Left Subclavian Vein

Congenital vascular anomalies of the venous drainage in the chest affect both cardiac and non-cardiac structures. Collateral venous drainage from the left subclavian vein to the great cardiac vein is a rare venous drainage pattern. These anomalies present a diagnostic challenge. Multi-detector computed tomography (MDCT) is useful in the diagnosis and treatment planning of these clinically complex disorders. We present a case report of an 18-year-old Caucasian male who came to our institute for evaluation of venous drainage patterns to the heart. We describe the contrast technique of bilateral dual injection MDCT venography and the imaging features of the venous drainage patterns to the heart.

ABSTRACT Background/Object: The ligation and transection of anterior third of superior sagittal sinus (AT-SSS) is an important step to approach anterior skull base lesions. Some clinical studies have shown frontal lobe venous infarct following such surgical procedures questioning the safety of its ligation. We have studied the variations in venous drainage patterns to AT-SSS in the normal population using postcontrast magnetic resonance venogram (MRV). A novel scoring system to recognize the subgroup with dominant venous drainage from frontal lobes has been described. Materials and Methods: In this study, 60 three-dimensional contrast-enhanced (CE) MRVs were obtained from those cases being evaluated for a headache not harboring any intracranial mass lesion. The AT-SSS with all its draining veins was studied in detail. Morphology of individual veins such as length, caliber, tributaries, and angulation with AT-SSS was studied, and a numerical value of 0 or 1 was assigned for each of the above parameters. Summing up these scores derived from the individual cortical veins quantified the drainage of AT-SSS. Results: There are 3–4 veins on either side draining to AT-SSS. Barely, 3% of the veins had > 3 tributaries. Only 6.6% of veins had a caliber >3 mm, and 16.5% drained at acute angles to AT-SSS. About 26% of the veins did cross at least half of the lateral frontal lobe. We found in 26 individuals the AT-SSS score was 0–2, in 22 it was 3–5 and, in only in 12 (20%) the score was 6 or more (dominant drainage). Conclusion: There are anatomical variations in venous drainage of frontal lobes into AT-SSS. Those with dominant drainage are likely to develop venous congestion and complications if sacrificed. It is possible to identify these individuals on the basis of venous drainage pattern as shown in CE-MRV.

Left Subclavian Vein

Without the femoral venous approach, transcatheter closure of an atrial septal defect is challenging. We performed percutaneous closure via the left subclavian vein in a patient with absence of the inferior vena cava with azygos continuation. Considering that inferior vena cava anomalies are not extremely rare among those with congenital heart disease, the left subclavian vein approach can be an alternative to the femoral approach.

Malignant Liver

Inflammatory myofibroblastic tumors (IMT) are a benign tumor entity, which rarely develop in the liver. Surgery is the most common treatment for these lesions as it is difficult to distinguish them from malignant liver tumors and local recurrent growth may occur. IMT is a diagnostic challenge for imaging. Only a limited number of reports of single cases or small number of patients described the imaging features on computed tomography. Reports on IMT appearance on magnetic resonance imaging are scarce. We present a case of IMT of the liver with infiltration of the abdominal wall treated with surgery and describe the imaging features with the use of the hepatobiliary contrast agent, gadoxetic acid (Gd-EOB).

Purpose. Thorough understanding of biliary anatomy is required when performing surgical interventions in the hepatobiliary system. This study describes the anatomical variations of right bile ducts in terms of branching and drainage patterns, and determines their frequency. Methods. We studied 73 samples of cadaveric material, focusing on the relationship of the right anterior and posterior segmental branches, the way they form the right hepatic duct, and the main variations of their drainage pattern. Results. The anatomy of the right hepatic duct was typical in 65.75% of samples. Ectopic drainage of the right anterior duct into the common hepatic duct was found in 15.07% and triple confluence in 9.59%. Ectopic drainage of the right posterior duct into the common hepatic duct was discovered in 2.74% and ectopic drainage of the right posterior duct into the left hepatic duct in 4.11%. Ectopic drainage of the right anterior duct into the left hepatic ductal system and ectopic drainage of the right posterior duct into the cystic duct was found in 1.37%. Conclusion. The branching pattern of the right hepatic duct was atypical in 34.25% of cases. Thus, knowledge of the anatomical variations of the extrahepatic bile ducts is important in many surgical cases.

