Chondroma is a benign cartilaginous neoplasm, rarely encountered in the lumbar spine. We report a case involving a 70-year-old female who presented with lower limb radiating pain that started four years ago. Although no pronounced muscle weakness was noted, the patient experienced progressively worsening radiating pain in the L4 dermatome. Initial evaluation, including magnetic resonance imaging (MRI) performed at another medical facility, suggested a potential lesion associated with left L4–5 lumbar disc herniation. Despite non-surgical interventions, the patient experienced limited symptomatic relief, prompting her to seek further care at our clinic. Subsequent contrast-enhanced MRI conducted at our facility revealed a mass exhibiting peripheral rim enhancement surrounding the L4 nerve root. Suspecting a neurogenic tumor, we decided to perform surgical excision of the mass. Postsurgery, histopathological analysis confirmed the presence of hyaline cartilage with lobular architecture and chondrocytes in lacunae, leading to the conclusive diagnosis of chondroma. Following the surgical procedure, the previously reported radiating pain exhibited notable improvement.
