An Unusual Paediatric Neck Mass: Cervical Lipoblastoma with Spinal Involvement.

Lipoblastoma is a benign tumour derived from embryonic white fat and is more commonly seen in children. Spinal involvement is rare, with only 14 cases reported to date. We report a case of a 7-year-old boy who was presented with an asymptomatic right neck swelling for 5 years. Clinical examination revealed a soft multilobulated mass causing tracheal deviation with normal neurological examination. Ultrasound, Computed tomography and Magnetic resonance imaging showed a lipomatous lesion with extension to spinal foramina at C3-C5 causing displacement of the spinal cord. Near total excision of the tumour was done with a small remnant left behind at C3-C4 as it was tightly adhered to the vertebral artery. Histopathological samples were consistent with lipoblastoma. The patient developed ipsilateral ptosis and pupillary myosis which improved on the second-month postoperative review; no other neurological deficit was noted, and a follow-up cervical MRI showed no recurrence.
