Case Report: Severe back pain, epigastric distress and refractory nausea; an unusual presentation of mediastinal bronchogenic cyst

Background: Bronchogenic cysts are congenital malformations from abnormal budding of embryonic foregut and tracheobronchial tree. We present a case of bronchogenic cyst with severe back pain, epigastric distress and refractory nausea and vomiting. Case Presentation: A 44-year-old Hispanic female presented with a 3-week history of recurrent sharp interscapular pain radiating to epigastrium with refractory nausea and vomiting. She underwent cholecystectomy 2-years ago. Computed tomography (CT) abdomen at that time showed a subcarinal mass measuring 5.4 X 5.0 cm. Subsequent endoscopic ultrasound diagnosed it as a bronchogenic cyst. Endobronchial ultrasound (EBUS) guided aspiration resulted in incomplete drainage and she was discharged after partial improvement. Current physical examination showed tachycardia and tachypnea with labs showing leukocytosis, elevated inflammatory markers, and hypokalemic metabolic alkalosis. CT chest showed an increased size of the bronchogenic cyst (9.64 X 7.7 cm) suggestive of possible partial cyst rupture or infected cyst. X-ray esophagram ruled out esophageal compression or contrast extravasation. Patient’s symptoms were refractory to conservative management. The patient ultimately underwent right thoracotomy with cyst excision that resulted in complete resolution of symptoms. Conclusion: Bronchogenic cysts are the most common primary cysts of mediastinum with the prevalence of 6%. The most common symptoms are chest pain, dyspnea, cough, and stridor. Diagnosis is made by chest X-Ray and CT chest. Magnetic resonance imaging chest and EBUS are more sensitive and specific. Symptomatic cysts should be resected unless surgical risks are high. Asymptomatic cysts in younger patients should be removed due to low surgical risk and potential late complications. Watchful waiting has been recommended for asymptomatic adults or high-risk patients. This case presents mediastinal bronchogenic cyst as a cause of back, nausea and refractory vomiting. Immediate surgical excision in such cases should be attempted, which will lead to resolution of symptoms and avoidance of complications.

A Long-Term Follow-Up Result of Pouch Plasty for Severe Dysfunction of Jejunal Pouch Reconstruction After Total Gastrectomy: A Case Report

A 78-year-old woman with malignant lymphoma of the stomach underwent total gastrectomy with a jejunal-pouch (J-pouch) reconstruction in 1994. Twelve years after surgery the patient began to suffer epigastric distress and reflux symptoms. Eventually, she was unable to take anything by mouth. A series of diagnostic images seemed to indicate that the main cause of the dysfunction was flaccidity of the J-pouch and deformity of the outflow route induced by chronic excessive dilatation of the pouch wall. Because all conservative managements only led to temporary improvement and ended in failure, she hoped to receive the operation. We designed “pouch plasty” capable of ameliorating the pouch dysfunction. The aim of pouch plasty was to improve uneven tension of the pouch wall and repair deformity of the outflow route of the food. After the operation, the J-pouch resumed adequate drainage and had good reservoir function. More than 7 years later, the patient had no further complications.

Poisoning due to raw Gyromitra esculenta (false morels) west of the Rockies

ABSTRACT Vomiting with abdominal pain is a common presentation in the emergency department (ED). Without a careful history, unusual causes, such as toxic ingestion, may evade diagnosis. We report a case of an Asian couple who presented to the ED with vomiting and epigastric distress. They were discharged with no definite diagnosis, but on a return ED visit the following day were diagnosed with toxic ingestion of Gyromitra esculenta, commonly known as the western false morel. The patients were admitted and treated with intravenous hydration and pyridoxine. Both patients developed mild hepatotoxicity but went on to fully recover. This case demonstrates that the western false morel may cause significant toxicity and it highlights the importance of obtaining a complete history in patients who present with non-specific gastrointestinal symptoms.
