The scapula ossifies from multiple ossification centres, with ossification in the scapular body seen at the time of birth. Ossicle inferior angle of the scapula (OIAS) is an anatomical anomaly resulting from non-fusion of the ossification centre of the inferior angle of the scapula. OIAS remains asymptomatic and is infrequently detected as a palpable and painful abnormality, leading to patient discomfort and a need for healthcare assistance. OIAS can be detected on radiography, with Computed Tomography (CT) reserved for cases with an alternative diagnosis, like in our case. A 14-year-old female patient presented with a palpable and occasionally painful bony hard swelling at the level of the anterolateral aspect of the right 5th and 6th ribs, confirmed to be OIAS on CT chest. The patient was assured of its benign nature and received no further management. OIAS is an anatomical variation to be kept in mind whenever a palpable bony hard abnormality is encountered around the inferior angle of the scapula, avoiding unnecessary medical and/or surgical management and patient apprehension.
