Liver cysts are formations of serous content surrounded by normal liver parenchyma, without communication with the bile duct. The cyst wall is generally lined with cuboidal epithelium surrounded by layers of connective tissue. They are rare entities in adult patients, generally, they are asymptomatic in 3%, and between 10-15% of all patients will generate symptoms that lead them to consult. A 38-year-old man with an external abdominal tomography study that reported a giant hepatic cyst. Laboratory blood tests: hemoglobin 7.9 g/dl; leukocytosis 11,000/ul; serum electrolytes, liver transaminases, and bilirubin were normal, alkaline phosphatase, and gamma glutamyl-transpeptidase 94 U/l and 241 U/l, respectively. Non-reactive anti-human immuno-deficiency virus (HIV 1) and two antibodies, venereal disease research laboratory (VDRL), cancer antigen (CA) 19-9 antigen, hepatitis B-C surface antigen, and carcinoembryonic antigen were negative. He underwent surgery by laparoscopic drainage of the liver cyst, through a median infraumbilical incision with the Hasson technique and placement of three 12 mm trocars, hepatomegaly was observed without finding an exit site for purulent material, it was punctured through liver segment V, and 2000 ml of citrine fluid was extracted. The hepatic wound is addressed with a 1-0 caliber chromic catgut thread, placing a Penrose-type drain. At 48 hours postoperatively, it evolves favorably, so it is decided to discharge. Hepatic cysts are fluid-filled cavities lined by a single-layered cuboidal or columnar biliary epithelium in the liver. A majority of hepatic cysts are found incidentally on liver imaging, such as abdominal ultrasonography, computed tomography, or magnetic resonance imaging.

There are multiple causes of colocolonic intussusception in adults, such as tumors, autoimmune pathologies, previous abdominal surgeries, and gynecological conditions. Associated complications are small bowel obstruction, ischemia, necrosis, perforation with peritonitis, and sepsis that require urgent attention. A 78-year-old woman who started with colic in the mesogastrium of 5 months of evolution and changes in bowel habits. She went to the emergency room due to intense pain in the mesogastrium. On physical examination, she presented dehydration of the mucous membranes and pale integuments, pain on superficial and deep palpation in the mesogastrium. Admission laboratories: leukocytosis 17,110/ul, neutrophilia 67.9%, hydroelectrolyte imbalance: mild hyponatremia, mild hypochloremia, slightly prolonged coagulation times, normal blood chemistry. Abdominal ultrasound with "pseudokidney" image. Computed tomography reports an image of the introduction of a segment of the transverse colon into a contiguous segment of the same, with data of associated intestinal pneumatosis. Due to the previous findings, an emergency exploratory laparotomy was performed. Invagination of the transverse colon is located, accompanied by dilation of the vessels of the greater omentum; it is reduced manually, an enterotomy is performed and a tumor dependent on the wall is located, for which a 25 cm transverse colon resection, end colostomy and mucous fistula are decided. Pathology report reports inflammatory polyp. In the postoperative period, the patient improved and was discharged. Abdominal pain is the common presentation of intussusception; however, given its rarity in adults, the possibility of missing the finding on abdominal imaging leads to misdiagnosis.
