The solution causes scarring and helps prevent the cyst from filling with fluid again. In the bones, epithelioid hemangioendothelioma presents as mixed sclerotic-lytic lesions, whereas in the visceral organs it grows as coalescing, often calcified masses and then metastasizes to involve other organs [29, 46].

Also, the cavernous sinus wall can be depicted Calcification is seen in the vast majority (~90%) of these more consistently. In general, splenic lesions are managed conservatively even when the patient is showing symptoms of disease. Patients may need partial or total splenectomy for management because of the high rate of recurrence with percutaneous drainage, especially if the cause is trauma [17, 18]. Splenic hemangiomas are the most common benign primary neoplasm in the spleen, and can be of cavernous or capillary subtype [4].
