The prevalence of calcifications ranges from 30 to 40% (by angiography evaluation) but is higher when analyzed by intra coronary imaging. A trichilemmal cyst, also known as pilar tumor, is a common cyst that forms from a hair follicle. Patients are infected by Echinococcus granulosis tapeworm eggs in contaminated food or from contact with dogs in endemic regions such as the Mediterranean and Middle East, South America, Australia, and New Zealand. Whereas most calcified splenic lesions are presumed to be sequel-ae of prior granulomatous infection, there is a broader differential diagnosis for these lesions. Th An algorithmic approach to splenic lesions according to their characteristic calcification patterns can therefore narrow the differential diagnosis and help guide management. When compared with pseudocysts, which are the primary differential diagnostic consideration for these lesions, true epithelial cysts are more likely to have internal enhancing septations but are less likely to have wall calcifications [14].

C, 55-year-old man with known Pneumocystis carinii pneumonia infection at follow-up imaging. Depending on whether the parasite is alive, dead, or degenerating and calcified, hepatic cysticercosis can show varied imaging features. Splenic injury accounts for approximately 50% of organ injuries in blunt abdominal trauma [16]. Among splanchnic artery aneurysms, they are the most common at around 60% [56]. Radiology or tomography shows the lesion and may present peripheral calcifications. They are most often found on the scalp. Type III cysts may be densely calcified with dead scolexes [3, 33, 34].

Axial unenhanced CT image (B) shows more than five diffuse punctate splenic calcifications, which is consistent with earlier treated granulomatous disease. iv. Specifically, imaging procedures allow visualization of vesicular, colloidal, granular-nodular, and calcified phases of neurocysticercosis in the CNS (figure 2). Ovarian mucinous neoplasm in particular may involve psammomatous calcifications that invade the splenic parenchyma. avoid atropine (mydriatic; precipitates glaucoma)! MRI of Focal Splenic Lesions Without and With Dynamic Gadolinium Enhancement, Pattern of the Month. MeSH Neuroimaging is especially useful in the diagnosis of neurocysticercosis since it permits visualization of the parasite stage, as well as the number and localization of lesions 72. Axial contrast-enhanced CT image (D) shows multiple daughter cysts and peripheral thick rim calcifications. Because of osseous or chondroid metaplasia in 16% of cases, these lesions can develop punctate or coarse calcifications [48, 49].

On CT, pleomorphic sarcomas are round, hypoattenuating soft-tissue lesions that closely resemble hemangiomas, but show rapid growth. Radiographics. This distinction is made, because lesions greater than 3 cm are usually malignant, while smaller lesions can be either benign or malignant. Axial contrast-enhanced CT image of abdomen shows low-attenuation mass in spleen with stippled internal calcifications and diffusely increased attenuation of intraperitoneal ascites, consistent with peritoneal carcinomatosis. Solitary or multifocal lesions are less common than miliary or diffuse infiltration, therefore CT and MRI are not sensitive for detecting splenic involvement. CT is sometimes applied in acutely ill patients with infections to assess whether an abscess is present. Angiosarcoma is the most common primary malignant splenic solid tumor, but it is very rare overall. Other granulomatous diseases that can present with hepatic calcification are brucellosis and coccidioidomycosis [2]. Multifocal lesions in the liver may appear as hypoattenuating lesions with rim enhancement and associated capsular retraction [46]. Radiographics, 1998. Epidermoid cysts are managed conservatively.
