Fig. 1.
Magnetic resonance imaging (MRI) of littoral cell angioma. Unenhanced T2w image (a) reveals multiple hyperintense lesions in the spleen (A). The lesions are isointense on T1w imaging (B). Due to dyspnoea, the patient did not tolerate additional sequences or contrast agent injection
Fig. 2.
Contrast-enhanced computed tomography (CT) and biopsy. CT scans acquired 80 sec after injection of 80 ml of iodine-based contrast agent (A, B) show disseminated hypodense lesions throughout the spleen, which is not enlarged. (C) CT-guided biopsy with sampling of three tissue specimens with an 18-gauge needle
Fig. 3.
Contrast-enhanced ultrasound (CEUS) of the spleen. Primary CEUS examination after injection of 1.6 ml SonoVue® (Bracco Imaging, Milan, Italy). On B-mode ultrasound, the slightly hyperechogenic target lesion (A) shows no early enhancement (20 sec after injection) and is hypoechogenic in the late phase of the CEUS mode (C)
Fig. 4.
Real-time CEUS-guided biopsy of the target lesion. After identification of a target lesion (white circle), biopsy is performed with a needle guidance system showing the biopsy marker as a green dashed line with an angle of 65°
