RESUMEN
Diverticulitis in a solitary transverse colon diverticulum is uncommon, with only a handful of cases documented in the literature. There are various clinical manifestations of the disease, which make clinical and radiological diagnosis rather challenging. Herein, we present a case of a premenopausal female patient in her late 40s who presented to the emergency department, complaining of right lower quadrant abdominal pain, nausea, anorexia and fever. Following clinical, biochemical and radiological tests, the patient was prepared for surgical operation, with the presumed diagnosis of acute appendicitis. An appendicectomy was planned via a McBurney incision. Notably, no inflammation of the appendix was discovered. However, on further exploration, an inflammatory mass was identified in the transverse colon, which was subsequently excised and sent for histological examination. The histology results confirmed the presence of a ruptured solitary transverse colon diverticulum, accompanied by an adjacent mesenteric abscess. The patient's postoperative recovery was uneventful.

A 61-year-old man present to us with continued abdominal pain without abdominal tenderness for 1 month. Blood testing showed elevated biliary enzymes and inflammation. Contrast-enhanced computed tomography (CT) revealed thickening of the transverse colon with relatively strong enhancement but no bile duct dilatation. Colonoscopy revealed localized edema and granular mucosa in the transverse colon. Fluoroscopic endoscopy exhibited the absence of haustra. Multiple biopsies were performed, but differentiation between mild inflammation and mucosa-associated lymphoid tissue (MALT) lymphoma was inconclusive. To establish a definitive diagnosis, transgastric endoscopic ultrasound-guided fine needle biopsy of the hypoechoic mass was performed. Histopathological analysis exhibited the proliferation of small-sized lymphocytes. Fluorescence in situ hybridization revealed the characteristic API2-MALT1 translocation of MALT lymphoma. We performed liver biopsy to investigate biliary enzyme elevation. Histopathology confirmed lymphocytic infiltration within Glisson's capsule. Immunohistochemistry showed positive for CD20 and negative for CD3 and CD5, signifying the infiltration of MALT lymphoma in the liver. Based on these findings, we diagnosed MALT lymphoma, Lugano classification Stage IV. We performed bendamustine-rituximab (BR)-combined therapy. After six courses of BR-combined therapy, colonoscopy revealed improvement in the lead pipe sign and CT revealed disappearance of the mass.

INTRODUCTION: Splenic artery aneurysm (SAA) is a focal dilation of the splenic artery with varying etiologies including atherosclerosis, arteritis, or trauma. Giant SAAs with a diameter of 10 cm is rare and can lead to severe complications like rupture and fistulas. Therefore, an accurate and timely diagnosis and treatment are important. PATIENT CONCERNS: A 50-year-old male presented with acute epigastric pain and hemorrhagic shock. Considering his symptoms and examination, ultrasound, multi-slice computed tomography and digital subtraction angiography results, a ruptured giant splenic artery aneurysm complicated with an exceptional gastric and transverse colonic fistula was suspected. DIAGNOSIS: Ruptured giant splenic artery aneurysm. INTERVENTIONS: Left anterolateral thoracotomy to control the severe aortic bleeding just above the diaphragm, aneurysmectomy, splenectomy, and closing the gastric and transverse colon perforations. OUTCOMES: Multi-slice computed tomography demonstrated the presence of splenic artery aneurysm in the distal third measuring (10â ×â 12 cm) in diameter with a true lumen measuring (7â ×â 3.5 cm) and a large hematoma extending to the greater and lesser gastric curvature. Intraoperatively, a large pulsating mass was detected occupying the epigastrium and the left hypochondrium with severe adhesions with the stomach and transverse colon. CONCLUSION: Giant SAA with a diameter of 10 cm is rare and is associated with severe complications. Therefore, successful treatment of splenic artery aneurysms involves prompt diagnosis, immediate surgical intervention to control bleeding, and tailored approaches like thoracotomy to control the thoracic aorta for better hemodynamic stabilization, aiming to eliminate the aneurysm and reduce complications effectively.

SUMMARY: Transverse colon volvulus is a rare diagnosis, with less than 100 cases reported up to 2019. The condition is complicated by the absence of characteristic radiological findings and is typically diagnosed intraoperatively. It is a surgical emergency as the condition can lead to bowel necrosis and is associated with a mortality rate of up to 33%. Bowel resection is the treatment of choice, and if a megacolon is present a subtotal colectomy is recommended. Due to the rarity of transverse colon volvulus, limited data is available on the long-term outcome of patients.

The volvulus of the colon is a relatively common cause of colonic obstruction, mainly in the sigmoid colon, less frequent in the caecum, and rarely in the transverse colon. Multidetector tomography (MDCT) is able to establish the diagnosis showing dilated loops of proximal right and transverse colon, which depend on the time scale of evolution, with an abrupt transition site at the splenic flexure and a secondary torsion of the transverse colon mesentery. Volvulus of the transverse requires surgical detorsion in adults. Among the therapeutic options, simple detorsion or detorsion associated with a colopexy are included, but both have high rates of recurrence compared to resection techniques. Surgical resection of the involved segment is required prior to gangrene and perforation. Resection with or without primary anastomosis is the treatment of choice and prevents recurrence. The transverse colon volvulus is a disease of very low frequency and clinical diagnosis may be difficult. The management remains controversial. We stress that although many surgeons will never see a case of transverse colon volvulus, it should be considered as a differential diagnosis of intermittent abdominal pain or acute intestinal obstruction.
