Significant progress in improving outcome for patients with oncohematological diseases are attributed to intensive chemotherapy, bone marrow transplantation, platelet transfusions, development of new imaging techniques, new antimicrobials and others. All these advances increase the survival of these patients which in turn increases the frequent of risk of infections that are substantial cause of morbidity and mortality in these patients.
The purpose of this exhibit is to show the spectrum of infections in these patients; describe the imaging finding according to the etiology and associated factors.

There are a number of factors that need to be considered in order to interpret abnormalities seen on radiology as the type of hematological disease, stage of the hematological disease, treatment phase, profile of immunodeficiency, treatment for infection received, patient history and clinical signs. For example, according to type of immunosuppression there are different spectrum of infections but leukemia affect all types of immunosuppression that include neutropenia, T cell defect and B cell defect.

Ovarian masses are the most common tumours in paediatric population. Although there is data available on imaging characteristics of different types of masses, benign and malignant, there is no standard imaging classification system. The Ovarian-Adnexal Reporting and Data System Ultrasound (O-RADS) classification system currently used for adults, has not been extensively applied and tested in children and adolescents. Read More

Bezoars are an uncommon cause of small bowel obstruction (SBO) in children. Trichobezoars are typically seen in adolescent girls who swallow their hair. Lactobezoars are another unusual cause of intestinal obstruction in neonates/infants. Phytobezoars, foreign body bezoars and pharmacobezoars are other types of bezoars. CT is a useful tool in diagnosing the cause of SBO, however, SBO caused by bezoars may not be detected on a CT exam as it presents as faeces like material proximal to the transition point. Ultrasound (US) can help differentiate a bezoar from faeces. The diagnostic signs of a bezoar on US include an echogenic, arc-like surfaced intraluminal mass, strong posterior acoustic shadowing and twinkling artefacts from the front of the mass resulting from the rough hard surface and high acoustic impedance differences within the internal structure of a bezoar. These features are not seen with faecal material.

We present two cases of bezoar induced SBO. The first case was a small intestinal trichobezoar in an 11 year old female child who presented with abdominal pain and bilious vomiting since 4 days. US demonstrated dilated small bowel with classic appearances of a bezoar in distal ileum. CT was not done in this instance and patient underwent surgery based on US findings. Same patient was also shown to have a large gastric bezoar on further endoscopic and ultrasound evaluation. Second case was a lactobezoar in a 9 month old infant that presented with copious bilious aspirates in NG tube, post difficult hernia reduction. CT demonstrated acute SBO with transition point at IC junction and faeces like intraluminal material proximal to it. US again showed characteristic appearances of a bezoar thus clinching the diagnosis. First patient underwent extraction via enterotomy and the second patient was treated with fragmentation and milking out.

Our cases highlight following learning points: 1. US shows characteristic appearances and improves diagnostic accuracy in conjunction with CT thus helping radiologists to quickly and easily diagnose bezoar. US can also suffice as first line and only imaging investigation needed. 2. Lactobezoar should be kept as a differential for SBO in neonates/infants. 3. In cases of intestinal bezoars, possibility of further proximal/gastric bezoars must be explored. Read More

Introduction: Radiology residents typically receive limited exposure to dental radiology during their training. However, they frequently encounter dental pathologies while scanning the brain or maxillofacial regions for other clinical purposes. Understanding basic principles of dental radiology is essential for accurately assessing maxillo-facial computed topography (CT) scans, as these pathologies can go under-recognized and potentially have significant impact on diagnosis and treatment. Purpose: This study aims to highlight the importance of dental radiology knowledge for radiology residents and fellows. By recognizing dental pathologies in imaging studies, radiologists can contribute to better management and care of pediatric patients. Discussion: This will be a pictorial educational exhibit obtaining cases from the teaching database at a pediatric tertiary care hospital. We will present cases in a pictorial format, primarily focusing on conventional CT, orthopantomograms (OPG), and cone-beam computed topography (CBCT). The discussion will cover various dental pathologies encountered, including: Impacted Dental Prosthesis: Leading to maleruption of the teeth, a dentist’s perspective; Prosthesis Malfunction: Identifying signs of failure and the implications for patient care; Post-Maxillofacial Surgery Complications: Examining alterations due to mechanical stress on the mandible, leading to exostosis and other lesions; Dental issues in Syndromes affecting the Faciocranium: Dental issues in well-known syndromes such as Pierre Robin, hemifacial microsomia, Goldenhar syndrome, etcetera; Unexpected Findings: Perforation of the mandibular fossa into the middle cranial fossa as a sequalae of juvenile inflammatory arthritis and trauma.
