Objective. Rare case presentation of thyroid cartilage variation causing globus sensation and dysphagia.Method. Case report and review of the literature concerning thyroid cartilage variant of clinical significance.Results. Middle-aged male patient presented with globus sensation and painful swallow without previous injury of the larynx. Clinical examination and diagnostic procedures revealed a rare anatomic aberrance of the thyroid cartilage. Surgical treatment was declined by the patient who accepted a yearly followup.Conclusion. Morphometric studies do not report the dislocation of the superior thyroid cornu, and very few cases have been described either of which were attributed to trauma or to unknown cause. The present case is to be added to the very few cases of superior thyroid cornu dislocation of unknown aetiology. Clinicians should be aware of this rare variation using CT neck as the imaging study of choice. Direct endoscopy rules out any synchronous disease or malignancies.

Sixth Decade

The degree of ossification of the thyroid cartilage in anthropological studies is related to other methods of determining the age of a skeleton. The endochondral ossification process begins at the age of approximately 15–20 years and is generally completed in the fifth or sixth decade of life. In the present case, early and complete mineralization of the thyroid cartilage of a skeleton belonging to a 21-year-old young soldier who died in 1946 was observed. Ossified thyroid cartilage at a very young age is rare and may be associated with specific symptoms, such as compression due to trauma, or may also be related to hormonal dysfunction and various diseases that may cause early mineralization. A macroscopic morphological evaluation and radiographic examination of the thyroid cartilage were performed and a decalcification test was applied to a sample taken from the thyroid cartilage to confirm that the structure was indeed mineralized. There is nothing to exclude that this is simply a physiological anatomical variation. Knowledge of this rare anatomical abnormality at a young age would be useful for the diagnosis of various pathological conditions.

Symptomatic Stenosis

Foetal-type posterior circle of Willis is a common anatomical variation with a variable degree of vessel asymmetry. In patients with this abnormality, carotid endarterectomy (CEA) may create cerebral hypo-perfusion intraoperatively, and this may be underestimated under general anaesthesia. There is currently no evidence that anatomical variations in the circle of Willis represent an independent risk factor for stroke. Moreover, there is a paucity of data on treating patients with such anatomical variations and co-existing ICA stenosis. We present a case of CEA under local anaesthesia (LA) in a 52-year-old female patient with symptomatic stenosis of the right ICA and coexistent foetal-type posterior circle of Willis. There were no post-operative complications and she was discharged free from symptoms. She was seen again 3 months later and was free from complications. This case higlights that LA should be strongly considered to enable better intra-operative neurological monitoring in the event of foetal-type posterior circle of Willis.

Abstract Background The etiology of carpal tunnel syndrome (CTS) is multifactorial. Static mechanical characteristics of CTS have been described, but dynamic (muscular) parameters remain obscure. We believe that musculature overlying the transverse carpal ligament may have an effect on carpal tunnel pressure and may explain the prevalence of CTS in manual workers. Questions/Purposes To utilize magnetic resonance imaging (MRI) imaging to estimate the amount of muscle crossing the area of the carpal tunnel and to compare these MRI measurements in patients with and without documented CTS. Methods A case–control study of wrist MRI scans between January 1, 2018, and December 1, 2019, was performed. Patients with a diagnosis of CTS were matched by age and gender with controls without a diagnosis of CTS. Axial MRI cuts at the level of the hook of the hamate were used to measure the thenar and hypothenar muscle depth overlying the carpal tunnel. Muscle depth was quantified in millimeters at three points: midcapitate, capitate–hamate border, capitate–trapezoid border. Average depth was calculated by dividing the cross-sectional area (CSA) by the transverse carpal ligament width. Statistical analysis included Student's t-test, chi-square test, and Pearson's correlation coefficient calculation. Results A total of 21 cases and 21 controls met the inclusion criteria for the study. There were no significant differences in demographics between case and control groups. The location and depth of the musculature crossing the carpal tunnel were highly variable in all areas evaluated. A significantly positive correlation was found between proximal median nerve CSA and muscle depth in the capitate–hamate area (correlation coefficient = 0.375; p = 0.014). CSA was not significantly associated with chart documented CTS. Conclusions We found large variability in our measurements. This likely reflects true anatomical variation. The significance of our findings depends on the location of the muscles and the line of pull and their effect on the mechanics of the transverse carpal ligament. Future research will focus on refining measurement methodology and understanding the mechanical effect of the muscular structure and insertions on carpal tunnel pressure. Level of Evidence This is a Level 3, case–control study.

Mitral Valve Vegetation

Myocardial infarction is the leading cause of papillary muscle rupture. This complication occurs in up to 5% of cases post MI and although rare, it constitutes a cardiac emergency if left untreated. On this basis, a 59-year-old male presented with low-grade fever and atypical chest pain with raised inflammatory markers and troponin levels. He was treated for infective endocarditis after echocardiography revealed a mass on the mitral valve, which was presumed to be a mitral valve vegetation and so he completed a 6-weeks course of antibiotics followed by elective mitral valve replacement surgery. During surgery, it was discovered that there was no endocarditis. Instead an unusually small muscle head of one of the posteromedial papillary muscle groups had ruptured secondary to an inferior myocardial infarction. This ruptured muscle head was highly mobile and mimicked a mitral valve vegetation. The mitral valve was successfully repaired, and the right coronary artery grafted. He made a full recovery but developed new-onset atrial fibrillation for which he is awaiting elective cardioversion. One should have a high index of suspicion for diagnosing papillary muscle rupture as it may mimic valvular vegetation on echocardiography, especially if the papillary muscle involved is an anatomical variant.

Three cases of prenatal diagnosis of malformations associated with abnormal urorectal septum development were presented at 12, 20 and 31 weeks of gestation. The difficulty to diagnose this group of malformations is reported to depend on the characteristics of the echographic pattern at various stages of pregnancy due to a complex multi-system anatomical variation.

A 57-year-old male chronic smoker with underlying diabetes mellitus presented with dysphonia associated with cough, dysphagia and reduced effort tolerance of 3 months’ duration. Videoendoscope finding revealed bilateral polypoidal and erythematous true and false vocal fold with small glottic airway. The patient was initially treated as having tuberculous laryngitis and started on antituberculous drug. However, no improvement was observed. CT of the neck showed erosion of thyroid cartilage, which points to laryngeal carcinoma as a differential diagnosis. However, the erosion was more diffuse and appeared systemic in origin. The diagnosis of laryngeal perichondritis was made when the histopathological examination revealed features of inflammation, and the tracheal aspirate isolated Pseudomonas aeruginosa. The patient made a good recovery following treatment with oral ciprofloxacin.
