Its occurrence in previously healthy young adults is uncommon, often with delayed diagnosis, and may coexist with under-recognized predisposing factors. In this case, family clustering of vague gastrointestinal symptoms and a coexisting parasitic infestation are most likely incidental rather than causative.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>\n                      A previously healthy young Saudi woman presented with 2 weeks of intermittent colicky abdominal pain, low-volume diarrhea, and a final acute episode of severe pain with progressive abdominal distension. Her 15-year-old sister had recently been diagnosed with enterobiasis with a similar symptom pattern. Vital signs were stable; abdominal examination showed mild distension without peritonism. Plain radiography demonstrated dilated colonic loops, and contrast-enhanced computed tomography revealed a markedly dilated sigmoid colon (up to 85\u2005mm), an abrupt collapse point, and the whirl sign, consistent with sigmoid volvulus. Endoscopic detorsion was achieved successfully with placement of a rectal decompression tube; during colonoscopy, a single adult gravid\n                      <jats:italic>Enterobius vermicularis<\/jats:italic>\n                      was retrieved and confirmed parasitologically (characteristic ova demonstrated within the gravid female), prompting consultation with an infectious diseases team and a course of mebendazole. Following clinical stabilization, the patient underwent laparoscopic sigmoidectomy with extracorporeal stapled colorectal anastomosis. Operative findings confirmed a redundant sigmoid colon without ischemia, perforation, or contamination. Histopathology revealed ischemic-type changes (mucosal atrophy, submucosal edema, congested vessels, and hypertrophied muscularis propria) with viable resection margins. At the 4-week follow-up, she was asymptomatic and repeat parasitological testing (stool microscopy and adhesive tape examination) showed no\n                      <jats:italic>E. vermicularis<\/jats:italic>\n                      ova.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Sigmoid volvulus should be considered in young adults presenting with acute colonic obstruction, particularly when imaging features are characteristic. A two-stage strategy of colonoscopic detorsion followed by definitive laparoscopic sigmoidectomy is feasible and effective in hemodynamically stable patients without ischemia. The clinical relevance of the coexisting enterobiasis remains hypothesis-generating and should not be overstated.<\/jats:p>\n
