To determine the historical use and utility of various lymphatic imaging modalities in Noonan syndrome (NS) patients, we performed a comprehensive literature review by collecting the published medical imaging of NS lymphatic dysplasias. We correlated imaging findings with clinical phenotypes and treatment. Our analysis of lymphatic imaging modalities provides an algorithmic approach to imaging and patient care across the spectrum of NS developmental defects. A total of 54 NS cases have been published since 1975. Using the observations reported in 15 reviewed publications, an association was made between disruptions in central lymphatic flow and poor clinical presentations/outcomes in NS patients.

Abstract Aim To highlight the importance of appropriate imaging modalities for abnormal clinical presentations. Method Xyo woman presented with severe right upper-quadrant pain to the emergency department. Prior history of colicky abdominal pain for 1 year, right-sided nephrectomy and hypertension. She stated that the current epsiode of pain was the worst so far, becoming more persistent, prompting her to call an ambulance. Cholecystitis was suspected, so a Computed Tomography abdomen/pelvis was performed. A dilated, inflamed gallbladder was noted in contact with the right psoas major, with what appeared to be an abscess in the right psoas major. Results A Magnetic Resonance Cholangiopancreatography was performed, which demonstrated that the aforementioned abscess was in fact a large cavity within the psoas major, containing up to 15 gallstones. Cholelithiasis was also seen, with common bile duct dilatation and evidence of a common bile duct stone. An Endoscopic Retrograde Cholangiopancreatography was performed, and X recovered well post-procedure with analgesia and antibiotics. Conclusions Acute cholecystitis/intra-abdominal gallstones may result in abscess/cavity formations and abnormal biliary clinical presentations. It is important therefore to fully investigate abnormal hepatobiliary imaging with multiple imaging modalities to allow for accurate diagnosis and appropriate further management of presentations.

Careful Assessment

Metatarsalgia is a common clinical conundrum that requires careful assessment. There are a variety of causes and understanding these can help manage the pain. These causes have different imaging characteristics and require specific imaging. By understanding core imaging principles and how they apply to causes of metatarsalgia, pathology can be more efficiently investigated. This article covers primary, secondary and iatrogenic causes of metatarsalgia with the most appropriate imaging modalities for each and the salient imaging findings. This article reviews the common forefoot pathologies and how they may be optimally radiologically investigated, with an emphasis on the key imaging findings.

AbstractNovel lymphatic imaging and interventional techniques are increasingly used in the diagnostic workup and treatment of pathologies of the central lymphatic system and have opened a new field of interventional radiology. The mainstay of lymphatic imaging today is magnetic resonance lymphangiography (MRL). It provides information on the anatomy of the central lymphatic system, lymphatic flow, as well as lymphatic pathologies and therefore is a valuable tool for treatment planning. There are two techniques to perform contrast-enhanced MRL: nodal dynamic contrast-enhanced MRL (nodal DCE-MRL) and interstitial transpedal MRL (tMRL). Nodal DCE-MRL yields superior information on lymphatic flow dynamics and is therefore best suited for suspected lymphatic flow pathologies and lymphatic malformations. tMRL is a technically simpler alternative for central lymphatic visualization without the need for sonographically guided lymph node cannulation. This review article describes current MRL techniques with a focus on contrast-enhanced MRL, their specific advantages, and possible clinical applications in patients suffering from pathologies of the central lymphatic system.

Abstract Background Chylothorax is a rare complication of pediatric cardiac operations that occurs more frequently in children with Noonan syndrome, a genetic disorder associated with cardiac defects and lymphatic anomalies. Case presentation We report a case of postoperative chylothorax in a 6-month-old infant with Noonan syndrome where multimodality lymphatic imaging guided management was followed. Drainage patterns of the lymphatic capillaries in the lower and upper extremities were visualized during near-infrared fluorescence lymphatic imaging (NIRFLI). Dynamic magnetic resonance lymphangiography (MRL) further identified the site of leakage in the thoracic duct and subsequently guided surgical intervention. Conclusions Application of multimodality imaging allows for greater individualization of treatment and should be considered in patients with complex cases such as those with syndromes associated with a higher incidence of chylothorax.

Calcaneal Apophysitis

Calcaneal apophysitis (Sever’s disease), is the most frequent cause of the heel pain in growing children. The diagnosisis generally made with a typical history and clinical examination. Imaging modalities including radiography and magnetic resonance imaging can help establish the diagnosis. In this case we report imaging findings of an 11-year-old boy diagnosed as Sever’s disease.J Nepal Paediatr Soc 2015;35(2):172-174

Fluid Collections

A urinoma is a collection of urine surrounded by a fibrotic wall and, in the veterinary medicine, this condition is rarely reported. The aim of this study is to describe the clinical and therapeutic features of two cats with post traumatic urinomas, with particular attention paid to the imaging findings. In both patients, well-defined anechoic fluid collections in the retroperitoneal space were identified by ultrasound examinations and the laboratory tests suggested the urinous nature of the fluid. With excretory urography, the only relevant findings revealed were the abdominal and retroperitoneal loss of detail, whereas the combination of multiple techniques in Case 1 and the delayed study in Case 2, detected contrast leakage and fluid collections in the retroperitoneal space. Both patients fully recovered after either surgical or conservative treatments. In conclusion, different imaging modalities have been helpful to properly diagnose urinomas in cats and especially combined and/or delayed studies were of paramount importance for the final diagnosis.
