We report a case of a morbidly obese young woman in her third trimester of pregnancy presenting with a history of goiter and respiratory disease. The recent history of this patient was significant for worsening respiratory symptoms over a period of 2 weeks, and, on presentation at 36 weeks gestation, she was stridorous, dyspneic at rest, and had a hoarse voice. Evaluation revealed a morbidly obese individual with a large goiter. ⋯ Fiberoptic laryngoscopy revealed a left true vocal cord paresis, and ultrasound evaluation was significant for diffuse multinodular enlargement, with each lobe measuring greater than 10 cm and the isthmus measuring 5. Pulmonary function testing revealed a significant degree of upper airway obstruction without significant lower airway disease. Given the patient's clinical signs and symptoms, her tenuous airway, poor candidacy for urgent tracheotomy, and her proximity to delivery, it was agreed that the patient should undergo elective cesarean section and at its completion undergo subtotal thyroidectomy for the obstructive goiter.

Lateral sinus thrombosis (LST) is a rare but potentially devastating complication of otitis media. We review the clinical presentation, evaluation, management, operative findings, and outcomes of this serious complication. ⋯ LST as a complication of otogenic infections may still pose a serious threat that warrants immediate attention and care. It is frequently associated with other intracranial complications. Contrast-enhanced computed tomography scan and magnetic resonance imaging plays a major role in determining diagnosis and treatment plans. The availability of broad-spectrum antibiotics has improved our management significantly. Conservative surgical intervention including eradication of all perisinus infection and needle aspiration of the sinus seems to be effective.

Congenital anomaly of the carotid artery is a rare abnormality. It is usually discovered incidentally by color Doppler carotid sonography, angiography, computed tomography (CT), or magnetic resonance imaging (MRI) of the head and neck taken for some other reason. Most patients are not symptomatic because of sufficient cerebral circulation supplied to the defective area by the communicating arteries of the circle of Willis, intercavernous anastomosis, communicating arteries from external carotid artery, and by persistent embryologic arteries to the carotid artery territory. However, sometimes, this anatomic variation may eventually lead to some clinical signs and symptoms in particular circumstances in the head and neck of which surgeons are unaware. A retrospective study was designed to emphasize the characteristic radiologic and clinical picture in patients with the congenital absence (agenesis and aplasia) or hypoplasia of the carotid artery, to delineate the associated abnormalities and existing collateral vessels, and to find out its incidence. ⋯ It has been concluded that the combined use of magnetic resonance angiography and CT scanning of the skull base may disclose small but patent ICA. Collateral vessels seem to be usual in such cases, but they may be prominent in cases of acquired vascular occlusion, or increased hemodynamic pressure in dysplastic changes in collateral arteries are known causes of aneurysms. The main vascular supply for the brain in patients with congenitally small (hypoplasia) or absent (agenesis or aplasia) ICA is the vertebrobasilar system in bilateral cases. However, contralateral carotid vessel is the dominant arterial supply for unilateral cases, which has to be borne in mind in surgical interventions to the involved side.
