Spontaneous Intrathoracic Rupture of Abdominal Neuroblastoma in a 2-year-old Child: A Rare Case Report.

Neuroblastoma (NB) tumor rupture, typically intra-abdominal, is a rare and life-threatening condition with a poor prognosis, often associated with large aggressive tumors. Intrathoracic ruptures, rarely reported, may result from thoracic NB or malignant invasion. We present the first case of spontaneous intrathoracic rupture in a 2-year-old boy with abdominal NB.
