No significant hilar or mediastinal widening is seen. The differential diagnosis for a single pulmonary mass includes primary or secondary carcinoma, hamartoma (especially if fat and calcification can be identified), pneumonia or arteriovenous malformation. The patient’s age, smoking history and chronic cough are red flags for considering carcinoma. The next step is rapid referral of the patient to chest clinic with a preceding staging computed tomography (CT) scan. Most hospitals have a streamlined process for the radiology department to flag up the patient to the relevant specialist clinic if cancer is suspected, in anticipation of an urgent general practitioner (GP) referral.
Plain radiographs complement this view by demonstrating the bone structure but with very poor soft tissue detail. Ultrasound is the investigation of choice in infants with unossified femoral heads but as the ossification centre develops and blocks the ultrasound from about 6 months onwards, radiographs are more useful. 2 shows the hip radiograph at 4 months. The aim is to diagnose a hip abnormality as soon as possible to minimize the degree of intervention required to fix the problem. Treatment ranges from observing (if very mild and picked up on a neonatal scan) to braces or surgical intervention.
Screening is done on infants with risk factors that include family history, breech presentation, foot deformities or neuromuscular disorders. Examination features that raise suspicion for hip abnormality include asymmetric groin creases, a click on movement and a click or subluxation on provocation tests. As with all ultrasound, gel is used to couple the ultrasound beam into the soft tissue and allow movement of the probe without loss of image. The baby is placed in the lateral position with the hip flexed and the probe is placed parallel to the ilium (bright line on the left of the image) and the orientation optimized to produce a horizontal image like a golf ball (stippled cartilage of the femoral head) on a tee (cup is the acetebulum, stalk is the ilium).
