Benign non-cystic scrotal tumors and pseudotumors

There is a wide spectrum of benign, non-cystic scrotal lesions that show characteristic histo-morphology and natural history. While sonography is the preferred modality for the diagnosis of both testicular and extratesticular masses, MRI is used as a problem-solving modality when sonographic findings are inconclusive. This article reviews the cross-sectional imaging features of benign, non-cystic, intra- and extratesticular lesions. Definitive diagnosis of benign scrotal lesions may lead to conservative management including testicular preserving surgery.

Histologic Subtypes

Small bowel malignancies are rare neoplasms, usually inaccessible to conventional endoscopy but detectable in many cases by cross-sectional imaging. Modern multidetector computed tomographies permit accurate diagnosis, complete pretreatment staging, and follow-up of these lesions. In this review, we describe the cross-sectional imaging features of the most frequent histologic subtypes of the small bowel malignancies.

General Appearance

The general appearance of peritoneal carcinomatosis at abdominal CT and other cross-sectional imaging modalities consists of varying amounts of peritoneal-based soft tissue implants (mass-forming or infiltrative), peritoneal fluid, and occasionally calcification. However, a wide variety of common and uncommon neoplastic and non-neoplastic conditions can closely mimic peritoneal carcinomatosis at imaging. Neoplastic mimics of peritoneal carcinomatosis include primary peritoneal and sub peritoneal tumors, as well as peritoneal lymphomatosis and sarcomatosis. Broad categories of non-neoplastic mimics of peritoneal carcinomatosis include tumor-like conditions, systemic processes, atypical infections, and fat-based conditions. For many entities, suggestive or specific patient information and/or CT imaging findings exist that may allow the radiologist to narrow the differential diagnosis. In this article, we review the salient clinical and cross-sectional imaging features of non-neoplastic mimics of peritoneal carcinomatosis and malignancy, with emphasis on the CT findings and the additional clues that may suggest the correct benign diagnosis.

This case reports on secondary extramedullary multiple myeloma within both breasts in the absence of axillary nodal involvement and discusses the difficulty in interpretation with clinical recommendations and learning outcomes. Differentiating plasmacytic lesions in the breast is often difficult as clinical and radiological appearances are known to mimic benignity and high-grade primary breast cancer. Extramedullary presentation can determine progression of the disease and can necessitate cross-sectional imaging. Therefore definitive diagnosis is essential as the clinical management of the patient may be altered.
