Role of magnetic resonance spectroscopy in differential diagnosis of solitary pulmonary lesions

PURPOSEThe aim of our study was to evaluate the availability of magnetic resonance spectroscopy (MRS) for the differentiation of benign or malignant pulmonary nodules and masses.METHODSA total of 59 patients (45 male, 14 female) with pulmonary nodules and masses were included in this prospective study. MRS was applied to the pulmonary lesions of the patients and choline levels were determined. Afterwards CT-guided percutaneous needle biopsy was performed. According to the biopsy results, pulmonary lesions were benign in 25 patients and malignant in 34 patients.RESULTSCholine levels were significantly higher in malignant lesions compared with benign lesions (p 1.65 µmol/g compared to those with choline levels ≤1.65 µmol/g (p < 0.001).CONCLUSIONMRS is a noninvasive method that can be used in the differential diagnosis of pulmonary nodules and masses

Ultrasound versus computed tomography scan findings in pediatric blunt abdominal traumas

Objective: We aimed to evaluate the performance of ultrasonography (US) versus computed tomography (CT) scan in detecting intra-abdominal injury among pediatric patients with blunt abdominal trauma.&nbsp;Methods: Pediatric patients aged&lt;18, who were admitted to the emergency department (ED) due to abdominal trauma and underwent both US and CT scan were evaluated retrospectively.&nbsp;Results: A total of 732 pediatric patients were included in this study. Pathology was detected on US of 418 (57.1%) cases, whereas, intra-abdominal pathology was detected in CT scan of 359 (48.7%) cases. The sensitivity of US in detecting pathology (fluid and/or organ injury) was 95.3%, and its specificity was 79.6%. The sensitivity of US in detecting free fluid was 94.9%, and its specificity was 80.5%. In patients with unstable and stable hemodynamic, the sensitivities of US in detection of pathology (fluid and/or organ injury) were 97.6% and 91.6%, and its specificities were 74.3% and 80.9%, respectively.&nbsp;Conclusions: In our study, the sensitivity of US in terms of detecting pathology in pediatrics with blunt abdominal trauma was high, whereas the specificity of US was low

Case Report Bilateral Wallerian Degeneration of the Pontocerebellar Tracts

Wallerian degeneration is the process of progressive demyelination and disintegration of the distal axonal segment following the transection of the axon or damage to the neuron. We report a case of a patient with Wallerian degeneration of the pontocerebellar tracts. She had a history of a pontine infarction 3 months ago. Wallerian degeneration of pontocerebellar tracts is seen bilaterally and symmetrically and is more visible in the middle cerebellar peduncles. Along the middle cerebellar peduncles hyperintense signal was detected on T2 weighted images. Wallerian degeneration of pontocerebellar tracts is a rare entity. It can occur bilaterally after a large pontine infarction. Magnetic resonance imaging seems to be the most effective technique for detection of Wallerian degeneration. In this report we want to mention this rare entity and to prevent wrong diagnosis
