Recurrent Non-Ossifying Fibroma in Shaft of Distal Radius- A Rare Case.

INTRODUCTION: Non-ossifying fibroma are is a common benign lesions found in children. Usually, they are found in cortical bone in metaphysis, but they can also be seen in cancellous bone. Theses lesions are known to regress spontaneously. Usually, it is asymptomatic and an incidental finding on radiograph. No intervention is required. Here, we are reporting a case of symptomatic non-ossifying fibroma of radius with unusual characteristics which required surgical intervention. CASE REPORT: An 11-year-old skeletally immature girl presented to us two 2 years back with pain and swelling over the right forearm without any restriction of moments and other constitutional symptoms. She was diagnosed to have non-ossifying fibroma and had underwent surgery for the same 4years back. Radiographic and higher imaging studies suggested non-ossifying fibroma. Since the lesion was painful and the child had difficulty in carrying heavy objects, we decided to intervene. Tumour tissue was thoroughly curetted and the defect was filled with artificial bone substitute. Biopsy confirmed the diagnosis of non-ossifying fibroma and post-operative radiograph showed some residual tumour which was noted even at one 1-year follow-up X-ray. On 3-years follow-up,the patient was symptom-free with no residual lesion and complete incorporation of the artificial bone substitute. CONCLUSION: Though Although most of the NOF regress completely without intervention, large and symptomatic lesions in unusual location require to be surgically treated. The natural history of the lesion - spontaneous regression also aids in the management.

Posttraumatic thoracic epidural capillary hemangioma - A rare case report.

BACKGROUND: Capillary hemangiomas are benign vascular lesions commonly seen in subcutaneous tissues. The most common site of origin is from the vertebral body, and only a few cases of isolated lesions in thoracic epidural space, especially after trauma, have been reported in the literature. CASE DESCRIPTION: We report a case of 63-year-old male with progressive bilateral lower limb weakness and exaggerated lower limb deep tendon reflexes without bowel and bladder involvement. His history revealed T7 fracture with paraparesis which was treated surgically, and implants were removed a year later. MRI showed an epidural lesion from T6-T8 extending into the right T7-8 foramen which showed hypointensity on T1, hyperintensity on T2, and homogenous enhancement in contrast images with severe cord compression. Laminectomy was done and the lesion was removed en bloc. Histopathological examination revealed it to be capillary hemangioma. The neurology came back to normal after 3 months. CONCLUSION: Although capillary hemangiomas are rare lesions, it has to be considered in the differential diagnosis of epidural space-occupying lesions which require early surgical removal to prevent a progressive and permanent neurological deficit.
