RESUMEN
Non-iatrogenic trauma of the iliac artery is rarely reported but is always life-threatening. In this report, we describe the case of a child with complete transection and partial disappearance of the iliac artery caused by bicycle handlebar impalement. He experienced catastrophic hemorrhage, malignant arrhythmia, and difficulty in exploring transected vessel stumps. Aggressive infusion, blood transfusion in time, and pediatric vascular characteristics help delay the deterioration during anesthesia induction. Eventually he was successfully rescued by performing interventional balloon occlusion and open revascularization after more than 7 h post-trauma. A series of interventions and precautionary methods may benefit such severely injured patients; thus, these methods should be highlighted.

Introduction: Lymphatic malformations (LMs) are rare vascular anomalies predominantly affecting infants, which can be debilitating or life-threatening when complicated with intralesional bleeding or infection. Effective and safe management strategies are essential in such cases. Case presentation: We report a case series involving four Chinese neonates with life-threatening LMs, initially treated with oral sirolimus. All patients achieved rapid relief and sustained remission, using a lower sirolimus dosage than previously recommended. Furthermore, adverse events were rarely recorded during follow-up. Conclusion: Sirolimus can be considered a promising choice for neonates with intricate and life-threatening LMs. Initiation with a reduced sirolimus dose is advisable.
RESUMEN
BACKGROUND: The typical imaging findings of hairy polyps have been described mostly in case reports. This study was conducted to describe the CT and MRI features of hairy polyps and their common associated abnormalities. METHODS: Medical records of 14 patients with pathological diagnosis of hairy polyps were collected for this study. For each patient, the medical records, including demographics, clinical manifestations, and imaging findings were reviewed. RESULTS: The female-to-male ratio was 3.7:1. The age at first episode varied from birth to 2.7 years. The masses were derived from the back side of the soft palate in seven (50.0%) cases, from the lateral pharyngeal wall in four (28.6%) cases, from the soft palate in one (7.1%) case, from the nasal vestibule in one (7.1%) case, and from the parapharyngeal space in one (7.1%) case. A total of 11 (78.6%) cases presented with pedicled masses containing fat and a central core of soft tissue, there were 3 (21.4%) cases whose imaging findings were atypical, and there were 6 (42.9%) patients who had other pathologies. CONCLUSIONS: Hairy polyps typically presented as pedicled masses containing fat and a central core of soft tissue, but sometimes their imaging findings can be atypical and they can be associated with other congenital abnormalities. CT and MRI are reliable methods for the diagnosis of hairy polyps and their associated abnormalities.
RESUMEN
BACKGROUND: Communicating bronchopulmonary foregut malformation is a rare anomaly characterized by a patent congenital communication between the esophagus or stomach and an isolated portion of the respiratory system. An esophagogram is taken as the gold standard for diagnosis. Compared with esophagography, computed tomography (CT) is more widely used and easily obtained, but CT findings have been described as nonspecific. PURPOSE: To describe CT findings in 18 patients with communicating bronchopulmonary foregut malformation to assist with early diagnosis. MATERIAL AND METHODS: A retrospective review of 18 patients who had proven communicating bronchopulmonary foregut malformation between January 2006 and December 2021 was conducted. For each patient, the medical records, including demographics, clinical manifestations, upper gastrointestinal radiography, magnetic resonance imaging and CT findings, were reviewed. RESULTS: Among the 18 patients, there were 8 males. The right to left ratio was 3.5:1. An entire lung was involved in 10 patients, a lobe or a segment was involved in 7 patients and an ectopic lesion was located in the right neck in 1 patient. The isolated lung may arise from the upper esophagus, mid-esophagus, lower esophagus or stomach, which were detected in 1, 3, 13, and 1 patient, respectively. On chest CT, an extra bronchus which did not arise from the trachea was detected in 14 patients. Contrast-enhanced chest CT was performed in 17 patients, the isolated lung receiving its blood supply from the pulmonary artery in 13 patients, the systemic artery in 11 patients and both pulmonary and systemic arteries in 7 patients. CONCLUSIONS: The presence of an extra bronchus, which does not arise from the trachea, highly suggests the diagnosis of communicating bronchopulmonary foregut malformation. Contrast-enhanced chest CT can provide accurate information regarding the airways, lung parenchyma and vascular structures that is useful to plan surgery.

BACKGROUND: A variety of imaging modalities have been described for the diagnosis of congenital pyriform sinus fistula (CPSF). To date, there have been few MRI reports. PURPOSE: To evaluate MRI findings of CPSF and interobserver reliability. STUDY TYPE: Retrospective. POPULATION: In all, 115 patients aged 23 days to 15.4 years at operation. FIELD STRENGTH/SEQUENCE: 3.0T/axial T1 -weighted image (T1 WI)-SPIR, axial T2 WI, axial T2 WI-STIR, coronal T2 WI-SPIR, diffusion-weighted imaging (DWI), axial and coronal gadolinium-enhanced T1 WI-SPIR. ASSESSMENT: For each patient, the medical records, including demographics, clinical manifestations, and MRI findings were reviewed. All the MRI studies were interpreted by three radiologists independently. STATISTICAL TEST: Kendall's W test was made to determine the interobserver reliability of three reviewers for MRI findings. RESULTS: CPSF occurred on the left side in 104 (90.4%) patients and on the right side in 11 (9.6%) patients. The male-to-female ratio was 59:56. The age at first episode varied from birth to 12.3 years. There was one neonate patient, who presented with a unilocular cystic mass in the left neck. A tunnel-like lesion between the pyriform fossa and the upper pole of the thyroid gland, T2 high signal behind the cricothyroid joint, thyroid gland involvement, deep neck abscesses or masses were noted in 46 (40%), 93 (80.9%), 96 (83.5%), and 36 (31.3%) patients, respectively. There was excellent interobserver reliability for all the MRI findings, ranging from 0.84 to 1.00. DATA CONCLUSION: The sinus tract presenting with a tunnel-like lesion goes behind the cricothyroid joint in most cases. For patients presenting with acute suppurative thyroiditis (AST) or neck infection with thyroid gland involvement, the presence of T2 high signal behind the cricothyroid joint highly suggests the diagnosis of CPSF. MRI is a reliable method for the diagnosis of CPSF. LEVEL OF EVIDENCE: 4 TECHNICAL EFFICACY STAGE: 2.
