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]. 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. Although patients presenting with scalp masses are frequently seen in daily practice, differentiation of scalp lesions is often challenging for radiologists who are not familiar with the imaging of cutaneous lesions. Outdoor Kitchen Cabinets, Please enable it to take advantage of the complete set of features! FOIA Technology And Food Security, They are most often found on the scalp. A, Axial contrast-enhanced CT image with bone window shows large liver mass with coarse internal calcifications and smaller partially calcified lesion in spleen. 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]. 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. OBJECTIVE. It is a malignant vascular tumor that is usually multifocal with metastatic involvement of multiple other visceral organs and connective tissues [46]. Cranial pilomatricoma: a diagnosis to consider. Pathologically, portal hypertension leads to congestive splenomegaly and then internal foci of hemorrhage and necrosis, in which hemosiderin, calcium, and fibrotic tissue accumulate [27, 28].

Trichilemmal cysts, otherwise known as pilar cysts or isthmus-catagen cysts, are the most common form of intradermal or subcutaneous cysts of the scalp, accounting for 5-10% of the population. Imaging may show a solitary mass, multiple splenic masses, or diffuse splenic involvement with splenomegaly. 9 Although patients presenting with scalp masses are frequently seen in daily practice, differentiation of scalp lesions is often challenging for radiologists who are not familiar with the imaging of cutaneous lesions. However, calcifications are much less common in these cysts than in pseudocysts [16]. The main consideration for differential diagnosis is a hemangioma, which is best ruled out in favor of angiosarcoma with evidence of metastatic disease [52]. and there are often recurrent episodes of thrombophlebitis in or around the lesions. Bookshelf AJR Am J Roentgenol. A trichilemmal cyst, also known as a wen, is a common cyst that forms from a hair follicle. Fig. Gamna-Gandy bodies are best visualized on CT when calcified; they appear as areas of hyperattenuation on unenhanced imaging.

With color flow Doppler imaging, 10 of the 11 injuries were identified, for a sensitivity of 91% and a specificity of 98.6%. On T2-weighted MR images, regenerative nodules typically appear hypointense, whereas HCC classically appears moderately hyperintense [4]. Color Doppler did not evidence any flow within the lesion. Coronal T2-weighted MR image (E) shows internal increased signal intensity, which is consistent with fluid-filled daughter cysts, and loss of peripheral rim signal intensity, which is consistent with coarse calcifications and blooming artifact. Palpable lesions of the scalp and face are common in clinical practice. Careers. Radiologists must be familiar with the appearances of common scalp lesions to reach an accurate diagnosis.
