Spherical Mass

A 2.5-kg, eight-year-old, neutered male Yorkshire Terrier was presented for evaluation of a cervical mass that had first been noticed a year earlier. A firm spherical mass located caudal to the left mandible was found on physical examination. Ultrasonography revealed a well-defined, round-shaped mass located medial to the left mandibular salivary gland that was approximately 2.6 cm in height, 2.3 cm in width and 3 cm in length. Volume-rendered images obtained by computed tomography (CT) showed that the left external and internal carotid arteries and internal jugular vein were encased in the mass. A definitive diagnosis of carotid body tumour was made based on histopathology. The tumour and the carotid arteries and internal jugular vein encased in the tumour were resected using CT-based surgical planning. The regional neural structures were preserved by careful blunt dissection. The dog had a mild hacking cough after swallowing and hoarseness that disappeared spontaneously five days and two months, respectively, after surgery. There was no evidence of recurrence or distant metastasis at 18 months postoperatively. This case report describes successful surgical management of a carotid body tumour with ligation and transection of the carotid arteries in a dog. To the authors’ knowledge, this is the first report of successful surgical treatment of an advanced carotid body tumour based on CT findings.

Objective The purpose of this study is to describe anatomic variations of the internal jugular vein (IJV), inferior petrosal sinus (IPS) and their confluence pattern and implications in IPS catheterization. The anatomic route of IPS after going out of the cranium and its confluence patterns with IJV and will supply knowledge about typing of IPS-IJV junction. Method A review of the literature was performed. Results There might be different routes for entering the intracranial segment of the IPS and multislice spiral computed tomography (MSCT) is effective in identifying the confluences of the IPS with the IJV and their courses. It is important to find the confluence of IPS with IJV for diagnosis and treatment of intracranial lesions via venous route. Meanwhile, IPS diameter at the confluence can significantly affect success of catheterization. Conclusion The classification and the theory of the development of the caudal end of the IPS may be useful in establishing treatment strategies that involve endovascular manipulation via the IPS.

Doppler Waveform

Purpose To evaluate the presence and causes of left brachiocephalic vein (LBCV) steno-occlusive lesions in patients with loss of normal waveform in Doppler ultrasound of the left internal jugular vein (LIJV). Materials and Methods We performed Doppler ultrasound of both internal jugular veins in 1912 patients who received an implantable venous access port from August 2013 to January 2016. Among them, 106 patients showed loss of normal Doppler waveforms of the LIJV (56 men and 50 women; mean age, 61.4 ± 11.6 years). We retrospectively analyzed the presence and causes of the LBCV steno-occlusive lesions on contrast-enhanced chest computed tomography (CT) images. Results LBCV steno-occlusive lesions were present in 82 patients (77.4%). The causes of these lesions were anatomic structures (n = 70, 85.4%), tumorous lesions (n = 11, 13.4%), and thrombus (n = 1, 1.2%). The anterior anatomic structures to the LBCV causing stenosis were bony structures (n = 50), right upper lobe (n = 11), and mediastinal fat (n = 9). The posterior anatomic structures to the LBCV resulting in stenosis were right brachiocephalic artery (n = 58), left common carotid artery (n = 7), and aortic arch (n = 5). The tumorous lesions resulting in stenosis were mediastinal lymph node (n = 5), thymic lesions (n = 3), lymphoma (n = 1), lung cancer (n = 1), and bone tumor (n = 1). Conclusions It is necessary to suspect steno-occlusive lesion of the LBCV from various causes and to use caution when performing central venous catheterization in cases with loss of a normal Doppler waveform.

Left Internal Jugular Vein

A 60-year-old woman with neurofibromatosis type 1 presented with a nonpainful swelling in the left laterocervical region that had suddenly arisen after mild exertion the previous evening. Computed tomography with and without contrast enhancement revealed a rupture of the wall of the left internal jugular vein, with a diffuse subcutaneous hematoma. Postoperative histopathologic examination reported diffuse proliferation of plexiform neurofibromatous tissue within the vessel wall.
