Transdiaphragmatic intercostal hernia (TDIH) is a rare condition involving simultaneous disruption of the diaphragm and intercostal muscles, allowing abdominal organs to herniate into the chest wall. It is usually traumatic and spontaneous cases are uncommon and can be easily overlooked. We report the case of a man in his late 60s with six years of progressive right chest wall swelling and recent vomiting and breathlessness. Initial imaging was misinterpreted as pleural effusion, but a computed tomography confirmed a five cm diaphragmatic defect with bowel herniation through the 7th –8th intercostal space. Prompt recognition is vital, as delayed diagnosis may lead to bowel obstruction, strangulation, and life -threatening complications

Medulloblastoma is the most common form of childhood primary brain tumour arising from the
cerebellar vermis. It is classified as WHO grade IV embryonal tumours and currently at least four
histological variants have been established. Only few case reports been published on the imaging
features of the medulloblastoma with excessive nodularity variant. We report the MRI features of a rare
case of medulloblastoma with excessive nodularity in a child which is confirmed by histopathology.
