Ustazah Cantik Kelompok Siswa Neurologic dysfunction resulting in vocal cord paralysis most common localizes to the recurrent laryngeal nerve, but can also be due to upstream lesions affecting the vagus nerve (from which the recurrent laryngeal nerve branches off) or the brain. Three reliable imaging findings associated with vocal cord paralysis were identified on routine axial ct studies: ipsilateral pyriform sinus dilatation, medial positioning and thickening of the ipsilateral aryepiglottic fold, and ipsilateral laryngeal ventricle dilatation.
Ustazah Cantik Kelompok Siswa Vcp is reliably identified at ct by recognizing key findings at the level of the true vocal cords. the most sensitive signs on ct scans are ipsilateral piriform sinus dilatation, medial rotation and thickening of the aryepiglottic fold and ipsilateral laryngeal ventricle dilatation. Ct for unilateral vocal cord paralysis is discussed in terms of normal neurologic anatomy, ct signs of paralysis, mimics and imaging pitfalls, and various mediastinal causes of paralysis. Background and purpose: several ct findings are thought to be indicative of vocal cord paralysis; however, these signs have never been validated in a blinded fashion. this study attempts to compare and validate these signs and determine their accuracy in predicting vocal cord paralysis. Vocal cord paralysis (vcp) may be caused by a variety of mediastinal disease entities, including various neoplastic, inflammatory, and vascular conditions, and may be the presenting symptom of an otherwise clinically occult disease.

Vocal cord paralysis (vcp) may be caused by a variety of mediastinal disease entities, including various neoplastic, inflammatory, and vascular conditions, and may be the presenting symptom of an otherwise clinically occult disease. The most common tests were rheumatoid factor (38%), lyme titer (36%), erythrocyte sedimentation rate (34%), and antinuclear antibody (33%). Ct of the neck demonstrates typical signs of paralyzed right vocal cord including medial deviation of the posterior part of the right vocal cord, dilatation of the right pyriform sinus compared to the contralateral side and, medial deviation of the aryepiglottic fold. Mri is preferred for evaluating central causes of paralysis. contrast enhanced ct is ideal for assessing the extracranial course of the vagus and recurrent laryngeal nerves from the skull base to the aortopulmonary window.
