Background: The Coronavirus was first discovered in December 2019 and quickly it turned into a pandemic called coronavirus disease 2019 (COVID-19). The main symptoms of infection with this virus were constitutional and respiratory symptoms. However, one-third of COVID-19 patients also developed neurologic manifestations, including Guillan-Barre syndrome (GBS), which was one of the most critical complications. Case presentation: In this paper, the authors present seven patients who suffered from GBS after being infected with the Coronavirus or in conjunction with the infection. Nerve conduction studies showed axonal type in four patients, and demyelinating type in three patients. Neurological symptoms were the initial symptoms in two patients and the presence of COVID-19 was later discovered. Most of the patients had an excellent recovery. Conclusion: In the medical literature, many articles have mentioned the association of GBS with the Coronavirus, and it is considered the most common peripheral neurologic complication for the virus, but this article is considered one of the very few articles that were published from the Middle East, especially from Syria. Guillain-Barre’s occurrence after infections is known, and the Coronavirus is one of the most important viruses of the era, which incited an increase in the number of Guillain-Barre patients.

Introduction and importance: Peritoneal hydatid cyst is a rare disease which transplants by eggs of Echinococcus. Peritoneal cysts are divided into primary and secondary. This case shows an unusual manifestation of peritoneal hydatid cysts, adding to the already known manifestations of this disease in medical literature. It is important because peritoneal hydatid cysts maybe life-threatening if it is not managed carefully. Case presentation: In this case, we present a patient with history of recurrent hepatic hydatid cysts who presented with symptoms of gastric outlet obstruction. CT showed multiple peritoneal cysts consisting with peritoneal hydatid cysts located at the level of stomach pylorus. Although the patient suffered from multiple surgeries for recurrent hydatid cysts, she accepted the surgical option. The patient was discharged 10 days later after a non-complicated surgery. Albendazole was recommended after surgery. Clinical discussion: The mechanism of peritoneal hydatid cysts is still unknown, but one of theories declares that microrupture can explain the disease. Conclusion: This case emphasizes the idea that peritoneal hydatid cysts should be considered even in patients presenting with atypical symptom (eg, Gastric outlet obstruction). Highlights
