Chemotherapy is required because of the high proportion of cases with metastatic disease, and splenectomy is also required due to the high risk of rupture [50]. Associated findings with ovarian cancer or other metastatic cancers may include malignant ascites, peritoneal carcinomatosis, and omental cake [38] (Fig. B, 64-year-old woman who presented with hepatic angiosarcoma and prior exposure to thorium dioxide (Thorotrast). Complete splenectomy is avoided because of the resultant increased risk of infections in younger patients [7]. The calcifications within hemangiomas can appear as central punctate, curvilinear, or speckled in areas of thrombosis [6, 9, 10]. The use of 18F-FDG PET imaging to evaluate plaque vulnerability and the risk of associated ischemia episodes has been supported by some evidence from other research [ 166 ]. Radiology 2007;242:388-395. Approximately 5060% of patients with these neoplasms have gain-of-function mutations in the Janus kinase 2 gene (JAK2) [53, 54].

The liver may show reticular and lacelike calcifications with surrounding hyperattenuating, hemorrhagic as-cites [36, 37]. 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]. Appearance of lesion was most consistent with small cavernous hemangioma given its imaging characteristics. Two patients with myelofibrosis at MD Anderson Cancer Center had hypoattenuating solitary splenic masses with coarse internal calcifications with concurrent splenomegaly, with no other cases of splenic masses in myelofibrosis described in the literature (Fig. 8). 2010 Jan;56(1):133-47 Fig. Angiography is the diagnostic method reference standard; however, it is invasive [58].

Assessment of combination of contrast-enhanced magnetic resonance imaging and positron emission tomography/computed tomography for evaluation of ovarian masses. On T2-weighted MR images, regenerative nodules typically appear hypointense, whereas HCC classically appears moderately hyperintense [4]. Non-Hodgkin lymphoma, particularly diffuse B-cell lymphoma, is the most common subtype of lymphoma in the spleen, with 3040% of patients with non-Hodgkin lymphoma having splenic involvement, especially those who are at least 60 years old [12, 41, 42]. Later, in the degenerative stage, multiple millet-shaped elliptic calcified cysts have an appearance like a starry night on CT [3]. Hemangiomas are benign vascular neoplasms which grow by endothelial cell hyperplasia. Ex cluded from the study were lesions with no identifiable soft tissue component such as osteomas, "ground glass" fi broosseous lesions, and purely radiodense lesions such as some odontomas. Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. 8, No. High-density thorium dioxide deposits can be seen in the liver, spleen, and lymph nodes on CT.
