Introduction and objective: A cervical rib clinically manifests as a hard supraclavicular lump, which may initially suggest malignancy. The objective of the present work is to illustrate its presentation, to make the suspicion and diagnosis of it easier and thereby offering the patient a benign diagnosis. Method: We present three clinical cases of cervical rib seen in the ENT service of our hospital. Discussion: Information from the clinical interview and physical exam along with a simple thorax radiography should be sufficient to distinguish this entity from a malignant process. Conclusions: In the differential diagnosis of a hard supraclavicular mass, we should consider the possibility of a cervical rib. [ABSTRACT FROM AUTHOR]

Introduction and objective: Discovering a hard supraclavicular mass is a worrisome finding because it usually implies an underlying malignancy. The objective of this work is to illustrate the clinical presentation and characteristics of a cervical rib, because as unusual as this entity may be, suspecting of it offers an immediate diagnosis, avoids unnecessary explorations and presents a benign diagnosis to the patient. Method: A systematic review about the differential diagnosis of hard supraclavicular masses is carried out by two independent revisers using five different academic search engines. Results: From the 96 articles found in the initial search, 14 that matched the inclusion criteria were chosen. The approach of these selected articles was the differential diagnosis of a cervical rib in patients with a hard supraclavicular mass. Discussion: Soliciting complimentary tests delays a diagnosis that can be easily made through a simple thorax radiography, saving the patient from the distress of tortuous pathway. Conclusions: The differential diagnosis of a hard supraclavicular mass should include the possibility of a cervical rib. [ABSTRACT FROM AUTHOR]

Introduction: Thoracic Outlet Syndrome - TOS - is a heterogeneous and potentially dysfunctional group of syndromes related to extrinsic compression of neurovascular structures from the neck to the upper limb for different congenital or acquired anatomical structures, being more frequent the neurological compression, causing a variety of symptoms that vary according to the degree of compression and affected structure that in some cases make it difficult to diagnose. Due to the lack of established diagnostic criteria, the physical exam is the most important element used to formulate a diagnosis. The initial treatment is conservative. The surgical treatment becomes an option with multiple personalized procedures for each type of patient according to the etiology. Objective: The purpose of the article is to discuss the clinical case based on the evidence allowing general knowledge of that pathology, and understanding the causes of pain in the upper limb, to therefore guide medical staff to perform a timely diagnosis and effective treatment that decreases the risk of irreversible complications. Results and conclusions: A study case of a young adult patient presenting neurovascular symptoms due to syncope, left anterior thoracic pain, localized pain in the upper limbs, sensation of lumps in the neck, paresthesia, decrease in muscular strength, edema, pallor and coldness of the limb was presented. A radiological diagnostic test in the accessory cervical rib was performed and later confirmed with a nuclear resonance. Thoracic Outlet Syndrome in the left side was diagnosed resulting in surgery. It was necessary to perform supraclavicular approach, scalenotomy, decompression of brachial plexus and subclavian artery. Later, the patient's health vastly improved. [ABSTRACT FROM AUTHOR]
