Lymphoma is the most common mediastinal mass in children. Obtaining tissue for diagnosis can be challenging due to reported low diagnostic yield and risk of cardiorespiratory collapse, especially in the setting of anesthesia. We report our experience with biopsy of mediastinal masses, report the diagnostic rate for lymphoma and biopsy/anesthetic complications related to the procedure. Read More

Diagnosing paediatric TB can be challenging due to non-specific signs and symptoms and difficulties in getting a microbiological confirmation. Diagnosis relies mainly on symptoms and chest X-ray (CXR), with hilar or mediastinal lymphadenopathy as the most common finding. However, CXR has poor inter- and intra-reader agreement for mediastinal lymphadenopathy. Ultrasound (US) does not expose children to ionizing radiation; is repeatable and due to the recent development of portable, low-cost US machines it can be used at the point of care and is cost-effective.
We investigated clinician-performed mediastinal US, comparing with CXR, for the detection of lymphadenopathy in children with suspected pulmonary TB. Read More

A 33-day old infant was presented to the hospital after difficulty breathing and breastfeeding. The patient had a history of hyperbilirubinemia with acute hypoxic respiratory failure, felt secondary to a mediastinal mass, severe metabollic lactic acidosis, anemia, and acute severe coagulopathy.

This patient was denied vitamin K prophylaxis at birth at discretion of the parents. Vitamin K deficency subsequently caused coagulopathy and jaundiced skin, which associate with Vitamin K Deficiency Bleeding.

Presented is a case of thymic hemorrhage in a neonate demonstrating as a mimic lesion on imaging. Further invasive work-up to distinguish etiology of mass was not required demonstrating biopsy or surgery is not always necesary for diagnostic purposes. The identified symptoms represent the potential sequelae of thymic hemorrhage. Read More

Diagnosing pediatric pulmonary tuberculosis (PTB) may be challenging as getting microbiological confirmation is difficult. Chest X-Ray (CXR) involves radiation exposure and has poor inter-reader agreement. Mediastinal lymphadenopathy can also be detected by mediastinal ultrasound (US). We describe technical aspects of performing mediastinal US and the findings in children with suspected PTB. Read More

Mediastinal tumors comprise a range of congenital, neoplastic and inflammatory tumors. While many benign and malignant lesions can be differentiated by CT appearance and attenuation values, many cannot be reliably separated. The purpose of this paper is to evaluate the feasibility of dual-energy computed tomography (DECT) in differentiating a spectrum of mediastinal tumors in children Read More
