ABSTRACT
Teaching Point: When a renal angiomyolipoma (AML) is incidentally detected on imaging, the venous system should be assessed for intravascular fat component.
ABSTRACT
Teaching Point: Hypophysitis is a side effect of Ipilimumab that should not be confused with other conditions on imaging, such as metastasis.
ABSTRACT
Teaching point: This case emphasizes the importance of the "tail sign" to sort the differential diagnosis of soft tissue tumors by highly suggesting schwannoma.
ABSTRACT
Teaching Point: This clinical case shows the importance of also examining the arteries when investigating suspected deep venous thrombosis.

Metastatic infiltration of a peripheral plexus, also named metastatic plexopathy (MP), often results in severe pain and muscular weakness. This rather rare event may have a dramatic impact on the quality of life of patients affected by cancer. We hereby report a rare case of painful MP of the left cervicobrachial plexus presenting as the inaugural manifestation of poorly differentiated large-cell lung carcinoma in a 53-year-old patient. This responsible lung carcinoma was fortuitously diagnosed during MRI of the brachial plexus (BP). Complementary cancer staging was completed by contrast-enhanced multidetector CT, 18-fludeoxyglucose-positron emission tomography/CT and colour Doppler ultrasound of the BP. Although MRI remains the gold standard method for imaging the BP, our reported case emphasizes the alternative diagnostic capabilities of contrast-enhanced multidetector CT and ultrasound and confirms the high specificity of 18-fludeoxyglucose-positron emission tomography/CT in distinguishing brachial MP from secondary radiation plexopathy.
ABSTRACT
Intradural disc herniation (IDH) is very rare. Most diagnoses were surgical but with the improvements in magnetic resonance imaging (MRI) it has become possible to preoperatively diagnose intradural migration of disc in some cases. We report a case with very specific imaging features in MRI, well correlated with the surgical findings.
ABSTRACT
We report two cases of elderly patients presenting with life-threatening complications due to inadvertent accidental ingestion of blister pill packs (BPPs). The first patient presented with obstruction followed by anemia and finally perforation of the small bowel. The second presented with rapidly lethal mediastinitis due to a large perforation of the lower esophagus. The responsible BPPs were identified by multidetector computed tomography and the best result in their characterization was obtained through maximal intensity projections and volume rendering reformations.

Direct transaortic implantation (TAo) has been described as a new alternative approach for transcatheter aortic valve implantation in patients with unsuitable transfemoral access. TAo is usually achieved through an upper ministernotomy or, more recently, through a right thoracotomy in the second intercostal space. We describe here our first experience with a fully thoracoscopic approach that allowed successful deployment of a 23-mm Edwards SAPIEN valve.

We report a very rare case of internal hernia of the small bowel through a large congenital defect of the falciform ligament. A complete preoperative diagnosis was possible by 64-row multi-detector row computerized tomography. The identification of the characteristic anatomic features and landmarks of the obliterated umbilical vein-ligamentum teres-was the diagnostic key.
