Abstract

Osteochondroma is a benign outgrowth of bone and cartilage and is one of the most common bone tumors that usually occurs in the long bones but rarely involves the spine [1]. In spine, it occurs most commonly in the cervical and upper dorsal segments [2]. It shows male preponderance and an average age presentation is approximately 32+4.6 years [3]. Lumbar osteochondroma can be asymptomatic or cause symptoms like pain, radioculopathy/myelopathy, or cosmetic deformity. Osteochondromas are also known as exostosis, the most common primary bone tumors comprising one-third of all benign bone tumors. They can be solitary (90% of cases) or multiple in the form of hereditary multiple exostosis [4]. Here we report a case of 53 year old male, came with left abdominal pain, in which lumbar osteochondroma was an incidental finding on Computed Tomography (CT).

Case Presentation

A 53 year old male came to the casualty with complaints of pricking left abdomen pain since one week, which had aggravated one day prior. The patient was evaluated for the same. His physical examination, neurological examination and blood investigations were unremarkable. Ultrasound abdomen revealed left ureteric calculus and cholelitheasis. CT Abdomen done to confirm the diagnosis before undergoing lithotripsy, showed an incidental finding of osteochondroma arising from right pars interarticularis of L5 vertebra was observed. CT showed a well defined bony lesion protruding posteriorly from the right pars interarticularis of L5 vertebra (measuring ~ 1.4 x 1.1 cm) with continuity of cortex and medulla with the involved vertebra. Radiograph also showed a bony mass protruding posteriorly, probably arising from the L5 vertebra. Magnetic resonance imaging showed a bony outgrowth with fatty marrow seen arising from right pars interarticularis of L5 vertebra and pointing posteriorly. There was no large cartilage cap or soft tissue component. He underwent ureteric stenting for the calculi and was relieved of his symptoms. He was just reassured with respect to the spinal osteochondroma (Figure 1).
