We report a case of malignant peritoneal mesothelioma (MPM) in a 31-year-old male with history of cerebral palsy, hydrocephalus, and ventriculoperitoneal shunt (VPS) placed since infancy. He presented with fever, abdominal pain and distension. Computed tomography scan revealed a thick-walled rim-enhancing fluid collection, interpreted as pseudocyst. Intraoperatively, diffuse nodular peritoneal thickening with adhesions was demonstrated. The resection specimen consisted of multiple membranous fragments displaying firm nodules. Microscopic examination revealed a tumefactive malignant-appearing epithelioid proliferation involving the peritoneum, focally invading the underlying fat. Immunohistochemically, the tumor cells expressed keratin AE1/AE3, CK7, CK5/6, Calretinin, WT1 and D2-40, and were negative for CEA and MOC31. The findings were consistent with MPM, epithelioid type. The patient’s condition continued to decline with increasing abdominal distension during the month following the original diagnosis. While atypical mesothelial hyperplasia has been described in association with long standing VPS, well-documented cases of MPM have not been previously reported in such context.

Amoebic colitis, caused by ingestion of water or food contaminated with the protozoan Entamoeba histolytica, can progress to a fulminant colitis. Computed tomography (CT) findings reported in the literature on this type of colitis are sparse. We present a 59-year-old male patient with a one-week history of progressive abdominal pain, abdominal distension and associated watery and bloody diarrhoea. A CT scan revealed deep ulcerations with submucosal and intramural tracking of contrast. Colonoscopy and biopsy confirmed a diagnosis of Amoebic colitis. The patient required a laparotomy and demised. Deep ulcerations with submucosal and intramural tracking of contrast on CT are diagnostic of fulminant amoebic colitis. Although not demonstrated at CT in this case, discontinuous bowel necrosis, omental wrapping (seen at laparotomy in our case) and neovascularisation of the bowel wall may be other features to look out for.

Abstract Background Excessive dynamic airway collapse (EDAC) is an uncommon cause of high airway pressure during mechanical ventilation. However, EDAC is not widely recognized by anesthesiologists, and therefore, it is often misdiagnosed as asthma. Case presentation A 70-year-old woman with a history of asthma received anesthesia with sevoflurane for a laparotomic cholecystectomy. Under general anesthesia, she developed wheezing, high inspiratory pressure, and a shark-fin waveform on capnography, which was interpreted as an asthma attack. However, treatment with a bronchodilator was ineffective. Bronchoscopy revealed the collapse of the trachea and main bronchi upon expiration. We reviewed the preoperative computed tomography scan and saw bulging of the posterior membrane into the airway lumen, leading to a diagnosis of EDAC. Conclusions Although both EDAC and bronchospasm present as similar symptoms, the treatments are different. Bronchoscopy proved useful for distinguishing between these two entities. Positive end-expiratory pressure should be applied and bronchodilators avoided in EDAC.

In this work, we discovered a new phenomenon—asymptomatic COVID-19 infection, or covert case, during the pandemic. All the 3 patients had a history of exposure, with no symptoms, and no abnormalities were found in computed tomography scan or lab tests. Except for case 2, the other patients’ severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) nucleic acid tests were negative. But their anti-SARS-COV-2 nucleocapsid antibody showed a dynamic trend, consistent with the process of virus infection and clearance. A growing number of asymptomatic or covert cases need more attention. Lack of surveillance may lead to another outbreak. We hope to demonstrate our cases to attract the attention of governments or health authorities that covert cases should be the focus as well.

Gallbladder perforation still continues to perplex surgeons; 25 such patients diagnosed either pre- or intra-operatively and managed at our institute over the last 10 years period were analysed. Only eight were diagnosed pre-operatively, while a large majority (17) had a wrong initial working diagnosis. Symptoms and signs were variable. No blood investigation was specific. A computed tomography scan was generally better than ultrasound in detecting the perforation. All our cases were managed operatively with no mortality and a mean duration of hospital stay of 6.8 days. Most perforations were extra-hepatic (84%) and those of Niemeier’s type I (52.2%). Because of its varied clinical presentation, gallbladder perforation is often an intra-operative diagnosis, but early intervention carries a good outcome.

A 1.5-y-old spayed female Juliana pot-bellied pig was presented to the Purdue University Veterinary Teaching Hospital with a history of wasting and anorexia. Enlarged and partially mineralized lymph nodes were identified on radiographs and computed tomography scan. Generalized lymphadenomegaly and disseminated nodules in the lungs, liver, spleen, and kidneys were identified on postmortem examination. Histologic examination revealed caseonecrotic granulomas with numerous intracellular, acid-fast bacilli. Mycobacterium kansasii type II was identified as the etiologic agent by PCR amplification using universal Mycobacterium primers, direct sequencing of the PCR amplicon, and comparison to sequences in GenBank. We describe a case in a pot-bellied pig of mycobacteriosis caused by an atypical mycobacterial species and highlight the important role of laboratory testing in suspected cases of tuberculosis.

Malignant peritoneal mesothelioma (MPeM) is a highly malignant neoplasm of the peritoneum, which carries a poor prognosis. A 70-year-old man, who was employed in the shipbuilding industry and exposed to asbestos for 50 years, was found to have a low-density lesion in the peritoneum around the liver and spleen, associated with multiple mediastinal and parasternal lymphadenopathy. Laparoscopic exploration was performed, and biopsy specimen analysis led to a diagnosis of MPeM. Initial systemic chemotherapy comprising cisplatin and pemetrexed yielded a modest cytoreductive effect. However, 4 months later, the patient presented with abdominal distension and anorexia. CT images revealed massive ascites, bowel obstruction and an enlarged intra-abdominal tumour, which was considered progression of the MPeM. The patient was treated with nivolumab. Bowel obstruction was improved after the first administration, and his sense of abdomen distension completely disappeared after the third administration. This case supports the utility of immunotherapy in MPeM.

Primary tracheal synovial sarcoma is a rare malignancy and is usually found incidentally. Tumours can present with cough, dyspnoea, stridor and intermittent haemoptysis. The diagnosis is challenging because it is rare, and the symptoms may mimic other diseases of airway obstruction. A previously well 53-year-old man presented with an eight-month history of cough. He had a history of minimal haemoptysis a few months prior to presentation. Spirometry showed an obstructive pattern, and a computed tomography scan of the thorax revealed an intraluminal tracheal mass. This case highlights that a thorough initial evaluation, including spirometry, leads to an earlier diagnosis and successful treatment of this rare sarcoma.

Non-traumatic subarachnoid haemorrhage (ntSAH) is a neurological emergency. Clinical presentation is usually with severe headache, with or without abnormal neurological signs on clinical examination. NtSAH affects both males and females from 30 to 70 years, and the incidence increases with age. The incidence varies widely around the world. The gender distribution also varies in different countries, although overall the incidence is higher in women than in men. The commonest cause is rupture of an intracranial aneurysm, accounting for around 80% of cases. Diagnosis is usually by finding blood in the classical subarachnoid distribution on a cranial computed tomography scan. A number of grading systems are used to classify ntSAH.
