Although peritoneal carcinomatosis is the most common entity involving the peritoneum diffusely, a vast array of unusual diseases may affect the peritoneal surfaces. These entities can be further categorized into infectious, neoplastic, and miscellaneous conditions. Cross-sectional imaging, including computed tomography and magnetic resonance imaging are excellent modalities for further characterization of these unusual diseases. For some of these conditions, imaging-specific diagnosis is achievable. For others, the diagnosis can be favored when clinical and/or cross-sectional imaging features coexist.

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.

The authors presented the computed tomography and magnetic resonance imaging appearances of a painful os cuboideum secundarium. To the authors' knowledge, this is the first report of the cross-sectional imaging appearance of this condition, and serves to underline the utility of computed tomography and magnetic resonance imaging in the investigation of foot pain.

Despite progress in noninvasive imaging with computed tomography and magnetic resonance imaging, conventional angiography still contributes to the diagnostic workup of oncologic and other diseases. Arteriography can reveal tumors not evident on cross-sectional imaging, in addition to defining aberrant or unexpected arterial supply to targeted lesions. This additional and potentially unanticipated information can alter management decisions during interventional procedures.

Introduction Nasopharyngeal carcinoma is a rare neoplasm in the UK. The current gold standard for detection is endoscopic examination under anaesthesia of the nasopharynx with biopsy. Many clinicians are now advocating cross-sectional imaging as the primary investigation. The objective of this study is to evaluate the role of cross-sectional imaging in detecting nasopharyngeal carcinoma and ultimately to avoid unnecessary biopsy. Material and methods This is a retrospective uncontrolled case series review of patients who were investigated for suspected nasopharyngeal carcinoma between 2009 and 2017 at York Teaching Hospital NHS Foundation Trust. At present, any suspected nasopharyngeal carcinoma requires biopsy. Search terms used were ‘endoscopic biopsy of nasopharynx’, ‘endoscopic examination + biopsy nasopharynx’. The main outcome measures are reported histological and radiological features of malignancy. Only patients who had imaging prior to the biopsy were included. Results A total of 144 patients had endoscopic examination under anaesthesia of the nasopharynx with biopsy. Approximately one-third of these patients had cross-sectional imaging before the biopsy. The study revealed that magnetic resonance imaging had 100% sensitivity and 84% specificity; however, the endoscopic examination under anaesthesia and biopsy had only 88% sensitivity. This is due to a negative histological finding despite radiological characteristics of nasopharyngeal carcinoma in some patients. However, the specificity was 100%. Conclusion The study supports magnetic resonance imaging as the primary investigation in patients with suspected nasopharyngeal carcinoma followed by endoscopic examination under anaesthesia and biopsy in cases with suspicious findings on imaging only.

The detection of vaginal lesions has increased with the expanding use of cross-sectional imaging. Magnetic resonance imaging (MRI)—with its high-contrast resolution and multiplanar capabilities—is often useful for characterizing vaginal masses. Vaginal masses can be classified as congenital, inflammatory, cystic (benign), and neoplastic (benign or malignant) in etiology. Recognition of the typical MR imaging features of such lesions is important because it often determines the treatment approach and may obviate surgery. Finally, vaginal MR imaging can be used to evaluate post-treatment changes related to previous surgery and radiation therapy. In this article, we will review pertinent vaginal anatomy, vaginal and pelvic MRI technique, and the MRI features of a variety of vaginal lesions with pathological correlation.

This article focuses on the cross-sectional imaging spectrum of abnormalities that affect the abdominal wall, with emphasis on magnetic resonance imaging (MRI). Cross-sectional imaging is valuable for diagnosing and evaluating the extent of abdominal-wall masses. With the increasing use of MRI, it is often possible to reach a diagnosis or narrow the differential diagnosis, thereby guiding effective management. Neoplastic and non-neoplastic pathologies will be illustrated, and the distinctive imaging characteristics of these entities will be highlighted.

ABSTRACT Cross-sectional imaging is an indispensable tool in the investigation of parapharyngeal space and infratemporal fossa pathologies. Computed tomography and magnetic resonance imaging exquisitely display the complex anatomy of this region and provides accurate spatial localization of pathology, differential diagnosis and vital information for treatment planning.
