A rare case of giant cell tumor of the anterior rib presenting as a breast mass.

Initial diagnostic ultrasound of a 22-year-old female patient presenting with a palpable breast mass revealed a suspicious mass initially thought to arise from the breast. However, follow-up diagnostic mammography was normal without evidence of the 5 cm mass seen on ultrasound, and pathology results from ultrasound-guided core needle biopsy raised suspicion for giant cell tumor, making chest wall origin of the mass more likely. Further CT and MRI imaging indeed revealed a locally invasive mass arising from the anterior fifth rib. The patient was treated with denosumab to decrease tumor burden before surgery, and subsequently underwent successful surgical resection of the tumor with mesh overlay and flap reconstruction of the chest wall defect. This case highlights the importance of keeping chest wall lesions in the differential for lesions presenting clinically as breast lesions. Despite the rarity of giant cell tumor of the anterior rib and its unusual presentation as a breast mass, appropriate diagnostic imaging work-up allowed for successful diagnosis and treatment in this case.

Ultrasound evaluation of portal venous gas and its mimics.

Portal venous gas on abdominal ultrasound classically represents an indirect indicator of bowel ischemia, a critical condition which poses a high patient mortality and therefore warrants emergent corrective action. While the classic appearance of portal venous gas on ultrasound is well-described in the literature, the characteristic descriptors are nonspecific and may actually represent other less emergent mimics. Therefore, while radiologists should remain vigilant for the detection of findings corresponding to portal venous gas, they should also be aware of similar-appearing entities in order to provide the most accurate diagnosis. This pictorial essay will open with imaging examples of true portal venous gas attributable to bowel ischemia and describe the classic features which should alert radiologists to this specific diagnosis. Subsequently, this pictorial essay will provide imaging examples of other various other clinical entities which on ultrasound may share similar imaging characteristics. An important objective of this pictorial essay is to highlight distinguishing imaging features along with specific clinical circumstances for each pathological entity which can direct radiologists into identifying the correct diagnosis.

Academic radiology department subspeciality organization & fellowship offerings: A hodgepodge.

INTRODUCTION: As opportunities for radiologists to subspecialize have increased, many avenues to organize Radiology department subspecialties exist. This study seeks to determine how academic U.S. Radiology departments structure themselves with respect to subspecialty divisions/sections, as there are no current standards for how Radiology departments are subdivided. Additionally, the extent of Radiology fellowships offered are assessed. The websites of academic U.S. Radiology departments, a highly influential source of information, were analyzed to perform this study. MATERIALS & METHODS: Radiology department websites of all allopathic U.S. medical schools (n = 148) were assessed for the following: presence/absence of Radiology department subdivisions, division/section labels, number of divisions/sections, division/section titles, presence/absence of Radiology fellowships, number of fellowships, and fellowships titles. RESULTS: 114/148 (77 %) medical schools had Radiology department websites. According to their respective websites, 66/114 (58 %) academic Radiology departments had subspecialty divisions/sections, whereas 48/114 (42 %) had no divisions/sections listed. Of the departments that had divisions/sections, the median number of divisions/sections per department was nine, and ranged from two to 14. Fellowships were offered at 82/114 (72 %) academic Radiology departments that had websites, and the median number was six, ranging from one to 13. CONCLUSION: There is marked heterogeneity of departmental organization across Radiology departments nationwide, likely due to the lack of current standards for how Radiology departments are subdivided into divisions/sections. Of the 77 % of medical schools that have Radiology department websites, only 58 % of departments listed divisions/sections, and 72 % posted fellowship offerings.
