Lipoblastoma is a rare neoplasm arising from embryonic mesodermal cell rests and occurs most commonly in male infants in the first decade of life. While demonstrating the exponential growth of a true neoplasm these lesions do not typically invade surrounding structures but rather present with compressive symptoms. We report a case of a three year old male pre-school child whom presented to our unit with an asymptomatic paraspinal subcutaneous mass on his upper back. Clinical examination revealed no signs of spinal dysraphism and his neurological examination was normal. MRI imaging revealed the typical signal characteristics of a lipomatous mass with a subcutaneous component, extension into and enlargement of the adjacent T5/T6 foramen with thecal impingement, and anterior intra-thoracic spread. A gross total resection was achieved through a posterolateral extra-pleural approach. Post-operative histology reported the lesion to be a lipoblastoma. According to our literature review this is the second case of a paraspinal lipoblastoma with demonstrated radiological and intra-operatively confirmed multi-directional spread.
