In areas where there is a weakness or natural opening in the abdominal wall, the abdomen's internal contents can push through, and that is what is called a hernia. - Tends to occur within 6 inches above imaginary line connecting both anterior superior iliac spines. Incisional hernias are relatively common because surgical incisions weaken the abdominal area. They are distinguished primarily based on location and content. Lumbar hernias occur through defects in the lumbar muscles or the posterior fascia, below the 12 th rib and above the iliac crest. However, post- Different imaging modalities can be useful in identification of thoracic hernias, . Abdominal wall hernias can extend above the level of the diaphragm through the superficial or deep layers of the thorax and present as a superficial chest wall hernia. Complications predominantly relate to bowel incarceration, strangulation, and intestinal obstruction. When large, hernias diminish quality of life. Imaging thoracic hernias.

Radiology Cases of Abdominal Wall Hernia Transverse US of the midline abdominal wall just superior to the umbilicus shows echogenic omental fat herniating in the midline between the medial rectus muscles which are abnormally displaced to the lateral aspect of the image and which should normally be joined together in the midline. However, imaging of the abdominal wall is commonly valuable to both quantify the magnitude of RD, its precise extent in relationship to fixed abdominal landmarks, evaluate for co-existent abdominal wall hernia, and assess the remainder of the abdominal wall in preparation for any proposed treatment. Computed tomography clearly . At our institution, ultrasound guided botox injection of the lateral abdominal wall muscles is commonly performed 3-4 weeks prior to the date of surgery for ventral hernia repair (Figure 3). 2 Incisional hernias occur after laparotomy and can occur in 11% to 23% of patients, depending on suturing techniques used. The anterior abdominal wall, which is composed of three layers (skin and adipose tissues; the myofascial layer; and the deep layer, consisting of the transversalis fascia, preperitoneal fat, and the parietal peritoneum), has many functions: containment, support and protection for the intraperitoneal contents, and involvement in movement and breathing.

Abdominal wall hernias account for most external hernias [1-3].Diagnosis is usually made at physical examination; however, clinical diagnosis can be difficult, especially in patients with obesity, pain, or abdominal wall scarring [].In these cases, abdominal imaging may be the first clue to the correct diagnosis. The patient's clinical history, however, may be atypical and the physical examination may be limited in obese patients, in patients with severe abdominal pain and distention, and in patients with small hernias or with hernias located in uncommon sites [1,2,3,4,5 . Abdominal muscular anatomy on computed tomography (CT) in a patient with ventral hernia is shown in Figure 2. Because of the risk of developing complications, most abdominal wall hernias are surgically repaired, even if asymptomatic. Widening or dehiscence of the scar allows intra-abdominal contents to herniate into the subcutaneous tissues. This section of transversalis fascia is known as spigelian fascia. CME (0) Ultrasound.
