The diagnosis of<unk>  can be made clinically without any imaging. Typically, individuals with the syndrome will have an underlying condition such as scoliosis or osteoporosis in which may cause the<unk>  contact. The examiner will assess for the possibility of contact by noting the medical history and reported symptomology by the individual. The clinician will examine the individual for<unk>  contact within a standing position and in movement. Tenderness of the iliac crest and the lower ribs will be assessed with physical palpation. Usually, flexion of the trunk laterally can trigger pain on the affected side(s), which is useful in diagnosis to pinpoint the exact location of<unk>  contact. Though radiological imaging is not needed for<unk>  diagnosis, it is often uses to assess for underlying conditions and rule out differential diagnosis. Imaging such as the use of an x-ray can reveal irregularities of the surfaces of the lower ribs and iliac crest or abnormally long 12th ribs, which may give suspicion to the diagnosis of<unk> . Computed tomography (CT) scans can reveal kyphotic deformities, including a reduced distance between the lower ribs and the iliac crest, giving rise to the possibility of<unk>  contact. 270x270px Differential diagnosis Since<unk>  can present in pain in many areas surrounding the back, flank, and abdomen, the differential diagnosis for the condition can be extensive. Some of the diagnosis include but not limited to neuropathic pain of the intercostal nerves, conditions of the hip, pinched nerves within the spine, myofascial pain, and visceral causes. Differential diagnosis may also include an investigation into the pathology which caused the<unk>  contact if it is not previously known, such as undiagnosed scoliosis, back strain, osteoporosis, or a compression fracture.<unk>  should also be differentiated from other conditions affecting the lower ribs such as slipping rib syndrome, which is a condition that involves the increased mobility of the 8th to 10th ribs at their interchondral joints. Additionally, hypermobile 11th and 12th ribs may cause twelfth rib syndrome due to the floating ribs impinging on the intercostal nerves (intercostal neuralgia). Neither of these conditions involve the iliac crest.
