Oxaliplatin is a platinum-based antineoplastic agent used in cancer chemotherapy. Oxaliplatin-induced hepatic sinusoidal obstruction syndrome (HSOS) has been reported in the context of chemotherapy for liver metastasis of colorectal cancer. However, to the best of our knowledge, there is no report of oxaliplatin-associated HSOS in patients with gastric cancer. The present study reported a patient with gastric cancer who received proximal gastrectomy and oxaliplatin-containing chemotherapy. Contrast-enhanced computed tomography revealed that liver parenchyma appeared heterogeneous and demonstrated hypoattenuation in the portal phase. In dynamic contrast-enhanced magnetic resonance imaging, hypointense heterogeneity was demonstrated in the portal-venous phase. Pathological examination indicated distinctive multifocal sinusoidal dilatation. In conclusion, the present report indicated a case of oxaliplatin-induced HSOS in a patient with gastric cancer who received oxaliplatin-contained chemotherapy.
