Case Report:
Levoatriocardinal Vein: An Unusual Cause of Right-to-Left Shunting
Nilima Shet, Pierre Maldjian
J Clin Imaging Sci
2014, 4:68 (29 November 2014)
DOI
:10.4103/2156-7514.145907
PMID
:25558435
We present a case demonstrating an anomalous vessel connecting the left brachiocephalic vein and the left superior pulmonary vein, found incidentally on computed tomography (CT) imaging. This pulmonary-systemic venous connection, known as a levoatriocardinal vein, is a rare anomaly. In previous descriptions, this vessel has typically been associated with left-to-right shunt. Here, we describe the magnetic resonance imaging (MRI) and CT findings in a case with right-to-left shunting through the anomalous vessel likely secondary to elevated right cardiac pressure.

Management of Bleeding Duodenal Varices with Combined TIPS Decompression and Trans-TIPS Transvenous Obliteration Utilizing 3% Sodium Tetradecyl Sulfate Foam Sclerosis
Wael E Saad, Allison Lippert, Sandra Schwaner, Abdullah Al-Osaimi, Saher Sabri, Nael Saad

PMID

Objectives:
Endoscopic experience in the management of duodenal varices (DVs) is limited and challenging given the anatomic constraints and limited experience. The endovascular management of DVs is not yet established and the controversy of whether to manage them by decompression with a transjugular intrahepatic portosystemic shunt (TIPS) or by transvenous obliteration is unresolved. In the literature, the 6-12 month rebleeding rate of DVs after TIPS is 21-37% and after transvenous obliteration is 13%. The purpose of the study is to evaluate the clinical outcome of combined TIPS decompression and transvenous obliteration/sclerosis.
Materials and Methods:
This is a retrospective study (case series) of two institutions, evaluating patients who underwent TIPS and/or transvenous obliteration/sclerosis for bleeding DVs (from January 2009 to June 2013). TIPS was performed according to a standard procedure using covered stents. Transvenous obliteration (variceal sclerosis) from the systemic and/or portal venous circulation was performed utilizing 3% sodium tetradecyl sulfate foam. Transvenous obliteration was commonly augmented with coils and/or vascular plugs. Technical (technical success of establishing TIPS and completely obliterating the DVs) and clinical outcomes (rebleeding rate and survival) were evaluated.
Results:
Five patients with liver cirrhosis presenting with bleeding DVs were included in the study with all eventually (and coincidentally) receiving TIPS and transvenous obliteration. Two of the five patients underwent concomitant TIPS and transvenous obliteration in the same procedural setting. However, three patients underwent transvenous obliteration due to bleeding despite a patent TIPS that had been previously placed. The average time from TIPS placement to transvenous obliteration was 125 days (range: 3-324 days). After having both procedures, there was no rebleeding in the patients during a mean follow-up period of 22 months (6-50 months). Coils and/or metallic vascular plugs were used to augment the sclerosant obliteration in four of five patients.
Conclusion:
The combination of TIPS decompression and foam sclerosant transvenous obliteration appears to be effective in preventing rebleeding in this limited case series and compares favorably with the existing evidence for either approach [TIPS or balloon-occluded retrograde transvenous obliteration (BRTO)] alone.

Case Report:
A Rare Case of Aneurysm of Arc of Riolan Artery and Gastroduodenal Artery
Athiyappan Kumaresh, Ramachandran Rajoo, Sellappan Rajamanickam Babu, Subramanian Ilanchezhian
J Clin Imaging Sci
2014, 4:66 (29 November 2014)
DOI

PMID
:25558433
Arc of Riolan is a collateral channel that connects the proximal superior mesenteric artery (SMA) or its middle colic branch and the proximal inferior mesenteric artery or its left colic branch in case of stenosis of either of the arteries. A 65-year-old diabetic female presented with vague abdominal pain. Ultrasonography showed a large aneurysm within the abdomen in the left lumbar region. Computed tomography (CT) angiography done showed severe diffuse atherosclerotic calcification of the abdominal aorta with complete occlusion of the celiac trunk and mild stenosis of SMA origin. The arc of Riolan was seen between the middle colic artery and the ascending branch of the left colic artery, with a large saccular aneurysm in its mid section. No evidence of rupture or hematoma was visible. Another saccular aneurysm was also seen involving the gastro-duodenal and the pancreatico-duodenal collateral arcade. As far as we know, this is the first case of arc of Riolan artery aneurysm to be reported in English literature.

