Sivasankar Jayakumar, Sanjana Venkateswaran, Sathish Manivel, Balamurali G


Congenital infantile fibro-sarcomas (CIFS) are rare, locally aggressive mesenchymal tumors that usually develop from soft tissue of distal extremities. CIFS arising from paraspinal region are extremely rare and only few cases have been reported. A left thoracic paraspinal swelling in a female fetus was noted on 20-week antenatal scan of a primigravida. The swelling was monitored with regular antenatal scans. The baby was born at term and was well at birth. Serum AFP and Beta HCG were within normal age limits. MRI scan confirmed an aggressive tumor infiltrating the paraspinal muscles but not the spinal cord. The mass grew very rapidly in size within a few days, and was excised on day 7 of life. Histopathology and Immunohistochemistry diagnosed the mass to be a Fibrosarcoma. No chemotherapy or radiotherapy was given. The baby is well with no recurrence or residual deformity or neurological deficit after 18 months of follow up.Paraspinal CIFS are extremely rare but can be detected antenatally as early as 20 weeks of gestation. Complete surgical excision is the treatment of choice.
