A gastric schwannoma is a rare primary spindle cell mesenchymal tumor of the digestive tract. Gastric schwannomas originate from Schwann cells of the peripheral nerves in the stomach. The majority of schwannomas are benign, slow growing tumors only a few of which develop into malignancies. Due to their indolent course, in most cases, gastric schwannomas are asymptomatic or discovered as an incidental finding on cross-sectional imaging or endoscopy. When symptomatic, the most common presenting symptoms are abdominal pain, upper gastrointestinal bleeding and intra- abdominal mass. Preoperatively, gastric schwannomas are difficult to differentiate from other mesenchymal tumors, such as gastrointestinal stroma or leiomyoma which develop from mesenchymal stem cells. The optimal management of the tumor is based on the symptoms of the patient, tumor size and histologic grading and the prognosis is excellent after complete surgical or endoscopic removal. Gastric schwannomas need multidisciplinary team management for definitive diagnosis and management, including specialists from gastroenterology, surgery, radiology and pathology.

Slow Growing

Schwannomas are generally slow growing asymptomatic neoplasms that rarely occur in the GI tract. However, if found, the most common site is the stomach. Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract, and 60–70% of them occur in the stomach. Owing to their typical presentation as submucosal neoplasms, gastric schwannomas and GISTs appear grossly similar. Accordingly, the differential diagnosis for a gastric submucosal mass should include gastric schwannomas. Furthermore, GI schwannomas are benign neoplasms with excellent prognosis after surgical resection, whereas 10–30% of GISTs have malignant behavior. Hence, it is important to distinguish gastric schwannomas from GISTs to make an accurate diagnosis to optimally guide treatment options. Nevertheless, owing to the paucity of gastric schwannomas, the index of suspicion for this diagnosis is low. We report a rare case of gastric schwannoma in 53-year-old woman who underwent laparoscopic partial gastrectomy under the suspicion of a GIST preoperatively but confirmed to have a gastric schwannoma postoperatively. This case underscores the importance of including gastric schwannomas in the differential diagnosis when preoperative imaging studies reveal a submucosal, exophytic gastric mass. For a gastric schwannoma, complete margin negative surgical resection is the curative treatment of choice.

Abnormal communications between the systemic and pulmonary venous systems are rare but can present as a opacity on chest radiograph. A solitary vessel communicating as a fistula directly between the systemic arterial circulation and the pulmonary venous system is not widely described. These may have significant implications in the long-term cardiovascular health of an individual acting as a left to right shunt. There is no clear consensus as to the management, but surgical management and endovascular embolisation have been successfully used. We present a case where a systemic arteriaopulmonary fistula originating from the abdominal aorta and connecting to the right inferior pulmonary vein manifested as an incidental finding on a chest radiograph and was further evaluated on cross-sectional imaging in a young patient. Chest radiographs are non-specific and it is important to be aware of the less frequent but important pathologies that can be picked up on plain chest radiographs, which inturn should warrant further investigation. This is presented in conjunction with a review of the available literature along with a discussion regarding the differential diagnosis and management applicable to the general clinician.

De Garengeot Hernia

The de Garengeot hernia is an uncommon and potentially confounding pathologic process in which the appendix is contained within a femoral hernia. While typically a benign incidental finding, superimposed acute appendicitis is a rare but serious complication. Identification of this entity is crucial to patient management and ultimately outcome with imaging playing a critical role. Cross-sectional imaging, with either CT or MRI, should be performed in all cases of suspected incarcerated de Garengeot hernia to facilitate the appropriate diagnosis and surgical intervention. Herein, we present the fifth case of a prospective CT diagnosis of the de Garengeot hernia in a 61-year-old female who presented with an irreducible right femoral hernia. The patient underwent CT examination which demonstrated the appendix within the femoral hernia sac with an associated periappendiceal fluid collection. The patient was taken for emergent surgical intervention at which time the appendix was found within the hernia sac. The appendix was removed, the defect repaired, and ultimately the patient recovered well.

Pancreatic cysts are common, affecting up to 10% of the general population. Widespread use of abdominal cross-sectional imaging has increasingly identified asymptomatic patients with "incidental" pancreatic cysts. Our understanding of common pancreatic cysts has improved; however, the ideal management of patients with pancreatic cysts (particularly those with malignant potential) has not been standardized. This review discusses the clinical approach to patients with pancreatic cysts, with particular attention to those with "premalignant" cysts such as intraductal papillary mucinous neoplasms (IPMNs). This review contains 17 figures, 13 tables, and 42 references.

Abstract We present a case of antenatally detected abdominal mass and an alternative diagnostic course for suspected neonatal neuroblastoma as a result of investigative findings. A female infant presented antenatally with a left upper quadrant mass initially managed as a suspected neonatal neuroblastoma; further cross-sectional imaging suggested a wider differential including teratoma and aided surgical planning. The multi-disciplinary team (MDT) decision was for an early excision at 31 days and post-operative histology identified a diagnosis of fetus-in-fetu (FIF). We describe this case as a compliment to the current literature and an example of a necessary variation to recognised diagnostic and treatment pathways as a result of investigative findings.

Uncommon Condition

Posterior rectus sheath hernia is a truly rare finding, with only 11 documented cases since the first report in 1937. A posterior rectus sheath hernia is herniation of bowel and/or omentum through the posterior portion of the rectus sheath, but not through any other structure. This can only occur medial to the spigelian fascia, differentiating it from a spigelian hernia. Previous missed cases have led to complications such as bowel incarceration, obstruction or even strangulation and have required surgical intervention. In this case report, we describe an incidental finding of a non-complicated posterior rectus sheath hernia in an 83-year-old male. Annotated cross-sectional imaging provides anatomical context that is not widely available in the existing literature. Due to its rarity and potential complications, it is also important to report this case in order to enhance the evidence base for posterior rectus sheath hernia and to familiarize this uncommon condition to radiologists, clinicians and surgeons.

Sectional Imaging

The evaluation of pulmonary veins during cross-sectional imaging of the chest and the knowledge of their embryology and anatomy are useful for detecting congenital conditions that may be clinically significant. Moreover, with the spread of cross-sectional imaging it is very frequent to find anatomical variants; therefore the radiologist should easily recognize their appearances. This case report shows a left-side upper partial anomalous pulmonary venous return (PAPVR) through a “curved” vein that joins the left brachiocephalic vein, in a female patient who underwent whole-body computed tomography (CT) for staging endometrial cancer. This was an incidental finding, not related to any symptoms; however, we explain the anatomical aspects of this abnormality within the congenital condition of PAPVR and its possible clinical relevance.
