Non mass-like enhancement categories detected by breast MRI and histological findings.

OBJECTIVE: To correlate the different non masslike enhancement categories detected by Magnetic Resonance Imaging (MRI) and the corresponding histological findings. PATIENTS AND METHODS: Two experienced radiologists reviewed the MRI examinations of 94 patients presenting non mass-like enhancements who had performed histological evaluation. According to the BI-RADS (Breast Imaging Reporting and Data System) lexicon, non masslike enhancements were classified as focal, linear, segmental, regional, ductal and diffuse enhancements. We focused on segmental, regional and ductal patterns. RESULTS: Among the 94 patients, 52.1% showed a regional pattern, 27.7% a segmental pattern and 20.2% a ductal pattern of enhancement. Of the 49 patients showing a regional pattern, the histological diagnosis was ductal invasive carcinoma (DIC) in 28 cases, ductal carcinoma in situ (DCIS) in 4 cases, lobular invasive carcinoma (LIC) in 3 cases and a benign disease in 9 cases. Of the 26 patients showing a segmental pattern, the histological outcome was DIC in 10 cases, DCIS in 7 cases and a benign disease in 5 cases. Among the 19 patients showing a ductal pattern, the result was DIC in 4 cases, DCIS in 4 cases and a benign disease in 7 cases. In most cases DIC presented as a regional pattern, while DCIS showed a segmental pattern in 26.9%, a ductal pattern in 21.1% and a regional pattern in 8.2% of cases. CONCLUSIONS: Our findings about ductal and segmental enhancements agree with the literature. We found a high rate of DIC presenting as a regional enhancement, instead; thus, we recommend a more detailed diagnosis, especially when an homogeneous/heterogeneous and clumped internal enhancement pattern is present.

[Teleradiology: case series and experience acquired in the military field]. / La teleradiologia: casistica ed esperienza acquisita in ambito militare.

PURPOSE: Our aim was to evaluate the peculiarities of military teleradiology on the basis of the large case series collected between January 2006 and December 2010. MATERIALS AND METHODS: We analysed all radiological teleconsultations/telediagnoses requested by theatres of operations: Kosovo, Iraq, Chad, warships Etna (Indian Ocean) and Cavour (earthquake in Haiti), for a total of 1,132 cases. As part of the case series collected in Kosovo (n=827), we evaluated the entire sample of patients transferred to the Celio Military Hospital in Rome following a teleradiological diagnosis (27 examinations analysed). RESULTS: A total of 1,132 radiological examinations were requested (704 military and 428 civilians). Comparison between teleradiology diagnoses and diagnoses made after patient transfer showed almost perfect concordance based on Cohen's Kappa (κ) statistic (92.59% identical diagnoses), with only a small minority of false positive results (two cases, 7.4%). CONCLUSIONS: The use of teleradiology by the Military Medical Corps helped attain an accurate diagnosis in almost all cases, significantly reducing diagnostic errors and limiting transfers from theatres of operation to cases genuinely necessitating transfer.

Skin thickening as unique pathologic sign of an inflammatory breast cancer: a case report and review of the literature.

We report the case of a 42-year-old woman with inflammatory cancer of the right breast treated with neoadjuvant chemotherapy, surgery, additional chemotherapy, and consolidative radiotherapy (RT), that has metastatized to the chest wall and presented a resumption of disease on the contralateral breast. Magnetic Resonance (MR), performed after the second phase's fourth round of additional chemotherapy, showed a modest reduction of scar metastases on the right and a contralateral anomalous skin thickening with high signal intensity in T2 weighted images (WI) with multiple mass-like enhancements located in a wide area of the central region at the union of higher quadrants. These findings were suggestive for resumption of contralateral disease; the biopsy confirmed an inflammatory breast cancer (IBC) infiltrating lobular type with high mitotic rate. A retrospective evaluation of the previous MR exam, performed 5 months before, was conducted: on the left side only a modest skin thickening was found as an early sign. A careful review of the literature has confirmed that skin thickening, increased density and clinical signs of inflammation are the most common findings in inflammatory cancer. We report the case of a patient affected by IBC whose unique early sign of resumption on the contralateral breast was skin thickening.

The intersection syndrome: Ultrasound findings and their diagnostic value.

INTRODUCTION: The intersection syndrome is a well-known overuse syndrome of the distal forearm. It is characterized by noninfectious, inflammatory changes involving the area of intersection of the first (abductor pollicis longus and extensor pollicis brevis) and second (extensor carpi radialis longus and extensor carpi radialis brevis) extensor compartments in the dorsoradial aspect of the distal forearm. Imaging modalities used to diagnosis this syndrome include ultrasonography (US) and magnetic resonance imaging. The purpose of this report is to describe typical US findings in the intersection syndrome and to demonstrate the diagnostic value of this approach. MATERIALS AND METHODS: We reviewed US findings in 4 patients (mean age 40 years) referred to our staff for symptoms suggestive of the intersection syndrome (pain, swelling, erythema, and edema of the wrist). RESULTS: In all 4 cases, the US examination revealed peritendinous edema and synovial fluid within the tendon sheaths at the intersection between the first and the second dorsal extensor tendon compartments. DISCUSSION: Our experience shows that the intersection syndrome is associated with typical signs on US. This imaging modality can be considered a reliable tool for diagnosing this syndrome and may eliminate the need for other more expensive tests.
