Diaphragm eventration
 Incomplete muscularization of the diaphragm.
 This very common abnormality consists of a thin membranous sheet
replacing the diaphragmatic muscle.
 Usually it is partial, involving one half to one third of the hemidiaphragm,
frequently the anteromedial portion of the right hemidiaphragm.
 The lack of muscle is manifested on the chest radiograph by an elevation
of the affected portion of the diaphragm, usually depicted as a smooth
hump on the contour of the hemidiaphragm.
 When the entire hemidiaphragm is involved, it appears elevated and on
fluoroscopy, there is poor, or absent, paradoxical movement.
 In many cases, the distinction between this condition and acquired
paralysis of the phrenic nerve is impossible

Diaphragmatic paralysis
Diaphragmatic paralysis
 may be unilateral or bilateral. The most common cause of
unilateral paralysis of the diaphragm is involvement of the
phrenic nerve by a tumour. But there are many other
causes. It occasionally occurs as a complication of various
neurological diseases. Also injury to the phrenic nerve as a
result of trauma to the thoracic cage or cervical spine and
pressure upon the phrenic nerve from a substernal thyroid
or aortic aneurysm can cause paralysis. Infectious processes
involving the lung, pleura and/or mediastinum may result
in temporary or permanent diaphragmatic paralysis. Finally
diaphragmatic paralysis can be idiopathic.
Diaphragmatic paralysis
Diaphragmatic paralysis
 The radiological evaluation of diaphragmatic paralysis
requires chest radiographs, adequate fluoroscopic tests and
clinical information. In some cases chest ultrasonography can
also be useful for studying and monitoring diaphragmatic
movement.
 Four signs indicate diaphragmatic paralysis:
– elevation of the diaphragm above the normal range;
– diminished, absent or paradoxical movement on inspiration;
– mediastinal shift on inspiration; and
– paradoxical movement during sniffing (Fig.1).
Diaphragmatic paralysis
Diaphragmatic paralysis
 All these signs need not be present simultaneously but paradoxical
movement during sniffing is generally considered as the sine qua non
of diaphragmatic paralysis. However, these signs should be interpreted
with care since false positive and false negative results occur and other
diseases such as lung fibrosis, atelectasis, (hydro)pneumothorax,
bronchial stenosis, pneumonia, emphysema and diaphragmatic injury
can cause abnormal diaphragmatic position and motion. In addition,
the sniff test can be normal in apparently normal patients. Though in
these circumstances the paradoxal motion is small (< 2 cm) and
predominantly seen in the anterior part of the diaphragm. The
radiological diagnosis of bilateral diaphragmatic paralysis can be
difficult and the fluoroscopic study of bilateral diaphragmatic
paralysis requires simultaneous evaluation of diaphragmatic and chest
wall movement.

    Diaphragm eventration  Incompletemuscularization of the diaphragm.  This very common abnormality consists of a thin membranous sheet replacing the diaphragmatic muscle.  Usually it is partial, involving one half to one third of the hemidiaphragm, frequently the anteromedial portion of the right hemidiaphragm.  The lack of muscle is manifested on the chest radiograph by an elevation of the affected portion of the diaphragm, usually depicted as a smooth hump on the contour of the hemidiaphragm.  When the entire hemidiaphragm is involved, it appears elevated and on fluoroscopy, there is poor, or absent, paradoxical movement.  In many cases, the distinction between this condition and acquired paralysis of the phrenic nerve is impossible

    Diaphragmatic paralysis Diaphragmatic paralysis may be unilateral or bilateral. The most common cause of unilateral paralysis of the diaphragm is involvement of the phrenic nerve by a tumour. But there are many other causes. It occasionally occurs as a complication of various neurological diseases. Also injury to the phrenic nerve as a result of trauma to the thoracic cage or cervical spine and pressure upon the phrenic nerve from a substernal thyroid or aortic aneurysm can cause paralysis. Infectious processes involving the lung, pleura and/or mediastinum may result in temporary or permanent diaphragmatic paralysis. Finally diaphragmatic paralysis can be idiopathic.
  • 51.
    Diaphragmatic paralysis Diaphragmatic paralysis The radiological evaluation of diaphragmatic paralysis requires chest radiographs, adequate fluoroscopic tests and clinical information. In some cases chest ultrasonography can also be useful for studying and monitoring diaphragmatic movement.  Four signs indicate diaphragmatic paralysis: – elevation of the diaphragm above the normal range; – diminished, absent or paradoxical movement on inspiration; – mediastinal shift on inspiration; and – paradoxical movement during sniffing (Fig.1).
  • 52.
    Diaphragmatic paralysis Diaphragmatic paralysis All these signs need not be present simultaneously but paradoxical movement during sniffing is generally considered as the sine qua non of diaphragmatic paralysis. However, these signs should be interpreted with care since false positive and false negative results occur and other diseases such as lung fibrosis, atelectasis, (hydro)pneumothorax, bronchial stenosis, pneumonia, emphysema and diaphragmatic injury can cause abnormal diaphragmatic position and motion. In addition, the sniff test can be normal in apparently normal patients. Though in these circumstances the paradoxal motion is small (< 2 cm) and predominantly seen in the anterior part of the diaphragm. The radiological diagnosis of bilateral diaphragmatic paralysis can be difficult and the fluoroscopic study of bilateral diaphragmatic paralysis requires simultaneous evaluation of diaphragmatic and chest wall movement.

    Conclusions Conclusions  Diaphragmatic injuryafter penetrating thoracoabdominal Diaphragmatic injury after penetrating thoracoabdominal trauma can be clinically silent. However, the results of a trauma can be clinically silent. However, the results of a missed injury can be catastrophic. Clinical suspicion must be missed injury can be catastrophic. Clinical suspicion must be high. high.  Penetrating injuries with a Penetrating injuries with a trajectory trajectory below the mammary line below the mammary line and above the costal margin – particularly on the left – should and above the costal margin – particularly on the left – should arouse suspicion of a diaphragmatic injury arouse suspicion of a diaphragmatic injury  DPL is superior to imaging modalities in diagnosing DPL is superior to imaging modalities in diagnosing diaphragmatic trauma is nonetheless imperfect diaphragmatic trauma is nonetheless imperfect  Laparoscopy should be considered whenever diaphragmatic Laparoscopy should be considered whenever diaphragmatic injury is suspected, even if the remainder of the workup is injury is suspected, even if the remainder of the workup is negative negative
