RESUMO
Rhabdomyolysis is a complex medical condition in which insufficient energy supply to muscles results in the destruction of skeletal muscle and leakage of toxic intracellular substances into the systemic circulation. The common cause of rhabdomyolysis is a direct traumatic injury; however, it can also occur due to non-traumatic factors, including infection, toxins, and drugs. Rhabdomyolysis as an adverse effect of antipsychotic medication is not well understood. Peripheral neuropathy is a rare complication of rhabdomyolysis. Here, we present a case of a 22-year-old woman who presented to the emergency department with right thigh pain following an antipsychotic drug overdose and 3 days of loss of consciousness. There was no history of trauma to her leg. Physical examination, diagnostic testing, and imaging indicated a diagnosis of rhabdomyolysis and peripheral neuropathy. The patient underwent an incision with drainage, a muscle biopsy, and was treated with hydration, after which her condition improved, and she was discharged. Follow-up testing indicated lasting nerve injury. Peripheral neuropathy can occur even in patients with rhabdomyolysis without compartment syndrome. Awareness of this rare complication may help in initiating early interventions to minimize irreversible sequelae.
RESUMO
Purpose@#To determine the multidetector CT (MDCT) findings that differentiate adenomyoma of the ampulla of Vater (AOV) from localized adenocarcinoma of the AOV. @*Materials and Methods@#Sixteen and 30 patients with adenomyoma and localized adenocarcinoma of the AOV, respectively, were evaluated using MDCT. We analyzed the size and attenuation value and presence of uniform enhancement of the lesions, diameters of the extrahepatic bile duct (EHD) and main pancreatic duct, presence of regional lymph node enlargement, and laboratory findings. We determined the independent findings for differentiating adenomyoma from localized adenocarcinoma of the AOV using multivariate analysis. @*Results@#The size of the lesion and diameter of the EHD were significantly smaller for adenomyoma than those for localized adenocarcinoma of the AOV (all p < 0.001). In multivariate analyses, a lesion size of ≤ 1.3 cm, an EHD diameter of ≤ 1.3 cm, and an alanine transaminase level of ≤ 31 IU/L significantly differentiated adenomyoma from localized adenocarcinoma of the AOV. When all of these three findings were met, the specificity for adenomyoma of the AOV was 93.3%. @*Conclusion@#MDCT imaging may facilitate the differential diagnosis of adenomyoma and localized adenocarcinoma of the AOV based on the size of the lesion and diameter of the EHD.

RESUMO
Voiding cystourethrography (VCUG) demonstrates the anatomy of the urinary system and is used to detect the presence/absence of vesicoureteral reflux. It is the most important modality for urological fluoroscopic examination in children. For improved patient care, it is important to understand and perform VCUG appropriately. Therefore, an in-depth review of VCUG protocols and techniques has been presented herein. In addition, tips, tricks, and pitfalls associated with the technique have also been addressed.
