Background/Objective: It is important to keep the spleen with the help of imaging in today world. We can see VARIATIONS like asplenia, polysplenia (2 -16 pieces) at MRI. Normal spleen has a size up to 1cm and less than that is asplenia or atrophy of spleen. It is common to see large vessels anomalies. We can evaluate it after spleen surgical removal, also spleno-sis, and accessory spleen. The aim of this presentation is to report VARIATIONS of spleen site on CT.
Patients and Methods: All the 3000 cases had sono-graphy report or CT. Some of them had MRI report. All the patients received oral or intravenous contrast media.
Results: Among 3000 CT, there were 240 cases of ac-cessory spleen, two cases of poly spleen, one case of pelvic spleen, 90 cases of spleen metastasis which were mostly lymphoma, 25 cases of Hydatid cyst, three cases of simple cysts, three cases of small spleen (1-6 cm), two cases of huge splenomegaly, 14 cases of spleen calcifications, 15 cases of accessory spleen which in one case it was more than 3.5cm. There were five cases with spleen measured 8 -12 cm in di-ameter which were after splenectomy due to Thalas-semia major and it was as a result of enlargement of accessory spleen which was not diagnosed, also two cases of multi- accessory spleen were found. Other complications of spleen were five cases of abscess and infections, 12 cases of spleen infarction, 36 cases of spleen rupture, two cases of cavernous hemangioma and one case of capillary hemangioma.
Conclusion:1-Sonography had better accuracy in the case of internal texture, tumors and cysts in compari-son with CT. 2-CT had better accuracy than sonogra-phy at calcification, an splenic surroundings, spleen infarction and splenic vessels investigation. 3-CT is mandatory for major thalassemia and the ones who must go under splenectomy. Also CT is necessary for revealing accessory spleen which may be missed at sonography. 4- For finding pelvic spleen CT, CTA and MRI are possible but sonography and doppler are difficult. 5-RN Scan has the minimum role at spleen imaging.
