Calcifying fibrous tumor involving the paraspinal region of a child: A rare case report

Introduction: Calcifying fibrous tumor (CFT) is a rare, benign tumor characterized by hyalinized fibrous tissue with distinctive psammomatous and dystrophic calcifications. It is a soft-tissue tumor found in various organ systems. There are only a few reported cases of CFT involving the paraspinal region. Case Report: We report a 28-month-old female with a paravertebral soft tissue mass. Ultrasound and magnetic resonance imaging (MRI) revealed a well-defined, lobulated lesion in the left paravertebral muscles extending approximately from T9 to L2. The patient had a needle core biopsy and a surgical resection of the tumor. The pathologic diagnosis reported was CFT of the longissimus thoracic muscle. Conclusion: Postoperative recovery was uneventful and there was no recurrence after follow-up.
