The imaging findings of a crack cocaine "body stuffer" are presented along with findings from in vitro experimentation with crack cocaine. It has been shown previously that contrast enhanced radiographic examinations can often outline the vessel in which ingested cocaine is contained; our work demonstrates that the crack cocaine itself may be visualized with CT performed without intravenous or oral contrast material. Due to the cost of CT, however, it is indicated only when clinically warranted to guide treatment. Positive identification of ingested crack cocaine by CT might prove helpful for both medical and legal indications.
