Coronal (a) and axial (b) CT-phlebography of abdominal veins detected compression of the IVC (white arrow) by multicystic heterogeneous masses (red arrow) and stenosis of the suprarenal IVC lumen.. CT, computed tomography; IVC, inferior vena cava.

ALEM, she developed dyspeptic syndrome lasting several days (September 2018). An ultrasound examination of her abdomen and CT-phlebography (Figure 1) showed compression of the inferior vena cava (IVC) with cystic lesions.

Axial abdominal MRI showed on diffusion-weighted image a hyperintense signal of multicystic masses (red arrow) localized around the stenotic IVC lumen (white arrow). Restricted diffusion of multicystic masses represented an acute stage of echinococcosis.. IVC, inferior vena cava; MRI, magnetic resonance imaging.

Additional examinations (ultrasonography of the abdomen, CT scans of the head, chest and abdomen, MRI examination of the abdomen) showed a massive reactivation of echinococcosis in the abdominal area (right retroperineum, the suprarenal part of the IVC) (Figure 2).
Axial abdominal MRI showed on native T1 fat saturated sequence an abnormal hyperintense signal of the IVC lumen (white arrow) that indicated a suspicious thrombosis of the IVC.. IVC, inferior vena cava; MRI, magnetic resonance imaging.

The IVC and common iliac veins bilaterally were nearly completely obturated by hyperintense material on native T1 fat saturated sequence (Figure 3) and after contrast medium administration without an enhancement (Figures 4 and 5), possibly CE, as suggested by the radiologist.
Axial abdominal MRI showed on postcontrast T1 fat saturated sequence a hypointense signal of the IVC lumen (white arrow) that confirmed a thrombosis of the IVC.. IVC, inferior vena cava; MRI, magnetic resonance imaging.

The IVC and common iliac veins bilaterally were nearly completely obturated by hyperintense material on native T1 fat saturated sequence (Figure 3) and after contrast medium administration without an enhancement (Figures 4 and 5), possibly CE, as suggested by the radiologist.
Coronal abdominal MRI showed on postcontrast T1 fat saturated sequence a hypointense signal of the IVC (white arrow), bilateral iliac veins (red arrow) and renal veins (yellow arrow) that confirmed their thrombosis.. IVC, inferior vena cava; MRI, magnetic resonance imaging.
