“…25 Hemangiomas are characterized by vascular channels lined by endothelium, but they are extensively filled with red blood cells instead of the amorphous proteinaceous material of lymphangiomas. D2-40 positivity can assist in highlighting the lymphatic endothelial differentiation; however, attention should be given to the fact that D2-40 can also stain myoepithelial cells of blood vessels.…”

Splenic lymphangioma is a rare malformation of the splenic lymphatic channels, mostly seen in children. It is characterized by the presence of cysts, resulting from increases in the size and number of thin-walled lymphatic vessels that are abnormally interconnected and dilated. The condition may be restricted to the spleen, but in most cases it involves multiple organs (systemic lymphangiomatosis). The clinical picture is variable; small lesions are often incidentally detected through imaging studies, while larger lesions can result in compression of organs, causing pain or rupture even after minor trauma. Therefore, splenic lymphangiomas should be considered in the differential diagnosis of splenomegaly or left upper quadrant pain even among adults and should be immediately treated with splenectomy; delay in the therapeutic intervention can lead to life-threatening complications.

“…Los linfangiomas se producen como parte de una linfangiomatosis quística sistémica o como lesiones solitarias. Los linfangiomas simples, únicos o solitarios constituyen la forma más rara de presentación 2,3,8,9,11,12 . La mayoría de los linfangiomas se presentan en el cuello y axilas (95%), todas las otras localizaciones, incluyendo la intraabdominal son infrecuentes, alcanzando a 5% de todos los casos 4,11 .…”

“…La ecografía abdominal es útil como examen inicial en el diagnóstico de quistes esplénicos; sin embargo, no es útil para delinear la topografía de la lesión 2,3 . La TAC no sólo demuestra la topografía de la lesión, sino su tamaño, naturaleza y relaciones anatómicas [2][3][4][5]12 . La resonancia magné-tica abdominal no presenta mayores ventajas sobre la TAC, a excepción de evitar la exposición del paciente a la radiación 2 .…”

Littoral cell angioma of the spleen: Appearance on sonography and CT

Littoral cell angioma (LCA) is a rare benign vascular tumor of the spleen with characteristic histomorphologic features. Only a few descriptions of the radiologic appearance of this tumor have been published, and those descriptions are variable. We report a case of LCA in a 37-year-old man with psoriasis and nonspecific symptoms of weakness, pain and fatigue, normocytic anemia, and thrombocytopenia. The results of abdominal sonography and contrast-enhanced CT correlated: the 2 modalities revealed hepatosplenomegaly and multiple round splenic lesions of similar appearance and size (on sonograms, ill-defined echogenic lesions up to 3.2 cm without acoustic enhancement; on CT scans, hypodense, nonenhancing lesions up to 3.5 cm). Because making a differential diagnosis was difficult and our presumptive diagnosis was hemangioma or lymphoma, splenectomy was performed. Postoperative pathologic examinations confirmed a final diagnosis of LCA. The patient's recovery was uneventful. LCA should be considered when making a differential diagnosis of splenic lesions, and sonography may be more helpful than CT in reaching a diagnosis of LCA.
