Epstein-Barr Virus Causing Clinical Jaundice and Acute Acalculous Cholecystitis in a Previously Healthy 17-Year-Old Girl.

BACKGROUND Infectious mononucleosis secondary to Epstein-Barr Virus is a common infection in young adults. Infection usually involves a self-limiting course of fevers, sore throat, malaise, and myalgias. Transaminitis is a relatively common complication; clinical jaundice, however, is rare. This case report highlights an uncommon complication of Epstein-Barr Virus infection in which hepatocellular injury led to clinical jaundice as well as radiologic evidence of gallbladder pathology mimicking acute calculous cholecystitis. CASE REPORT A 17-year-old girl with no prior medical history presented to our Emergency Department 1 week after being diagnosed with infectious mononucleosis. She was hemodynamically stable and her physical exam was notable for scleral icterus with right upper quadrant tenderness and positive Murphy's sign. Multiple imaging modalities performed showed gallbladder wall thickening without common bile duct dilatation. A hepatobiliary iminodiacetic acid (HIDA) scan showed evidence of hepatocyte dysfunction with normal gallbladder filling. The imaging results obtained in conjunction with her laboratory testing and active infectious mononucleosis infection confirmed the patient's presentation was a result of her Epstein-Barr virus infection and did not require surgical intervention for cholecystectomy. CONCLUSIONS This case report highlights a rare complication of Epstein-Barr Virus infection and demonstrates the utility of interpreting hepatic function testing in conjunction with relevant imaging modalities in cases of clinical jaundice. By doing so, we were able to conclude the patient's gallbladder pathology was related to acute acalculous cholecystitis (AAC) and did not warrant surgical intervention. The patient was given supportive care measures and made a full recovery.

Splenic lacerations and return to play: case report of 2 professional hockey players.

BACKGROUND: Several sports medicine reviews have highlighted a 3- to 6-month time frame for return to play after splenic lacerations. These reviews are based on several well-defined grading scales for splenic injury based on computed tomography (CT). None of the articles suggest that serial CT scanning is necessary for follow-up; some even indicate that it has no role in the management of these injuries. HYPOTHESIS: With proper follow-up and possibly the use of serial CT scanning or other imaging modalities, it may be possible for athletes to safely return to play sooner than what current guidelines recommend. STUDY DESIGN: The authors present 2 cases of professional hockey players who both suffered grade III splenic lacerations while playing. METHODS: Both players were treated conservatively and monitored with serial CT scanning until radiographic and clinical findings suggested complete healing. RESULTS: Both players were able to return to full-contact professional hockey within 2 months after suffering grade III splenic lacerations. Neither athlete suffered any complications after his return. CONCLUSIONS: With CT scanning, 2 athletes were able to return to play earlier (2 months) than previously recommended (3-6 months) without compromising their safety. CLINICAL RELEVANCE: Additional cases must be examined before outlining more definitive recommendations regarding splenic lacerations in sports, but it is possible that elite athletes may return to play sooner than what the current literature recommends.

Reduction of radiation exposure in pediatric patients with trauma: cephalic stabilization improves adequacy of lateral cervical spine radiographs.

INTRODUCTION: Plain radiographs continue to play a role in cervical spine clearance. Inadequate radiographs commonly necessitate repeat x-rays or computed tomography imaging (10 × radiation dose). We have used the technique of cephalic stabilization (CS) to improve the results of plain radiographs. Cephalic stabilization lateral radiographs are obtained, with one assistant applying traction to the arms while another placing fingers in the patient's ears and stabilizing the head. This study tests the hypothesis that CS improves visualization of the cervicothoracic junction during lateral cervical spine radiographs. METHODS: A 2-year review of institutional pediatric trauma registry identified 46 patients with CS, matched 1:3 with controls. Randomized lateral radiographs were evaluated independently by 2 pediatric radiologists to determine adequate visualization of the craniocervical and cervicothoracic junctions. Reviewers were blinded to CS through image cropping. RESULTS: The proportion of adequate visualization of the cervicothoracic junction was 0.85 for cases with stabilization and 0.60 for controls. Odds of obtaining adequate visualization with stabilization are 3.8 times those without stabilization (P = .001) and were even greater for patients younger than 13 years. CONCLUSIONS: Cephalic stabilization improves visualization of the cervicothoracic junction in lateral cervical spine radiographs and can reduce radiation exposure in patients who would otherwise require further imaging.

Imaging of unusual perineal masses.

OBJECTIVE: The purpose of this article is to describe the radiologic features of unusual tumors that occur in the perineum. CONCLUSION: The perineal space is often overlooked because of the infrequency of abnormalities. Accurate image interpretation and visualization of extent of pathology is important for proper management. Trauma and infectious diseases occur in the acute setting, whereas tumors are common in the chronic setting. Cross-sectional imaging plays a crucial role in depicting perineal anatomy and evaluating the extent of disease.
