Plain radiograph of dorsal spine AP view revealed well-defined homogeneous opacity in left paraspinal region at D5/D6 level obliterating the left paraspinal line
and forming obtuse angle with the left lung parenchyma.
The absence of certain signs may help in excluding the diagnosis: loss of the aorticopulmonary window, abnormality of the aortic arch, rightward tracheal shift, and widening of the left paraspinal line
without associated fracture.
30) In routine practice, evaluation of chest and abdomen radiographs in children should include close inspection of the paraspinal lines
for widening or loss of definition, evaluation for rib destruction or intercostal space widening.
Furthermore, there was absence of the azygo-oesophageal line and bilateral paraspinal lines
Slightly overpenetrated films allow better visualisation of the thoracic spine, paraspinal lines
and aortic outline F Films for comparison Reviewing old films on the same patient may be helpful ABCDEF is a mnemonic to remember a systematic way of going through chest radiographs.
