2017 Sep;116(3):337-343 Ultrasound is the imaging method of choice and in many cases a definite diagnosis is possible, especially if the lesion is cystic. Axial contrast-enhanced CT image shows peripherally calcified hypoenhancing lesions in liver, multiple calcified intraabdominal lymph nodes, and shrunken calcified spleen. Most scalp lesions show nonspecific imaging findings, although some possess characteristic features on CT and MRI. It most often affects the skin and central nervous system.

Similar to acne conglobata and hidradenitis suppurativa, it is thought to result from episodes of follicular occlusion. Hyperdense Lesions There are a variety of causes for lesions to be hyperdense (hyperattenuating) on CT scanning.

The cartilaginous matrix can only be recognised in conventional radiology and the CT-scan by the presence of calcifications. 4). Trichilemmal cysts may run in families. Incidental splenic calcifications have a broad differential diagnosis; however, they can be readily categorized into a clinically useful shortened list according to the imaging patterns and clinical context. .

Abstract.

Dx: tonometry (increased IOP) o gonioscopy is gold standard! On CT, aneurysms are well-defined enhancing lesions that can have mural thrombus and peripheral calcifications [58]. We collected 235 cases, summarized in Table 1. Applying a pattern recognition approach to calcified liver lesions results in a long list of differential diagnoses, as illustrated by Patnana et al.

FOIA Based on a presentation at the ARRS 2019 Annual Meeting, Honolulu, HI. An understanding of the scalps 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 lesions location, the clinical history, and the patients age should be considered when evaluating a mass of the scalp. Those that calcify after regression, in cases of histoplasmosis or tuberculosis, may appear as stippled, diffuse calcifications in an otherwise normal spleen [3] (Figs. A, Axial unenhanced CT image shows multiple punctate calcifications within spleen (arrow). The main consideration for differential diagnosis of these lesions is a malignant lesion with mixed solid and cystic components that presents with inhomogeneous enhancement and central nonenhancement because of necrosis [5, 6, 9]. Shoulder dystocia is a birth injury that happens when one or both of a baby's shoulders get stuck inside the mother's pelvis during labor and birth. Subgaleal lipoma is a benign tumor of adipose tissue. heart valves. 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.

Splenic hemangiomas are usually small and exhibit slow growth related to nonencapsulated proliferations of blood vessels [5, 9]. 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. This may explain an underlying mechanism for splenic masses in patients with myelofibrosis.

Additional treatment is best determined after diagnosing the underlying abnormality.

Incidental splenic lesions such as are found on CT images of the abdomen are often presumed benign and therefore ignored or are sometimes mischaracterized.

The management strategy for this aggressive splenic malignancy includes surgical removal and chemotherapy [48]. Up to 20% of patients may present with left upper quadrant discomfort symptoms, but otherwise report no symptoms [57]. Appearance of lesion was most consistent with small cavernous hemangioma given its imaging characteristics. Calcified lesions are very frequent among coronary artery disease stenotic lesions. Malignant scalp tumors are uncommon; however, they carry a potential risk of delayed detection, resulting in poorer outcomes. CT Findings of Acute Cholecystitis and Its Complications. 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]. Calcifications can be seen in a vast spectrum of common and uncommon diseases, from benign to malignant, including cystic lesions, solid neoplastic masses, and inflammatory focal lesions.

A wide variety of superficial soft-tissue masses may be seen in clinical practice, but a systematic approach can help achieve a definitive diagnosis or limit a differential diagnosis. Coronal reconstruction of axial CT image (B) shows splenic calcified lesion. Ancillary findings in some diseases can include calcified lymphadenopathy, septal thickening, and pleural calcification. They are usually small and benign, and the lesions tend to be treated simply according to the clinical symptoms.

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].

Pseudocysts, or false cysts [3], make up 80% of all splenic cystic lesions [10]. Nodules and masses can have a wide range of sizes, from tiny nodules <1 mm to masses >10 .

Axial unenhanced CT image shows round anterosuperior splenic lesion with multiple internal coarse calcifications.

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. Axial unenhanced CT image (A) in bone window shows hypoattenuating lesion in anterosuperior spleen with coarse calcifications. In early sickle cell disease, abnormal polymerized hemoglobin leads to perfusion-reperfusion injury and resultant slow microcirculation with splenic sequestration [22].

A trichilemmal cyst, also known as a wen, is a common cyst that forms from a hair follicle. Calcifications can be seen in a vast spectrum of common and uncommon diseases, from benign to malignant, including cystic lesions, solid neoplastic masses, and inflammatory focal lesions. B, Axial unenhanced CT image shows peripherally calcified hypoattenuating mass in splenic hilum with adjacent thick tram-track calcifications of tortuous splenic artery. They are most often found on the scalp.

Gamna-Gandy bodies are asymptomatic nodules that affect 912% of patients with portal hypertension and that occur as a result of the deposition of hemosiderin [3, 16]. Radiographics, 2013. With color flow Doppler imaging, 10 of the 11 injuries were identified, for a sensitivity of 91% and a specificity of 98.6%.

It is a malignant vascular tumor that is usually multifocal with metastatic involvement of multiple other visceral organs and connective tissues [46].

Solitary lesions are most commonly from primary colorectal or ovarian neoplasm [40].

Color Doppler did not evidence any flow within the lesion.
