1/33. Descending mesocolon defect herniation: case report.Internal hernia, herniation of the internal organs through defects in the intraabdominal cavity, is rare. Due to the rarity of this pathology and lack of the specific symptoms and signs, early diagnosis and treatment are always stressful to the clinician and misdiagnoses may occur in the emergency room. The prognosis of a patient with uncomplicated internal hernia is excellent. We report a 21-year-old Chinese man with internal herniation through a defect of mesocolon, presented as an impalpable abdominal mass which was shown only on imaging studies. In addition to the typical whirlpool pattern, a huge solid mass between the pancreatic tail and stomach was found under computed tomography (CT) scan. The major symptoms were intermittent epigastralgia and abdominal fullness that had bothered him for years. physical examination results showed only mild epigastric tenderness. Computed tomography scans and exploratory laparotomy of the abdomen played vital roles during diagnosis. The herniated organ was a portion of jejunum with partial small intestinal obstruction.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/33. Traumatic cardiac herniation diagnosed by echocardiography and chest CT scanning: report of a case.A 62-year-old man who had suffered fractures of the left chest wall and hemothorax 1 year earlier was admitted to our hospital with multiple injuries as a result of a traffic accident. Chest drainage was immediately performed under the diagnosis of left hemothorax followed by immobilization of fractures of the femur and radius. On the second day after admission, he suddenly developed severe chest pain and dyspnea after sitting up in bed. echocardiography and chest computed tomography (CT) showed herniation of the left ventricle into the left thoracic cavity, whereby a diagnosis of cardiac herniation due to rupture of the pericardium was made and an emergency surgical repair was successfully performed. Only eight cases of patients surviving after traumatic cardiac herniation have been reported in japan; however, this is the first in which a preoperative diagnosis was made by echocardiography and chest CT scanning prior to surgical repair.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
3/33. Traumatic herniation of the heart into the right hemithorax.Pericardial rupture after blunt chest trauma is described in the literature. This case report summarises our experience with a 22-year old male patient who suffered blunt chest trauma during a motor vehicle accident. On admission no serious injuries could be detected, but 3 hours later, displacement of the heart to the right hemithorax combined with sudden cardiac failure appeared. Emergency thoracotomy revealed a right-sided rupture of the pericardium with complete herniation of the heart into the right pleural cavity and consequent strangulation by the margins of the pericardial defect.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
4/33. Thoracic idiopathic spinal cord herniation at the vertebral body level: a subgroup with a poor prognosis? case reports and review of the literature.The authors present two cases of thoracic idiopathic spinal cord herniation (TISCH) occurring at the vertebral body (VB) level in whom adequate surgical reduction failed to reverse symptoms. In the second case, in which TISCH occurred into a VB cavity, presentation was atypical (subacute spinal cord syndrome) and there was persistent postoperative deterioration. In both cases, adequate surgical reduction was achieved via a posterior midthoracic laminectomy, and reduction was maintained by closure of the anterior dural defect by using prosthetic material. Thoracic idiopathic spinal cord herniation occurring at a VB level may be technically well treated by surgical reduction, but the outcome appears less predictable. Herniation that occurs directly into a VB cavity may form a distinct subgroup in which the presentation is atypical and the prognosis worse.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
5/33. Herniation of the heart into the right pleura following blunt chest trauma--an unusual presentation.A 21-year-old male patient had sustained a blunt chest and abdominal trauma during a traffic accident. All the major injuries were on the left side. On the second day, a massive shift of the mediastinum to the right was noted. Further investigations raised the suspicion of herniation of the heart into the right pleural cavity. However, the patient's hemodynamic stability did not fit into the picture. echocardiography and CT scan helped reinforce our suspicion. Herniation was confirmed at the operation, which was performed through median sternotomy. The patient recovered well without complications.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
