The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen. There was no nausea or vomiting and bowel movements were normal. She lost 10 kg during the 3 mo before presentation. The patient had undergone an appendectomy 12 years previously. Physical examination revealed a tender mass, 10 cm in diameter, under the appendectomy scar. The preoperative laboratory findings, tumor markers and plain abdominal radiographs were normal. Multi-slice computed tomography scanning showed an inhomo-genous abdominal mass with minimal vascularization in the right lower abdomen 8.6cm×8cm×9 cm in size which communicated with the abdominal wall. The abdominal wall was thickened, weak and bulging. The abdominal wall mass did not communicate with the cecum or the ascending colon. Complete excision of the abdominal wall mass was performed via median laparotomy. Histopathological examination revealed a granuloma with a central abscess. This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options.展开更多

Methods BALB/c mice were immunized with SDS-PAGE purified major outer membrane protein (MOMP) from CT and the monoclonal antibodies were obtained subsequently. Two-site ELISA was developed to detect CT infection. Results: The established assay was able to detect as low as 1.248ug/ml MOMP with interrun and inrun CV 6.9% and 3.1% respectively. 94% (34/36) of culture-positive samples were found to be positive in the current examination, indicating the high sensitivity of this assay. Conclusion: The assay is applicable for clinical diagnosis of CT infection.展开更多
