Background: Gallstone ileus is a rare cause of bowel obstruction, often presenting with nonspecific symptoms that delay diagnosis. This study assessed the diagnostic value of CT imaging and its correlation with histopathological findings in confirmed cases. Methods: A retrospective analysis of 14 patients with surgically confirmed gallstone ileus was performed. All underwent abdominal radiography, ultrasound, and CT. Imaging findings were evaluated for calcification type, impaction site, and fistula presence. Histopathology from surgical specimens was used for correlation. Relative risk (RR) and 95% confidence intervals (CIs) were calculated, with adjustments for small sample size. Results: Rim-calcified gallstones were the most common (50%) and significantly associated with chronic inflammation (RR 1.42, 95% CI: 1.05–1.93). Cholecystoduodenal fistulas were most frequent (57.1%), with a 92.8% imaging-pathology concordance. Ileal impaction (35.7%) was linked to increased risk of bowel necrosis (RR 2.0, 95% CI: 1.1–3.6). All stones were >3 cm; two patients had recurrence. No perioperative mortality occurred. Conclusions: CT imaging demonstrates high diagnostic accuracy and strong correlation with histopathological findings in gallstone ileus. Identifying calcification patterns and impaction sites aids early diagnosis and surgical planning.

Background and Objectives: Superior mesenteric artery syndrome (SMAS) is an uncommon cause of proximal duodenal obstruction that requires clinicoradiological correlation. Materials and Methods: We retrospectively reviewed 13 patients with SMAS identified at the Clinical County Emergency Hospital Bihor, Romania, during 2019–2024. Clinical records and contrast-enhanced computer tomography (CT) examinations were reviewed descriptively. Results: The cohort included 13 adults aged 19–85 years (mean 45.5 ± 17.8; median 43 years). Abdominal pain was reported in 12/13 patients (92.3%), vomiting or emetic symptoms in 6/13 (46.2%), feeding difficulty or appetite disturbance in 5/13 (38.5%), and documented weight loss in 3/13 (23.1%). CT measurements were available for the aortomesenteric angle in 7/13 patients (range, 10–25°) and for the aortomesenteric distance in 8/13 (range, 3–8 mm); direct third-part duodenal compression and proximal dilatation were interpreted together with compatible symptoms. Imaging showed Nutcracker-type left renal vein compression in 3/13 patients (23.1%) and possible May–Thurner anatomy in 1/13 (7.7%); these findings were not adjudicated as clinical syndromes without corresponding manifestations. Based on the management labels, 9/13 patients (69.2%) underwent surgery at some point and 4/13 (30.8%) received medical therapy only. Standardized follow-up and procedure-level outcome data were not available for all patients. Conclusions: This small, retrospective series is descriptive and cannot estimate prevalence, diagnostic delay, or comparative treatment effectiveness. It illustrates heterogeneous adult presentations and supports interpreting aortomesenteric measurements together with compatible symptoms and evidence of duodenal obstruction.
