Determining the cause of splenic lesions is essential to guide appropriate management; the pattern of calcification together with other imaging and clinical findings can aid with differentiation. Most scalp lesions show nonspecific imaging findings, although some possess characteristic features on CT and MRI. On CT, pleomorphic sarcomas are round, hypoattenuating soft-tissue lesions that closely resemble hemangiomas, but show rapid growth.

Heller, Cystic hepatic lesions: a review and an algorithmic approach. With regard to their imaging features, these masses may be further divided into lesions that arise in association with the epidermis or dermis (cutaneous lesions), lesions that arise within the substance of the subcutaneous adipose tissue, or lesions that arise in intimate association with the fascia overlying the muscle. A trichilemmal cyst, also known as a wen, is a common cyst that forms from a hair follicle.

This section revolves around the complexity of calcified coronary lesions and their treatment, from specialised balloon technology to atherectomy devices and lithotripsy. Ultrasound is the imaging method of choice and in many cases a definite diagnosis is possible, especially if the lesion is cystic. The development of a splenic mass represents a dysregulated tumor microenvironment within the spleen as a result of extramedullary hematopoiesis and increased endothelial cell proliferation [55]. The most common malignancy in the spleen is lymphoma, with the spleen being one of the most commonly involved organs; however, it is rarely the only affected organ [1]. Lesions are heterogeneously hypoattenuating with hyperenhancement in areas of necrosis and areas of hemosiderin deposition with calcification on imaging [6, 40, 50, 52] . Abstract.

More than five punctate calcifications in the spleen has been described to be more characteristic of histoplasmosis, whereas less than five calcifications may be reflective of splenic involvement in tuberculosis [31]. High-density thorium dioxide deposits can be seen in the liver, spleen, and lymph nodes on CT. Splenic lesions may also reflect benign systemic abnormalities such as disseminated granulomatous infection or underlying portal venous congestion. Incidental finding of lumps in the scalp. Some cysts may have internal septations that enhance with contrast administration [10].

This section revolves around the complexity of calcified coronary lesions and their treatment, from specialised balloon technology to atherectomy devices and lithotripsy. Splenic hemangiomas are usually small and exhibit slow growth related to nonencapsulated proliferations of blood vessels [5, 9]. 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.
