Paddling Film Festival, Approximately 5060% of patients with these neoplasms have gain-of-function mutations in the Janus kinase 2 gene (JAK2) [53, 54]. This distinction is made, because lesions greater than 3 cm are usually malignant, while smaller lesions can be either benign or malignant. Lesions are heterogeneously hypoattenuating with hyperenhancement in areas of necrosis and areas of hemosiderin deposition with calcification on imaging [6, 40, 50, 52] . Patients are often children or young adults who typically show no symptoms.

Those that calcify after regression, in cases of histoplasmosis or tuberculosis, may appear as stippled, diffuse calcifications in an otherwise normal spleen [3] (Figs. 18(3): p. 67585; quiz 726. A, Axial contrast-enhanced CT images of abdomen and pelvis show incidental splenic mass (arrow, A) with punctate calcifications and peripheral discontinuous mild enhancement on portal venous phase (A) with progressive fill-in on magnified view of delayed phase (B). Alcohol or a chemical compound may be used as the solution. #1 Rx: IV mannitol (rapid effect)! At this stage, CT may show multiple peripheral wedge-shaped areas of hypoattenuation; however, this ultimately advances to autosplenectomy with little residual functional splenic tissue and diffuse ferrocalcinosis that appears as a small shrunken spleen with coarse confluent calcifications [3, 10, 14, 2024] (Fig. 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. Some lesions may have coarse central calcifications in a radial pattern as a result of underlying fibrosis [52].

Hyperdense Lesions There are a variety of causes for lesions to be hyperdense (hyperattenuating) on CT scanning. Coronary angiography grossly underestimates the presence, extent, severity, and depth of coronary calcification (Figure 1). Malignant scalp tumors are uncommon; however, they carry a potential risk of delayed detection, resulting in poorer outcomes. Acne keloidalis nuchae (AKN), an infrequent but deforming disorder of mostly young males, is a chronic scarring folliculitis expressed as papules and pustules, or plaques and nodules on the nape of the neck [ 10 ].

A meningioma is a tumor that arises from a layer of tissue (the meninges) that covers the brain and spine. ADVERTISEMENT: Supporters see fewer/no ads. Echinococcus eggs invade the gastrointestinal mucosa and colonize in the liver via portal venous transmission, from which they can seed the spleen via peritoneal or hematogenous routes [3, 33, 34]. . There is a high 1-year mortality rate associated with this malignancy [51]. In this case the keratin has calcified. Multifocal lesions in the liver may appear as hypoattenuating lesions with rim enhancement and associated capsular retraction [46]. Appearance of lesion was most consistent with small cavernous hemangioma given its imaging characteristics. Ultrasound is the imaging method of choice and in many cases a definite diagnosis is possible, especially if the lesion is cystic. Multimodality cardiovascular imaging is an essential component of the clinical management of patients with large-vessel vasculitis (LVV), a chronic, relapsing and remitting inflammatory disease of the aorta and its major branches. If present, the calcifications will be thin and curvilinear and along the peripheral wall or along the internal septations [8] (Fig. Epub 2021 Aug 27. Epidermoid cysts are among the rarest type of true cysts and are thought to develop from mesothelial cells entrapped within the spleen during early embryonic development [14, 15]. Epidermoids, containing both cholesterol and keratin, are slow-growing benign cysts and could be diagnosed by computed tomography (CT) or magnetic resonance imaging (MRI) [].Especially, CT scanning, a faster, easier and less expensive imaging method than MRI, has become a regular examination for intracranial, skull and scalp tumors in clinic. 18,19 Advanced intravascular imaging techniques enhance identification of calcium, and permit comprehensive assessment of calcium burden, eccentricity . Ultrasonography usually reveals a well-demarcated lesion, with central punctate hyperechoic images (corresponding to calcification), a thin hypoechoic rim (representing the connective-tissue capsule) and posterior shadowing. Fig. 4.

However, the pathophysiologic features for splenic lesions in myelofibrosis are not well elucidated in the current literature, much less the presence of calcifications in splenic lesions. It should be suspected when a semi-spherical avascular mass with well-defined margins, iso- or hyperechoic in most cases, with thin internal echogenic lines parallel to the long axis of the tumor, is observed between the galea aponeurosis and periosteum of the cranial bone. 2A).
