A 22-year-old man presented to us with back pain for four months, inability to walk, and weakness in both lower limbs. Clinical examination revealed multiple swellings in the body, motor weakness, paresthesia, and upper motor neuron signs. Both magnetic resonance imaging (MRI) and computed tomography (CT) revealed an abnormal bone mass protruding into the spinal canal from the posterior aspect of the ninth rib through the D9-D10 neural foramen.

Introduction: Osteochondromas, also known as osteocartilaginous exostosis, are among the most common benign cartilaginous bone tumors, primarily occurring as solitary lesions. While typically found in long bones, spinal involvement is rare, accounting for only a small percentage of benign lesions in this location. Solitary osteochondromas responsible for spinal cord compression are seldom.

Background: Hereditary multiple osteochondromas (HMOs) are a rare genetic disorder characterized by the formation of multiple benign osteochondromas that can undergo malignant transformation into chondrosarcoma.
Case Description: A 24-year-old male with a history of HMO and osteochondroma surgery 4 years ago, presented with back pain and paresthesias. The magnetic resonance showed a right paravertebral infiltrating mass at the T12-L1 level causing spinal cord compression.

Feline osteochondromatosis is a spontaneous osteocartilaginous exostosis associated with feline leukaemia virus (FeLV) infection or due to a frameshift variant in the exostosin glycosyltransferase 1 (EXT1) gene. Osteochondromatosis was diagnosed in an indoor-only, 12-year-old, neutered female, Russian Blue cat. Radiographs revealed bilateral calcified proliferations in the elbow, costochondral and sternochondral joints, which distorted the normal skeletal structure.

Article Synopsis
- Benign osseocartilaginous tumors of the spine are rare, making up 1-13% of primary bone tumors and less than 10% of spinal tumors, including types like osteoid osteoma and osteoblastoma.
- These tumors vary significantly in their biology and treatment, with some responding well to anti-inflammatory drugs, while others may necessitate surgical removal to prevent recurrence.
- A multidisciplinary approach involving both surgery and chemotherapeutic methods is essential for effectively managing these tumors, and specialized classification systems aid in treatment planning.
