A 71-year-old man undergoing hemodialysis (HD) was admitted to our hospital with congestive heart failure (CHF) and pneumonia. After admission, ultrafiltration with HD was urgently performed because of a lack of respiratory improvement despite the use of noninvasive positive pressure ventilation. During HD, cerebral regional saturation of oxygen (rSO2) was monitored by INVOS 5100c oxygen saturation monitor (Covidien Japan, Japan) to evaluate changes in tissue oxygenation. At HD initiation, cerebral rSO2 was very low at 34% under the fraction of inspiratory oxygen (FiO2) of 0.4. Ultrafiltration was performed at the rate of 0.5 L/h thereafter, cerebral rSO2 gradually improved even as inhaling oxygen concentration decreased. At the end of HD, cerebral rSO2 improved at 40% under a FiO2 of 0.28 as excess body fluid was removed. After pneumonia and CHF improved, he was discharged. Reports of the association between cerebral oxygenation and acute CHF status in patients undergoing HD are limited; therefore, in our experience with this case, cerebral oxygenation deteriorated with the CHF status but was improved by adequate body-fluid management during HD.

A 71-year-old woman presented to our hospital with fever and dyspnea. Computed tomography showed shadows of bilateral pneumonia and anterior vertebral mass. She was admitted to our hospital for respiratory failure. Despite treatment with antibiotics, she developed right thoracic empyema. A high level of inflammation and fever persisted, despite chest tube drainage and continued treatment with antibiotics. Therefore, thoracoscopic curettage was conducted. The histopathological findings of the curetted anterior vertebral body lesion revealed the diagnosis of chordoma. After confirming that all the culture results and inflammation findings had turned negative, the patient was discharged from the hospital. Thoracic vertebral chordoma is being treated at the department of orthopedics.

Patients with COVID-19 infection may present to the Emergency Department (ED) with gastrointestinal complaints and no respiratory symptoms. We are presenting 3 patients who came to the ED with abdominal pain; and the computed tomography [CT] of the abdomen showed findings suggestive of COVID-19 pneumonia. A 65-year-old male patient presented with symptoms of urinary tract infection and left renal angle tenderness. A 42-year-old male patient presented with right flank pain postextracorporeal shock wave lithotripsy. A 71-year-old male known to have type 2 diabetes mellitus and who had had whipple surgery for a neoplasm of the head of the pancreas presented with a painful epigasteric swelling. The 3 patients had positive COVID-19 polymerase chain reaction (PCR) tests and mild-to-moderate illness, and were discharged home after 2 weeks with a good recovery. The first patient had a false negative early PCR test, which turned positive on 2 repetitions of the test. A systematic review of CT abdomen, including inspection of the lung bases using the lung window in all CT abdomen, is essential to detect findings suggestive of COVID-19 pneumonia in patients requiring a CT abdomen study. As proven in the literature, CT findings of COVID-19 pneumonia have a higher sensitivity than the PCR test.

We report here an unusual case of eosinophilic necrotizing inflammation of the lung that mimicked chronic eosinophilic pneumonia. A 71-year-old man who lived in an unsanitary environment and was referred to our hospital with suspected pneumonia. Peripheral blood eosinophilia was observed, and computed tomography indicated extensive consolidation with multiple cystic lesions, mainly in the left lung. A histological analysis using video-assisted thoracic surgery revealed diffuse infiltration of inflammatory cells into the alveolar wall and massive accumulation of macrophages and eosinophils in the airspace. Many tiny eosinophilic abscesses were scattered through the tissue. These findings were more severe than those associated with chronic eosinophilic pneumonia. Immunostaining revealed the deposition of eosinophil granular protein and the presence of extracellular traps and Charcot-Leyden crystals, which suggested excessive eosinophil activation. Interestingly, the patient's symptoms and clinical findings gradually improved without treatment after admission. He was discharged to a clean residence and did not have a recurrence for 19 months. The observations suggest a hypersensitivity reaction to an environmental allergen and consequent multiple cyst formation in association with eosinophilic necrotizing inflammation, although further studies are warranted.
