Mucinous cystic neoplasms (MCN) are an uncommon form of exocrine neoplasms of the pancreas. Symptoms are most often vague and this makes the diagnosis more difficult. The current case is one of three cases yet reported where the MCN caused left-sided portal hypertension leading to the formation of isolated gastric varices and subsequent bleeding from the varices. In the previously reported cases the main symptom was hematemesis. However in the current case the patient experienced no hematemesis, only isolated incidents of dark coloured diarrhea, but the main symptoms were those of iron-deficiency anemia. We present the case report of a 34-year-old woman who presented with dizziness and lethargy and was found to have 12 cm MCN in the pancreas.
黏液性囊性肿瘤（MCN）是胰腺外分泌肿瘤的一种罕见形式。症状通常很模糊，这使得诊断更加困难。本病例是迄今报道的三例MCN导致左侧门静脉高压，进而形成孤立性胃静脉曲张并随后发生静脉曲张出血的病例之一。在先前报道的病例中，主要症状是呕血。然而，在本病例中，患者没有呕血，仅有孤立的深色腹泻事件，但主要症状是缺铁性贫血。我们报告一例34岁女性病例，该患者因头晕和嗜睡就诊，发现胰腺有一个12厘米的MCN。
