Ultrasonography of splenic abnormalities

Figure 1 There is a homogenous, round contour near the hilum, identified as an accessory spleen (AS) in a 62-year-old female. One anechoic cyst is noted within the accessory spleen. The pathologic process affecting the spleen (small cyst) also affects the accessory spleen (large cyst).

Figure 2 Multiple tiny calcified spots involving almost the entire spleen are found in a 58-year-old female with liver cirrhosis, called Gamna-Gandy bodies.

Figure 3 A pseudocyst cyst of the spleen after trauma reveals debris or echogenic contents within the thick wall (arrows) in a 60-year-old female.

Figure 4 Pancreatic pseudocyst eroding into the adjacent spleen and mimicking a huge splenic simple cyst was noted after an episode of acute alcoholic pancreatitis in a 32-year-old male patient.

Figure 5 An atypical hemangioma can have mixed echogenicity with a dominant cystic portion. Mild through transmission points to the cystic nature of the hemangioma.

Figure 6 Large and multiple hemangiomas occupy the entire spleen. The hypoechoic areas shown in Figure 5 are filled with blood clots and thrombosis. The 48-year-old male received splenectomy due to LUQ pain caused by venous thrombosis in spleen.

Figure 7 An enlarged spleen (A) demonstrates a diffusely coarse echotexture with several mixed echoic lesions (B) in a 58-year-old male patient.

Figure 8 Splenic metastasis from a lung carcinoma in a 68-year-old male is seen as a hypoechoic mass with a target sign.

Figure 9 A peripheral wedge-shaped hypoechoic region (arrows) was noted at the upper pole of spleen from an infarction after transcatheter arterial embolization in a 45-year-old male with hepatoma.

Figure 10 A subcapsular crescent-shaped hypoechoic lesion is noted at the upper pole of spleen.

Figure 11 Several linear hypoechoic foci and a subcapsular fluid accumulation are noted in a spleen. Loss of the normal architecture was seen after a traffic accident in a 38-year-old male.

Figure 12 A splenic laceration and rupture (in Figure 11) is identified as a blood-filled cleft (lower arrow) and capsular rupture (upper arrow) on contrast CT.
