| Popis: | The one-hump dromedary camel (Fig. 1) (distinguished from its two-hump Bactrian cousin) provides a descriptive metaphor for a focal contour bulge of the lateral, interpolar aspect of the left kidney. The ‘‘dromedary hump’’—caused by molding of the normal renal parenchyma by the adjacent spleen [1, 2]—was originally described at excretory urography (Fig. 2), but also can be seen with ultrasound, (Fig. 3), CT, and MR. A common anatomic variant, the dromedary hump should be recognized as a pseudomass, obviating the need for additional unnecessary testing [3]. The ‘‘hump’’ should demonstrate the same imaging characteristics as contiguous normal renal parenchyma, regardless of the imaging modality employed. |
