RESUMEN
INTRODUCTION: Pilocytic astrocytoma is a low-grade glioma more frequently seen in patients <20. It is pretty uncommon in the spinal cord. Rarely, astrocytoma may involve the most or total length of the spinal cord; in that case, they are called "holo-cord astrocytoma." In this case report, we are reporting the third holo-cord pilocytic astrocytoma in an adult patient and the first with an extension to the Magendie foramen. CASE PRESENTATION: We presented a 24-year-old woman with complaints of progressively worsening neck and back pain since one year ago. The patient's MRI showed a very large intradural and intramedullary cystic lesion with a solid component within the spinal cord extending from the medulla to the conus medullaris. Partial resection of the solid part of the cervical portion of the tumor was performed. Histopathological evaluation of the resected tumor segments was compatible with grade I pilocytic astrocytoma. After one year of follow-up, neck and back pain has reduced, and neurological functions have improved. CONCLUSION: Spinal cord pilocytic astrocytoma may present as a holo-cord tumor and can rarely extend to the intracranial fossa. Although this tumor does not arise from the central canal, in this case, it was extended through the Magendie foramen. Symptoms could be subtle despite extensive cord involvement. On MRI, this tumor presents as an intramedullary holo-cord cystic lesion intermixed with a solid component with a variable enhancement of the solid component.

In this study, we reported a previously immunocompetent patient who developed cytomegalovirus-induced gastric ulcers after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A 33-year-old man was referred to our center with complaints of persistent dysphagia and odynophagia, and epigastric pain and discomfort after ingesting solids or liquids, a few days after his hospital discharge following admission to treat coronavirus disease 2019 (Covid-19). Endoscopy revealed inflammation and a whitish exudate in the esophagus, and multiple large active ulcers in the stomach. Histopathological and immunohistochemical findings were strongly suggestive of cytomegalovirus infection.
RESUMEN
BACKGROUND: Dysfunction of both the innate and the adaptive immune systems is observed in severe coronavirus disease 2019 which, together with administration of immunosuppressive drugs, could lead to cytomegalovirus coinfection or reactivation associated with a poorer outcome. The current study aimed to systematically review the pattern, presentations, clinical course and outcome of patients with severe acute respiratory syndrome coronavirus 2 and cytomegalovirus coinfection. METHODS: Three online databases, PubMed, Scopus and Web of Science, were searched, and after excluding duplicates and irrelevant reports, eligible articles were identified. Information about patients' age and gender, comorbidities, presentations of coronavirus disease 2019 and cytomegalovirus, treatment courses and outcomes were extracted. RESULTS: A total of 34 reports with 59 patients with coinfection were considered to be eligible for data extraction. A majority of patients were middle-aged or elderly (84.5%). More than three-fourths (79.2%) had at least one comorbidity. Cytomegalovirus viremia was documented in 43 patients. The most common end organ involved was the gastrointestinal tract in 13 patients (48.1% of 27 patients with end organ involvement), mostly as cytomegalovirus colitis, followed by the respiratory tract in 12 patients. There was a significant association between intubation and fatal outcome (p = .011). CONCLUSION: We comprehensively reviewed published cases with coronavirus disease 2019 and cytomegalovirus reactivation. The findings may assist in appraising signs and symptoms for early suspicion, detection and treatment in patients with unusual clinical courses or with severe, prolonged or unexplained deterioration of end organ function.
