European Federation of Societies for Ultrasound in Medicine and Biology (EFSUMB) Position Statement on Dermatologic Ultrasound

Dermatologic ultrasound is a recent application of ultrasound for the evaluation of healthy skin and appendages and their diseases. Although the scientific literature regarding this application is still not sufficient for evidence-based guidelines, general recommendations issued by scientific societies are necessary. The EFSUMB (European Federation of Societies for Ultrasound in Medicine and Biology) steering committee for dermatologic ultrasound has developed a series of consensus position statements regarding the main fields of dermatologic ultrasound (technical requirement, normal skin and appendages, inflammatory skin diseases, tumoral skin diseases, aesthetic dermatology and practice-training requirements). This document is the foundation for future evidence-based recommendations and guidelines for dermatologic ultrasound practice.

Do we need a cancer screening in patients with idiopathic deep vein thrombosis?

AIM

To review the literature concerning the need for a cancer screening battery to diagnose a hidden cancer in patients presenting with idiopathic venous thromboembolism (VTE).

MATERIALS AND METHODS

Data from computerized database programs (Medline, Ovid) was retrieved. A review of the literature regarding studies on cancer screening in patients with idiopathic VTE was performed and our own policy included.

RESULTS

Patients with VTE have a higher rate of malignancy which may still be undiagnosed. During follow-up of patients with idiopathic VTE, the incidence of cancer increases and is more likely associated with a worse prognosis. Limited diagnostic work-up in patients with idiopathic VTE allows the diagnosis of a hidden malignancy in about half of the cases with a sensitivity of 48 %. Extensive screening of cancer with idiopathic VTE allows less of a delay and earlier stage at diagnosis with a 93 % sensitivity. However, reduced cancer-related mortality is not statistically significant. A two-fold fatal PE and more than 3-fold fatal bleeding are registered in VTE patients with hidden cancer compared to patients without cancer. The major risk factors for hidden cancer are old age, anemia, idiopathic and bilateral deep vein thrombosis.

CONCLUSION

There is no consensus regarding the benefit of extensive screening in patients presenting with idiopathic VTE. Clear diagnostic work-up guidelines are not yet available. A cost-effective diagnostic algorithm for cancer screening in patients with idiopathic VTE is needed.

Pitfalls of the Lactating Breast on Computed Tomography

Breasts are usually only incidentally included in computed tomography (CT) scans of the abdomen and chest in spite of the fact that pathologic findings are not rare. Because postpartum women are normally healthy, they rarely require examination; therefore, the presentation of lactating breasts on a CT scan is poorly known. The most common postpartum breast feature is engorgement, which is characterized by painful swelling associated with a sudden increase in milk volume, lymphatic and vascular congestion, and interstitial edema. Its appearance on a CT scan does not seem to have been described in the literature to date. The CT picture of a lactating breast shows the enlarged gland with bilateral cord- and mass-like hyperattenuated tissue. After abrupt cessation of breast-feeding, the edema component supervenes and breast tissue may become hypoattenuated. In such cases, further ultrasound evaluation is needed. We present 3 cases of postpartum breast engorgement as seen on CT.
