Abstract
A 59-year-old man was referred for CT scan of the abdomen after repair of an eventrated appendectomy wound. The man had a known history of bipolar affective disorder, for which he had been on lithium therapy for many years. As an incidental finding, CT scan showed numerous small hypodense renal lesions. Subsequently a MRI examination was performed to further characterize these renal abnormalities.

LITHIUM-INDUCED NEPHROPATHY — DESBUQUOIT et al Contrast-enhanced CT scan of the abdomen, reformatted image in the coronal plane (Fig. 1) shows normal sized kidneys with numerous small (1-2 mm) hypodense lesions revealed as adventitious finding
The radiological findings combined with the history of lithium intake for bipolar affective disorder are pathognomonic for lithium-induced nephro pathy
Summary
A 59-year-old man was referred for CT scan of the abdomen after repair of an eventrated appendectomy wound. LITHIUM-INDUCED NEPHROPATHY — DESBUQUOIT et al Contrast-enhanced CT scan of the abdomen, reformatted image in the coronal plane (Fig. 1) shows normal sized kidneys with numerous small (1-2 mm) hypodense lesions revealed as adventitious finding. MRI of the kidneys (Fig. 2) included a T2-weighted image in the coronal plane (A) and an image in the axial plane (B). T2-weighted images show numerous millimetric lesions, with a homogeneous high signal intensity (SI).
