Congenital cysts of the mediastinum are infrequent; their prevalence in the adult population is higher than in children. An esophageal duplication cyst is the second more frequent duplication of the gastrointestinal tract after ileal duplications. Cysts of the foregut result from an abnormal division of the primitive intestine. Histologycally, a cyst is a muscular sac lined with stratified epithelium. It is usually asymptomatic and in half of the patients it is an incidental finding. In the aetiology chest pain, a cyst of the digestive tract is a rare occurrence. On the other hand fever and acute pain can be caused by maceration or rupture of the cyst. Cysts have been associated with spinal abnormalities such as spina bifida, hemivertebrae and vertebral fusion defects. [ABSTRACT FROM AUTHOR]

Intestinal obstruction is very common in cancer patients and occurs in 80% of cases with malignant aetiology. Hence, aggressive treatment is needed in most cases. The occlusion can be caused by luminal obstruction, paralysis of the intestinal muscle or carcinomatosis with mesentery involvement. The clinical case we present is that of a patient diagnosed as having lung cancer and who was admitted with paralytic ileus following treatment with vinorelbine; a vinca alkaloid whose main characteristic toxicities include neutropenia and peripheral neuropathy. Also, on rare occasions, the drug can cause paralysis of the ileum due to autonomic neuropathy. Hence, before administering aggressive treatment to an occlusive syndrome, cases that could benefit from conservative treatment should be ruled out. [ABSTRACT FROM AUTHOR]
