Exposure to thorium dioxide (Thorotrast) is the most common iatrogenic cause of hepatic angiosarcoma and it can also cause splenic angiosarcoma. Splenic hemangiomas are usually small and exhibit slow growth related to nonencapsulated proliferations of blood vessels [5, 9]. The purpose of this article is to review calcified or ossified benign soft tissue lesions that may simulate malignancy. Fig. Coronal unenhanced CT image shows calcified left hilar nodes (long arrows, A) and bilateral pulmonary nodules (short arrows, A) with peribronchial interstitial disease, which is consistent with resolving histoplasmosis. Fig. show answer. These lesions are usually asymptomatic but may manifest as a lump with or without associated pain. Granulomatous infections may present with disseminated disease, including calcified lesions in the liver, lymph nodes, and kidneys, both before and after antimicrobial treatment [10, 12, 29, 30]. Extras-plenic findings may include hepatic epithelioid hemangioendothelioma with characteristic capsular retraction [6, 40]. Thorotrast is a highly radioactive contrast agent used until the 1950s [36]. The solution causes scarring and helps prevent the cyst from filling with fluid again. 8 40-year-old man with primary splenic angiosarcoma presented with polycythemia vera. Meta-static melanoma may present as a cystic lesion [12]. On CT, these hydatid cysts are typically well-marginated with internal fluid attenuation and occasional air-fluid levels [14, 33]. {"url":"/signup-modal-props.json?lang=us\u0026email="}, O'Donnell C, Multiple scalp trichilemmal cysts (wens). Radiologists must be familiar with the appearances of common scalp lesions to reach an accurate diagnosis. Type II cysts have internal septa, slightly higher internal attenuation resulting from dense debris, and small peripheral wheellike daughter cysts that often have lower internal attenuation than the mother cyst [14, 16, 32, 34]. 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]. Depending on whether the parasite is alive, dead, or degenerating and calcified, hepatic cysticercosis can show varied imaging features. Additionally, the researchers discovered that symptomatic carotid lesion uptake of 18F-FDG was 27% higher than ipsilateral asymptomatic lesions . Most scalp lesions show nonspecific imaging findings, although some possess characteristic features on CT and MRI. We review the clinical presentations, locations, imaging characteristics, and differential diagnostic considerations of myositis ossificans, tophaceous gout, benign vascular lesions, calcific tendinopathy with osseous involvement, periosteal chondroma, primary synovial . Lymphoma infiltrates the splenic white pulp to a greater extent than the red pulp, forming large nodular masses that typically measure greater than 3 cm in diameter [44]. Additional findings may include hepatic or bone metastatic lesions and splenic rupture in 30% of patients [12, 51]. This rare and interesting case demonstrates epiglottic cartilage calcification with no known underlying cause. A lesion greater than 3 cm in diameter is called a mass. 1. 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. It is more common in young adults, and splenic epithelioid hemangioendothelioma can present as a left upper quadrant abdominal mass or pain [6, 9]. Orbital mycosis is a condition characterized by opportunistic infections, fungal in origin, that has the capacity to be potentially life threatening. In all cases, the granulomas are preceded by multiple splenic microabscesses that are hypoattenuating lesions less than 2 cm in diameter. A, Axial unenhanced CT image shows multiple punctate calcifications within spleen (arrow). Lesions are heterogeneously hypoattenuating with hyperenhancement in areas of necrosis and areas of hemosiderin deposition with calcification on imaging [6, 40, 50, 52] . Early surgical intervention with splenectomy is preferred to reduce the mortality associated with complications or from the subsequent splenic infarction [19]. The https:// ensures that you are connecting to the They may also become calcified. Posted on October 29, 2022 by testicular cancer foods avoid Makhija D, Sisodiya N, Shah H, Waghmare M.

Radiologists may also occasionally encounter benign neoplasms of the scalp, including melanocytic nevi, keratoacanthoma, pilomatricoma, neurofibroma, and lipoma. This may explain an underlying mechanism for splenic masses in patients with myelofibrosis. A calcified or ossified mass in this location is exceedingly rare, but a calcified variant of pleomorphic adenoma has been reported. Some lesions may have coarse central calcifications in a radial pattern as a result of underlying fibrosis [ 52 ]. A risk factor for many of these infections is HIV infection. . Lesions are subcutaneous, with a well-defined, sharp margin ( 13, 14 ). The imaging appearance of a metastatic lesion in the spleen varies with the type of primary cancer [38, 39]. Solitary lesions are usually hypo- or isoattenuating with areas of necrosis and rarely have calcifications [41, 44].

Calcified splenic granulomas are a common incidental finding, most commonly resulting from tuberculosis or histoplasmosis and less commonly from Pneumocystis carinii pneumonia or brucellosis [29, 30]. Calcified lesions are very frequent among coronary artery disease stenotic lesions. Indesign Section Marker, References: O. K. Nakamura; Imaging Department, Sao Paulo, BRAZIL . Solitary or multifocal lesions are less common than miliary or diffuse infiltration, therefore CT and MRI are not sensitive for detecting splenic involvement. B, 75-year-old woman with known myelofibrosis and massive splenomegaly. Patients are often children or young adults who typically show no symptoms. Paddling Film Festival, MRI of Spinal Bone Marrow: Part 2, T1-Weighted Imaging-Based Differential Diagnosis, Structured Review. Axial unenhanced CT image (B) shows more than five diffuse punctate splenic calcifications, which is consistent with earlier treated granulomatous disease. An understanding of the scalp's anatomy is essential for topographic characterization of a lesion as the first step for a differential diagnosis; not only the imaging appearance, but also the lesion's location, the clinical history, and the patient's age should be considered when evaluating a mass of the scalp. Before Ultrasound is the imaging method of choice and in many cases a definite diagnosis is possible, especially if the lesion is cystic. B, Axial unenhanced CT image shows peripherally calcified hypoattenuating mass in splenic hilum with adjacent thick tram-track calcifications of tortuous splenic artery. 7B 58-year-old woman with pathologic pelvic fractures resulting from biopsy-proven metastatic epithelioid hemangioendothelioma.
