CT plain and enhanced scan. (A) Hydatid lesion in liver and enlarged lymph node in the hepatogastric space with diameter of 2.13 cm. B (portal vein phase) and C (delayed phase) showed circular enhancement.

The abdominal computed tomography (CT) showed lesion located in S4-5-6 and slightly low-density lymph node existed in the hepatogastric space with diameter of 2.13 cm (the lesion on maximum diameter was not displayed in order to show the lymph node better, Fig. 1.
MRI scan. A (T1), B (T2) Sequence and C (enhanced scan) showed enlarged lymph node in hepatogastric space with slightly longer T2 signal.

The results of magnetic resonance imaging(MRI) scan also considered hepatic alveolar echinococcosis (Fig. 2.
Postoperative microscopic findings. HE staining of lymph node, x10, showed that the central structure of lymph node was basically all hydatid tissue, and a small number of follicles under the capsule

Postoperative pathology confirmed that both primary focus and regional lymph node were alveolar echinococcosis. (Fig. 3).
