The MSCT Imaging Features of the Red Pulp Type Splenic Hamartoma

Objective: To investigate the MSCT imaging features of the red pulp type splenic hamartoma. Methods: Retrospective analysis of the clinical and CT imaging data of 13 cases of red pulp type SH confirmed by operation and pathology, All patients underwent 64 slice spiral CT plain scanning and enhanced scanning. Results: 13 cases were solitary, a total of 13 lesions, diameter of 4.6~10.5 cm, the plain CT scan showed is density in 9 cases, the state is not clear, showed slightly low density lesion in 4 cases, the realm of clear, all cases without fat component and calcification, cystic necrosis, rare, enhanced scan showed 9 patients with lesions density showed diffuse irregular, inhomogeneous patchy enhancement, scan showed slightly low density lesions of 4 cases showed diffuse irregular, uneven patches enhanced obviously, time delay lesions showed homogeneous enhancement in delayed phase of progressive, lesion density close to or equal to the surrounding normal splenic parenchymal density, which was misdiagnosed as malignant tumor of splenic hemangiomas, 1 cases in each. Conclusion: SH is different from the other organs of the hamartoma, has its own characteristics, intralesional often no fat component and calcification, when found in the spleen of solitary mass, enhanced lesions showed diffuse irregular, inhomogeneous enhancement patch or plaque, with the delay time is progressive uniform enhancement, should first consider splenic hamartoma, and more for the red pulp type.
