The simultaneous occurrence of a gastrointestinal stromal tumor (GIST) and a gastric adenocarcinoma is uncommon, and has rarely been reported in the literature. The present report describes the case of a 74-year-old male patient who initially presented with an adenocarcinoma that had invaded the antral mucosa. Computed tomography then revealed the presence of a suspected GIST, in the form of a $2{\times}2$ cm mass at the hilum of the spleen. In view of the advanced age of the patient, a surgical approach that would minimize risk and maximize quality of life was preferred. The patient therefore underwent simultaneous laparoscopy-assisted distal gastrectomy for the adenocarcinoma and wedge resection for the GIST. This approach was only chosen after confirming that it would be possible to preserve three or more of the short gastric arteries that supply the area below the wedge resection site. This may be considered a feasible apapproach to the management of the simultaneous occurrence of a mid-to-low gastric body adenocarcinoma and a high gastric body GIST.

Traumatic carotid-cavernous fistula is a rare complication of moderate to severe head injury. For the treatment of carotid-cavernous fistula, detachable balloon occlusion is the best method of choice. A 26 year old male patient was hurt with a left periorbital penetrating injury 20 years ago, and then left side exophthalmos, bruit and right hemiparesis developed 10 years later. We experienced the very rare case of direct carotidcavernous fistula with cavernous dural arteriovenous fistula. Brain MRIs and cerebral angiograms revealed that direct carotid-cavernous fistula was accompanied by cavernous dural arteriovenous fistula due to longstanding venous hypertension and development of collateral circulation. Detachable balloon occlusion and surgical internal carotid artery ligation were not enough to occlude fistular flow, so cavernous dural arteriovenous fistula embolization was necessary. The authors present a case of long-standing traumatic carotid-cavernous fistula with cavernous dural arteriovenous fistula, with review of the literature.

Delayed cerebral infarction after resection of craniopharyngioma is a uncommon entity, but leads to high morbidity and mortality. We present 3 such cases and discuss the etiology and pathogenesis with review of pertinent literatures. In our cases, delayed deterioration of consciousness was observed in all cases. All of them expired. The cause may be multifactorial and the surgical approach may contribute to the pathogenesis of delayed cerebral infarction. We suspect vasospasm might be the major mechanism of pathogenesis. Vessels were primed to spasm during operation due to blood in the cistern or mechanical injury. Vasoactive materials may have been liberated from the pituitary stalk or injured hypothalamus, either at the time of surgery, or later, after portions of tumor have undergone necrosis. The high degree of suspicion to detect vasospasm should be done in the case of the delayed deterioration of mental status at an early stage of craniopharyngioma surgery. Possible mechanism underlying this delayed cerebral infarction are discussed.

Arachnoid cysts (AC) are intraarachnoidal cerebrospinal fluid collections, and account for 1% of all intracranial space-occupying lesions. Intracystic hemorrhage of the AC can occur spontaneously, but this is an extremely rare event. Herein, we present a case of hemorrhagic AC in a nontraumatic patient in the left middle cranial fossa. We also performed relevant literature review on this disease.

Noninfectious aortitis, inflammatory abdominal periaortitis, and idiopathic retroperitoneal fibrosis are chronic inflammatory diseases with unclear causes. Recent studies have shown that some cases of aortitis are associated with immunoglobulin G4 (IgG4)-related systemic disease. Herein, we report a case of IgG4-related aortitis (IgG4-RA) that was diagnosed after surgery. Our patient was a 46-year-old man who had experienced abdominal pain for several weeks. Preoperative evaluations revealed an area of aortitis on the infrarenal aorta. He underwent surgery, and histological examination resulted in a diagnosis of IgG4-RA.

A cardiac calcified amorphous tumor (CAT) is a rare non-neoplastic mass of the heart with histological characteristics comprising calcification and amorphous fibrous material. Little is known regarding the incidence, symptoms, and therapeutic strategies for CAT. Echocardiography and computed tomography were performed on a 48-year-old man who had a cardiac mass that was accidentally discovered on admission to a local hospital for a fracture related to a trauma that occurred 1 month prior. After surgery, a histological examination resulted in the diagnosis of a cardiac CAT. The patient was discharged without postoperative complications on the 12th day after surgery.

Purpose: To investigate the differences in clinical features and laboratory findings between group D and non-group D non-typhoidal Salmonella (NTS) gastroenteritis in children. Methods: A retrospective chart review of children diagnosed with NTS confirmed by culture study was performed. The clinical features and laboratory findings of group D and non-group D NTS were compared. Results: From 2003 to 2012, 75 cases were diagnosed as NTS at our center. The number of group D and non-group D patients was 45 and 30, respectively. The mean age was higher in group D than in non-group D patients (5.1 years vs. 3.4 years, p=0.038). Headaches were more frequently observed (p=0.046) and hematochezia was less frequently observed (p=0.017) in group D than in non-group D NTS gastroenteritis patients. A positive Widal test result was observed in 53.3% of group D and 6.7% of non-group D NTS cases (O-titer, p=0.030; H-titer, p=0.039). There were no differences in white blood cell counts, level of C-reactive protein and rate of antimicrobial resistance between group D and non-group D cases. Conclusion: The more severe clinical features such as headache, fever, and higher Widal titers were found to be indicative of group D NTS gastroenteritis. Additionally, group D NTS gastroenteritis was more commonly found in older patients. Therefore, old age, fever, headache, and a positive Widal test are more indicative of group D NTS than non-group D NTS gastroenteritis. Pathophysiological mechanisms may differ across serologic groups.
