A 16-year-old spayed female American Shorthair cat was presented with lethargy, anorexia, and wamble. Physical and blood examination did not reveal any remarkable findings. Abdominal ultrasonography identified the presence of a localized anechoic structure with a thick wall in contact with the small intestine and adjacent to the liver. Ultrasound-guided fine-needle aspiration of the structure revealed fluid containing numerous cocci and neutrophils. Two days after antibiotic treatment, exploratory laparotomy was performed and the content of the structure was removed before multiple lavages...

Multicystic peritoneal mesothelioma (MCPM) is a rare neoplasm, predominantly affecting female patients during their reproductive years. The lesion is usually distributed diffusely in the abdomen and pelvis, but the peritoneum of the pelvic organs is the most common site. MCPM is composed of fluid-filled translucent cysts, connected by varying amounts of fibrous tissue, and lined by a layer of mesothelial cells. Because of the rarity of this disease, the pathogenesis and natural history of MCPM remain poorly understood and continuously debated...

OBJECTIVE/BACKGROUND: Epidemiological screening studies have demonstrated that the prevalence of abdominal aortic aneurysm (AAA) of Asian origin appears to be low and so increases uncertainty about the cost effectiveness of screening for AAAs in Chinese people. Some studies have demonstrated a higher prevalence of AAA in patients with atherosclerotic risk factors. The purpose of the study was to determine the prevalence of AAA and to explore the high risk group of AAA in Chinese patients with atherosclerotic risk factors...

Serous cystadenomas of pancreas are unusual cystic tumour. The microcystic forms is more common and its radiological diagnosis is easy. However, the macrocystic unilocular form of serous cystadenoma can be mistaken with other malignant macrocystic lesions of the pancreas. We report the case of a 17 year-old girl, admitted to the National Hospital of Niamey (Niger), with abdominal pain and an unilocular macrocystic serous cystadenoma of pancreas, diagnosed after histological examination of the surgical specimen...

AIM: To investigate the association between a recent gastrointestinal (GI) endoscopy and the subsequent risk of pyogenic liver abscess (PLA). METHODS: We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were selected as reference controls. We identified and compared the possible risk factors for PLA and GI endoscopies performed before the index date (when PLA was diagnosed) between the two cohorts...

BACKGROUND: High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics...

A 67-year-old man presented with fever, night sweat and abdominal complaints for about 4 weeks. Ultrasound and a computed tomography scan showed distinct ascites as the main finding, presenting as exsudate with predominating lymphoid cells. Because of long-term immunosuppressive therapy with the tumor necrosis factor (TNF)-α inhibitor golimumab for psoriasis, the suspicion for a possible tuberculous peritonitis arose. This was confirmed with an enzyme-linked immunospot assay, a high level of adenosine deaminase in the ascites and a peritoneum which was studded with multiple whitish nodules, corresponding to granulomas with giant cells...

Endoscopic ultrasound (EUS) has been increasingly used for the diagnosis and staging of pancreatic cancer. It has recently become the modality of choice in assessing pancreatic lesions overcoming other traditional modalities. Typically lesions located at the tail of the pancreas are best accessed through the stomach. We present a patient with pancreatic tail mass occurring in the setting of a large hiatal hernia, intrathoracic stomach, and severe lumbar levoscoliosis. Due to altered anatomy and extensive vascular connections of the mass, any surgical or radiological intervention was considered high risk for the patient...

The authors present a case of a pneumatocele associated with blunt trauma in a child. An 11-year-old boy was admitted to the emergency department after he was knocked over and his chest was trapped under a soccer goal. Chest computed tomography (CT) revealed several cavities in the lobes of both lungs. The CT of the abdomen revealed traumatic laceration of the liver. The patient was treated conservatively. His condition was stable and subsequently improved. He was discharged 19 days later. After nine months, a chest radiograph showed complete resolution of the pneumatocele, and abdominal ultrasound demonstrated complete resolution of the liver hematoma...

A 45-year-old woman was found to have a pancreatic tumor by abdominal ultrasound performed for a medical check-up. Abdominal contrast-enhanced computed tomography showed a hypovascular tumor measuring 30 mm in diameter in the pancreatic tail. Endoscopic ultrasound-guided fine needle aspiration was performed. An extragastric growing gastrointestinal stromal tumor was thereby diagnosed preoperatively, and surgical resection was planned. Laparoscopic surgery was attempted but conversion to open surgery was necessitated by extensive adhesions, and distal pancreatectomy, splenectomy, and partial gastrectomy were performed...

The quadratus lumborum (QL) block facilitates the administration of anaesthesia to the anterior abdominal wall. The use of ultrasound (US) improves the accuracy of the QL block and reduces the risk of adverse events. Electromyography (EMG) in combination with US for muscle plane blocks has not been described previously. We postulated that the addition of EMG-guided needle positioning might assist the execution of this block. This case report describes the first use of combined needle EMG and US to carry out a QL block performed for postoperative analgesia following an open appendicectomy...
