Supernumerary intrathoracic rib, a rare congenital anomaly: Case report and review of the literature

Surgical resolution of chronic thoracic pain stemming from a rare osteo-muscular conflict: A case report

INTRODUCTION

Chronic thoracic pain presents significant diagnostic and therapeutic challenges, particularly when arising from rare osteo-muscular conflicts. This report details a unique case of chronic pain due to an osteo-muscular conflict between the right tenth rib and the internal oblique muscle, highlighting the complexities involved in diagnosis and the potential for surgical resolution.

CASE PRESENTATION

A 33-year-old male with a decade-long history of chronic right hemithorax pain, unresponsive to conservative treatments, underwent diagnostic evaluation. Advanced imaging techniques, including a thoracic CT scan, revealed an ipodense area between the ninth and tenth ribs, suggesting an osteo-muscular conflict. Surgical intervention, specifically a partial costectomy of the right tenth rib, was pursued, resulting in significant symptom relief and improved quality of life.

CLINICAL DISCUSSION

This case underscores the importance of considering advanced diagnostic evaluations in persistent chronic pain cases and the effectiveness of targeted surgical interventions in resolving anatomical conflicts. It contributes to the body of knowledge on managing complex musculoskeletal conditions and underscores the need for personalized treatment approaches.

CONCLUSION

Surgical intervention in selected cases of chronic pain due to rare anatomical conflicts can offer significant relief and enhance patient outcomes. This case advocates for a nuanced approach to the diagnosis and treatment of chronic thoracic pain, emphasizing the role of advanced imaging and the potential benefits of surgical resolution.

Contrast-Enhanced Ultrasound of the Chest in Children and Adolescents: A Pilot Study for Assessment of Added Diagnostic Value

OBJECTIVES

To determine the added diagnostic value of contrast-enhanced ultrasound (CEUS) in pediatric chest abnormalities by comparing interpretation of CEUS studies and confidence level to conventional US studies.

METHODS

CEUS studies in patients with a variety of clinically suspected chest abnormalities performed between 2016 and 2020 were reviewed and compared to same-day conventional US studies. Examinations were independently interpreted by 4 radiologists blinded to clinical and other imaging data. Rater confidence was classified as low, moderate, or high. Diagnostic accuracy was determined by comparing image interpretation to patient outcome as the ground truth. Interobserver agreement was also assessed.

RESULTS

Sixteen patients (10 male) with 18 CEUS studies were included. Median rater agreement with ground truth was significantly higher for CEUS (100%) than conventional US (50%; P = .004). Median rater confidence was high (3.0) for CEUS, and low-moderate (1.5) for conventional US (P < .001). CEUS sensitivity (54.6-81.8%) and specificity (63.4-100.0%) were greater than conventional US (45.5-72.7% and 12.5-63.5%, respectively). CEUS false positives (0-4) and false negatives (2-5) were fewer than conventional US (4-7 and 3-6, respectively). Except for one rater pair where agreement was substantial (κ = .78, P < .01), inter-rater agreement for CEUS for all other rater pairs was nonsignificant (κ = .25-0.51, P ≥ .07). Agreement for conventional US was moderate and statistically significant for 3 rater pairs (κ = .55-0.78) and nonsignificant for the remaining 3 rater pairs (P ≥ .06).

CONCLUSIONS

CEUS adds diagnostic value to the assessment of a variety of chest abnormalities. The data support further evaluation of the role of CEUS as a non-invasive, problem-solving technique in children.

Intrathoracic rib: rare rib anomaly, review of the literature and proposal for classification

Background: Intrathoracic ribs are very rare congenital anomalies, and often discovered incidentally on chest X-ray. Since its first description by Lutz in 1947, approximately 50 cases have been reported in the literature till date. The aim is to review the all reported intrathoracic ribs, summarize their clinical features, and propose a potential classification. Methods: All relevant literatures were searched and reviewed. The terms include intrathoracic rib, intrathoracic bifid rib, trans-thoracic rib and intrathoracic rib anomaly. We have summarized the first finding events, origination, distribution, related anomalies and imaging features of intrathoracic rib, and propose an updated classification. Results: The patients' age at initial finding was from six weeks to 79 years old. Of all, sixty percent was less than 30 years old. There was no difference in gender. Most of them were reported by authors in western countries (85.3%, 58/68), and incidental findings by radiologist and respiratory physician. The intrathoracic rib occurs more frequently on the right side, and is usually single and unilateral. According to the new classification, type I and II was account for 45.6% and 35.3%, respectively. Conclusion: Intrathoracic rib is rare findings in clinical practice. It is useful that radiologists or clinician are familiarized with the imaging appearances of these malformations. These anomalies reflect some disturbances during the embryo development, leading us to propose a potential classification that could contribute to a better understanding of this rib anomaly.