6/33. Laparoscopic repair of a right paraduodenal hernia.BACKGROUND: Laparoscopic repair of a right paraduodenal hernia has never been described in the literature. A 24-year-old woman was admitted after 2 weeks of intermittent abdominal pain associated with nausea and vomiting. physical examination was normal. Laboratory studies and upper endoscopy were normal. Computed tomography revealed that the small bowel was on the right side of the abdomen and the colon on the left, suspicious for malrotation. Subsequent upper gastrointestinal series with small bowel follow-through revealed the ligament of Treitz on the right with the small bowel encased within a probable hernia sac. A presumptive diagnosis of a right paraduodenal hernia was made. methods AND RESULTS: Initial access was obtained with a 10-mm infraumbilical port followed by placement of 5-mm ports in the right and left upper and lower quadrants. The duodenum was identified and the small bowel was found encased within a hernia sac, which was opened widely from the duodenum to the pelvis. The hernia sac was opened laterally to avoid injury to the superior mesenteric vessels. The small bowel was then released from the sac into the peritoneal cavity. The entire bowel was inspected and no other abnormalities were noted. The patient had resolution of her abdominal pain and her postoperative course was uncomplicated. She was discharged home on postoperative day 3 and has since done exceptionally well. CONCLUSIONS: Paraduodenal hernia, a rare cause of small bowel obstruction, can present a diagnostic challenge. However, when the diagnosis is made preoperatively, a laparoscopic repair is a feasible and practical option.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
7/33. Herniation of the buccal fat pad into the oral cavity: a case report.An interesting lesion is presented, wherein a tiny traumatic perforation of the buccal mucosa and buccinator muscle forced a large portion of the buccal fat pad to extrude into the oral cavity. Such a situation can alarm any clinician & reinforces the importance of careful history taking and thorough examination, before treating patients.- - - - - - - - - - ranking = 13.090358335957keywords = oral cavity, cavity (Clic here for more details about this article) |
8/33. Ileal herniation into a sigmoid colon epiploic fat foramen extrasigmoid hernia.Internal abdominal hernia (IAH) is defined as protrusion of viscus through a peritoneal or mesenteric aperture, leading to its encapsulation within another compartment in the abdominal cavity. Herein we report a rare case of small bowel obstruction due to herniation with incarceration of a loop of ileum into a foramen formed by the epiploic fat of the sigmoid colon due to a non-specific inflammatory process; this may be defined as extrasigmoid hernia. To our knowledge, there has been no previous report of this type of IAH in the English literature. In summary, an acute intestinal obstruction with strangulation in the absence of an external hernia without previous operation suggests the possibility of internal hernia, especially if the patient has a history of intermittent abdominal distress.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/33. Functional MR imaging of submandibular herniation of sublingual tissues through a gap of the mylohyoid muscle in two cases of submandibular "masses".Except for neoplasms, in symptomatic patients with submandibular swellings, gaps of the mylohyoid muscle may be the cause of herniations of sublingual tissues, such as fat and/or the sublingual gland. In two patients with a submandibular swelling, MRI with standard sequences including contrast enhancement was performed to exclude a neoplastic lesion. In addition, we performed a trueFISP sequence during modified Valsalva's maneuver. In both patients, a neoplasm was excluded. Instead, the trueFISP sequence during the modified Valsalva's maneuver showed submandibular herniation of sublingual tissues. If MRI of the floor of the mouth does not show a neoplasm, an additional functional MR investigation should be performed. Gaps of the mylohyoid muscle can be the cause of herniating sublingual tissues (similar to plunging ranulas). During the modified Valsalva's maneuver, sublingual fat and/or gland can herniate and cause a symptomatic submandibular swelling. A coronal trueFISP sequence is particularly suited to demonstrate this.- - - - - - - - - - ranking = 0.22482303001079keywords = mouth (Clic here for more details about this article) |
10/33. Mylohyoid herniation of the sublingual gland diagnosed by magnetic resonance imaging.Mylohyoid herniation of the sublingual gland has been a frequent finding at dissection of adult human cadavers and at retrospective studies of computed tomography (CT) and magnetic resonance imaging (MRI) of the floor of the mouth. Even so, very few clinical reports exist. The present report describes an adolescent boy with a suspected submental tumour, which at MRI was shown to be caused by a mylohyoid hernia of part of an enlarged, but otherwise normal sublingual gland.- - - - - - - - - - ranking = 0.22482303001079keywords = mouth (Clic here for more details about this article) |
