Radiologic and pathologic findings. (A) Liver CT scan for the evaluation of liver function test (LFT) abnormality: liver CT scan at the time of admission shows a localized hypoattenuated area in the lateral segment of the liver (arrow; A1). CT scan after discharge shows the improvement of the lesion (arrow; A2: nonenhanced image, A3: enhanced image). (B) Kidney biopsy results: No cellular crescents and no evidence of focal sclerosis of the glomeruli are evident (B1, PAS,×100). Tubules focally reveal oxalate crystal deposits (arrow)(B2, PAS,×200) with necrosis (B3, PAS,×200). The interstitium exhibits focal moderate inflammatory cell infiltrates and fibrosis (B4, H&E,×200). CT, computed tomography; H&E, hematoxylin and eosin; PAS, periodic acid-Schiff.
