Abstract One of the most common urological emergencies encountered in pediatric patients in the emergency department (ED) is the acute scrotum. We present the case of a 4-month-old male that presented to our community ED with scrotal swelling and vomiting of 16-hours duration. He was diagnosed with a functional testicular torsion from an incarcerated inguinal hernia, transferred to a hospital with pediatric urological capabilities and was taken to the operating room ~2 hours later. His hospital course was unremarkable, and he was discharged on day 3, having made a full recovery without any loss of bowel or testicle. There have only been a handful of cases in the literature of a pediatric patient presenting with a functional testicular torsion as a result of spermatic cord compression from an indirect inguinal hernia, with no reported cases of complete salvage at nearly 18 hours since symptom onset.

Prompt Treatment

The children presenting with acute scrotum have many diseases in differential diagnosis and testicular torsion in undescended testis and normal testis is an important consideration. Torsion of the testis, or more correctly, torsion of the spermatic cord, is a surgical emergency because it causes strangulation of gonadal blood supply with subsequent testicular necrosis and atrophy. In most of cases history and physical examination are sufficient to make an accurate diagnosis. While other causes may require simple treatment but torsion require immediate exploration to save the testis. Early diagnosis and prompt treatment is essential to help such children.

OBJECTIVEMany patients with medically intractable epilepsy have mesial temporal sclerosis (MTS), which significantly affects their quality of life. The surgical excision of MTS lesions can result in marked improvement or even complete resolution of the epileptic episodes. Reliable radiological diagnosis of MTS is a clinical challenge. The purpose of this study was to evaluate the utility of volumetric mapping of the hippocampi for the identification of MTS in a case-controlled series of pediatric patients who underwent resection for medically refractory epilepsy, using pathology as a gold standard.METHODSA cohort of 57 pediatric patients who underwent resection for medically intractable epilepsy between 2005 and 2015 was evaluated. On pathological investigation, this group included 24 patients with MTS and 33 patients with non-MTS findings. Retrospective quantitative volumetric measurements of the hippocampi were acquired for 37 of these 57 patients. Two neuroradiologists with more than 10 years of experience who were blinded to the patients' MTS status performed the retrospective review of MR images. To produce the volumetric data, MR scans were parcellated and segmented using the FreeSurfer software suite. Hippocampal regions of interest were compared against an age-weighted local regression curve generated with data from the pediatric normal cohort. Standard deviations and percentiles of specific subjects were calculated. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were determined for the original clinical read and the expert readers. Receiver operating characteristic curves were generated for the methods of classification to compare results from the readers with the authors' results, and an optimal threshold was determined. From that threshold the sensitivity, specificity, PPV, and NPV were calculated for the volumetric analysis.RESULTSWith the use of quantitative volumetry, a sensitivity of 72%, a specificity of 95%, a PPV of 93%, an NPV of 78%, and an area under the curve of 0.84 were obtained using a percentage difference of normalized hippocampal volume. The resulting specificity (95%) and PPV (93%) are superior to the original clinical read and to Reader A and Reader B's findings (range for specificity 74%–86% and for PPV 64%–71%). The sensitivity (72%) and NPV (78%) are comparable to Reader A's findings (73% and 81%, respectively) and are better than those of the original clinical read and of Reader B (sensitivity 45% and 63% and NPV 71% and 70%, respectively).CONCLUSIONSVolumetric measurement of the hippocampi outperforms expert readers in specificity and PPV, and it demonstrates comparable to superior sensitivity and NPV. Volumetric measurements can complement anatomical imaging for the identification of MTS, much like a computer-aided detection tool would. The implementation of this approach in the daily clinical workflow could significantly improve diagnostic accuracy.
