Giant Parietal Wall Lipoma with Intrathoracic Extension in A 7 Years Old Boy: A Case Report

Parietal wall lipomas are rare, benign tumors that consist of adipose tissue.When these lipomas grow to a giant size and extend into the thoracic cavity, they present unique diagnostic and management challenges, particularly in pediatric patients.We report a case of a 7-year-old male who presented with a large, progressively enlarging mass on the anterior chest wall.Clinical examination revealed a mobile, non-tender mass measuring approximately 12 cm in diameter.Imaging studies, including chest X-ray, CT, and MRI, revealed a well-defined lipoma with 30% intrathoracic extension, compressing adjacent lung tissue.The patient exhibited mild respiratory symptoms, but no signs of distress or hemodynamic instability.Surgical excision was performed under general anesthesia, and the mass was successfully removed without complications.Histopathological examination confirmed the diagnosis of a benign lipoma.Postoperatively, the patient recovered well, with no signs of recurrence during a 6-month follow-up.This case highlights the importance of considering giant parietal wall lipomas with intrathoracic extension in the differential diagnosis of pediatric chest masses.Early diagnosis and timely surgical intervention are critical in preventing potential complications such as respiratory distress.
