Clinical imaging

Medial patellofemoral ligament (MPFL) reconstruction is a relatively new surgical technique for the treatment of recurrent patellar instability and dislocation. Radiologic findings following MPFL reconstruction are not well described in the existing literature. Here, we review the anatomy and biomechanics of the MPFL, review imaging findings following double-bundle MPFL reconstruction, and show examples of complications arising from reconstruction.

This article is the first portion of a two-part review that illustrates the normal appearance of the cerebellum and posterior fossa on prenatal ultrasound and MRI and on postnatal diagnostic imaging studies. Classification and terminology of posterior fossa abnormalities in the literature are confusing due to evolution of concepts and sometimes lack of consensus. Accurate classification of posterior fossa anomalies is important for predicting fetal outcome and for appropriate counseling. In Part 1 of this review, prenatal and postnatal imaging techniques for assessing the posterior fossa will be discussed, followed by a discussion of how cerebellar malformations may be classified.

Case Reports
Successful catheter-directed thrombolysis of a massive pulmonary embolism in a patient after recent pneumonectomy.
Massive pulmonary embolism (PE) after major thoracic surgery is an uncommon but life-threatening event that is challenging to manage. At present, the treatment of acute PE is either anticoagulation with or without systemic thrombolytic therapy. ⋯ The patient was successfully and safely treated with catheter-directed thrombolysis. To our knowledge, this is the first patient treated in this fashion.

The purpose of this retrospective monocenter study was to evaluate a monophasic multidetector computed tomography (MDCT) protocol with a fixed delay for patients with polytrauma. A total of 2086 patients were evaluated retrospectively. ⋯ In the venous phase, we detected injuries of parenchyma and localized ongoing bleedings in regard to the clinical follow-up, with regard to the easy feasibility and the quickness with only one scan. Monophasic venous injection protocol can detect all injuries in the whole-body MDCT for patients with polytrauma.
