Co-occurrence of compression syndromes: celiac axis stenosis, superior mesenteric artery and nutcracker syndrome.

Moreno Márquez et al. report an association between arcuate ligament syndrome (ALS) and the "nutcracker" phenomenon (compression of the left renal vein). The case illustrates the association between several syndromes, which all involve compression of vascular or gastrointestinal structures: arcuate ligament syndrome, superior mesenteric artery syndrome (SMAS) or Wilkie's syndrome, the "nutcracker" syndrome and May-Thurner syndrome (compression of the left iliac vein).

Inflammatory myofibroblastic tumours: a pictorial review.

Objectives: To present the most important characteristics of inflammatory myofibroblastic tumours (IMTs) arising in different locations of the body with histological correlation.

Methods: To review the symptoms and main radiological findings of IMTs. On ultrasonography (US), these tumours can appear as hypoechoic or hyperechoic masses and a variable Doppler appearance with increased vascularity.