Histopathologic Analysis

Leiomyomas of the kidney are rare, mostly occurring in adults as incidental findings, and are a diagnostic challenge. In a renal transplant recipient population, an increased risk of tumors is observed due to the effect of immunosuppressive drugs. A differential diagnosis between leiomyomas and other malignant lesions is not possible with current imaging methods. This report presents a case of a native kidney capsular leiomyoma in a kidney transplant recipient and highlights the features of computed tomography and contrast-enhanced ultrasound (CEUS), along with the histopathologic analysis. The CEUS and quantification studies are helpful in demonstrating the vascularization pattern of the renal capsular leiomyoma. This entity appearing with chronic kidney disease can resemble a renal cell carcinoma, in an otherwise healthy kidney. In this case, CEUS was useful for diagnosing the vascularization of the renal mass, although the pattern of intense vascularization could be diagnostically misleading, implying a malignant lesion. However, the pattern of enhancement due to CEUS showed no peculiarities that indicated histopathologic diagnosis.

Intracranial Dural Arteriovenous Fistulae

ABSTRACT:Background:Intracranial dural arteriovenous fistula with pial venous drainage may present with hemorrhage or focal neurologic deficit and may be difficult to treat. We wish to summarize the therapeutic approaches to these potentially dangerous lesions and to demonstrate how endovascular and neurosurgical therapies may have complimentary roles in their management.Methods:The clinical and radiological records of all patients who presented to our institution with intracranial dural arteriovenous fistula over the last 5 years were reviewed. In those cases demonstrating pial venous drainage, details of presentation, imaging features, endovascular and surgical therapy and outcome were analyzed.Results:We identified 13 patients with these lesions, 7 of whom presented with intracranial hemorrhage. Six patients were treated with embolization alone. Angiographic cure was achieved in 4. There was one complication in this group, a subarachnoid hemorrhage following glue injection. Four patients were treated with embolization followed by surgical occlusion of the pial venous drainage. Angiographic cure was achieved in all 4. There was one complication in this group, a facial nerve palsy following glue injection. Three patients were treated by surgery alone, with no complications and complete cure in all.Conclusion:Endovascular therapy of intracranial dural arteriovenous fistula may be curative but is often complex and carries definite risks. Neurosurgical ligation of pial draining veins, with pre-operative embolization when safe, may be a relatively more controlled method to achieve complete cure.

Different patterns of variations in the venous drainage have been observed in the past. During routine dissection in our Department of Anatomy, an unusual drainage pattern of the veins of the left side of the face of a middle aged cadaver was observed. The facial vein presented a normal course from its origin up to the base of mandible, and then it crossed the base of mandible posteriorly to the facial artery. Thereafter, it joined with the anterior division of retromandibular vein to form the common facial vein, which drained into the external jugular vein directly. Sound anatomic knowledge of the above variation in facial veins is essential to the success of surgical procedures in this region.

Diffuse infiltrating retinoblastoma (DIR) is characterized by absence of intraocular mass, lack of calcification. It may mimic inflammatory uveitis or exudative retinopathy. An eight-years-old boy presented with progressive loss of vision in left eye. Clinical evaluation revealed neovascular glaucoma with a yellow–gray fundal glow, exudative retinal detachment, subretinal exudation and telangiectatic vessels. The presentation was consistent with exudative retinopathy (Coat’s disease) but for the presence of a family history of retinoblastoma in the younger sibling. Despite the absence of an intraocular mass or calcification on multimodal imaging, the enucleation was done on the basis of clinical suspicion of retinoblastoma. Histopathology confirmed a diagnosis of DIR.: DIR can pose a diagnostic challenge due to its non-characteristic clinical and imaging features and atypical presentation. A high index of suspicion along with a positive family history was key to diagnosis in our case; histopathology was confirmatory.

Abstract Objective: To review the imaging features of granular cell tumors of the breast (on mammography, ultrasound, and magnetic resonance imaging), establishing a pathological correlation, in order to familiarize radiologists with this entity and make them aware of the differential diagnoses, other than malignancy, of lesions with spiculated margins. Materials and Methods: We reviewed the medical records (from a clinical-pathology database and picture archiving and communication system) of five patients with a pathologically confirmed diagnosis of granular cell tumor of the breast, treated at the Portuguese Oncology Institute of Lisbon, in the city of Lisbon, Portugal, between January 2012 and December 2018. Results: All five tumors exhibited imaging features highly suggestive of malignancy (BI-RADS 5 lesions), namely spiculated margins, significant depth, and posterior acoustic shadowing (on ultrasound). One tumor showed a kinetic curve indicative of washout on magnetic resonance imaging, two were adherent to the pectoralis muscle, and one was accompanied by skin retraction. Pathology provided the definitive diagnosis in all cases. Conclusion: Granular cell tumors of the breast pose a diagnostic challenge because they can present with clinical and imaging features mimicking malignancy, and the diagnosis is therefore provided by pathology. Radiologists should be familiarized with this entity, so they can be aware of the fact that breast lesions with spiculated margins can be indicative of diagnoses other than malignancy.