Imaging of Unilateral Meningo-ophthalmic Artery Anomaly in a Patient with Bilateral Nasopharyngeal Angiofibroma
Louise Louw, Johan Steyl, Eugene Loggenberg
J Clin Imaging Sci
2014, 4:65 (29 November 2014)
DOI

PMID
:25558432
A 12-year-old boy with epistaxis presented with a rare midline nasopharyngeal angiofibroma that extended lateral into the pterygoid and infratemporal fossae. Pre-operative angiography revealed bilateral prominent feeder arteries and two major anastomotic connections, and a rare left meningo-ophthalmic artery (M-OA) anomaly that was the sole path of supply to the eye. A literature search using Pubmed and Medline was conducted. For imaging, a six-vessel study (i.e. external and internal carotid and vertebral arteries on both sides) was selected. Embolization of prominent tumor feeder arteries was unsafe for tumor extirpation, but super-selective embolization of both sphenopalatine arteries was performed to control epistaxis. The M-OA anomaly that originated from the maxillary artery (MA) was marked by an ophthalmic artery (OA) variant with orbital and ocular divisions that coursed through the superior orbital fissure and optic foramen, respectively, each with distinct branching patterns, a middle meningeal artery (MMA) with normal branches (i.e. anterior and posterior branches), and two branch variations (i.e. lacrimal and meningeal branches) that originated from the anterior branch of the MMA. The lacrimal branch coursed through a cranio-orbital foramen, but the meningeal branch remained outside the orbit. The anatomy of the right OA was normal. The left M-OA anomaly was considered incidental and not tumor-related since the tumor was more prominent on the right side, and no intra-orbital infiltrations occurred. Of clinical significance is that proximal embolization of MA or MMA carries a high risk of visual impairment in cases where M-OA anomalies are the sole mode of supply to the eye.

Dedicated Breast CT: Feasibility for Monitoring Neoadjuvant Chemotherapy Treatment
Srinivasan Vedantham, Avice M O'Connell, Linxi Shi, Andrew Karellas, Alissa J Huston, Kristin A Skinner
J Clin Imaging Sci
2014, 4:64 (29 November 2014)
DOI
:10.4103/2156-7514.145867
PMID
:25558431
Objectives:
In this prospective pilot study, the feasibility of non-contrast dedicated breast computed tomography (bCT) to determine primary tumor volume and monitor its changes during neoadjuvant chemotherapy (NAC) treatment was investigated.
Materials and Methods:
Eleven women who underwent NAC were imaged with a clinical prototype dedicated bCT system at three time points - pre-, mid-, and post-treatment. The study radiologist marked the boundary of the primary tumor from which the tumor volume was quantified. An automated algorithm was developed to quantify the primary tumor volume for comparison with radiologist's segmentation. The correlation between pre-treatment tumor volumes from bCT and MRI, and the correlation and concordance in tumor size between post-treatment bCT and pathology were determined.
Results:
Tumor volumes from automated and radiologist's segmentations were correlated (Pearson's
r
= 0.935,
P
< 0.001) and were not different over all time points [
P
= 0.808, repeated measures analysis of variance (ANOVA)]. Pre-treatment tumor volumes from MRI and bCT were correlated (
r
= 0.905,
P
< 0.001). Tumor size from post-treatment bCT was correlated with pathology (
r
= 0.987,
P
= 0.002) for invasive ductal carcinoma larger than 5 mm and the maximum difference in tumor size was 0.57 cm. The presence of biopsy clip (3 mm) limited the ability to accurately measure tumors smaller than 5 mm. All study participants were pathologically assessed to be responders, with three subjects experiencing complete pathologic response for invasive cancer and the reminder experiencing partial response. Compared to pre-treatment tumor volume, there was a statistically significant (
P
= 0.0003, paired
t
-test) reduction in tumor volume at mid-treatment observed with bCT, with an average tumor volume reduction of 47%.
Conclusions:
This pilot study suggests that dedicated non-contrast bCT has the potential to serve as an expedient imaging tool for monitoring tumor volume changes during NAC. Larger studies are needed in future.

Blood Pool Contrast-enhanced Magnetic Resonance Angiography with Correlation to Digital Subtraction Angiography: A Pictorial Review
Martha-Grace Knuttinen, Jillian Karow, Winnie Mar, Margaret Golden, Karen L Xie
J Clin Imaging Sci
2014, 4:63 (29 November 2014)

Magnetic resonance angiography (MRA) provides noninvasive visualization of the vascular supply of soft tissue masses and vascular pathology, without harmful radiation. This is important for planning an endovascular intervention, and helps to evaluate the efficiency and effectiveness of the treatment. MRA with conventional extracellular contrast agents relies on accurate contrast bolus timing, limiting the imaging window to first-pass arterial phase. The recently introduced blood pool contrast agent (BPCA), gadofosveset trisodium, reversibly binds to human serum albumin, resulting in increased T1 relaxivity and prolonged intravascular retention time, permitting both first-pass and steady-state phase high-resolution imaging. In our practice, high-quality MRA serves as a detailed "roadmap" for the needed endovascular intervention. Cases of aortoiliac occlusive disease, inferior vena cava thrombus, pelvic congestion syndrome, and lower extremity arteriovenous malformation are discussed in this article. MRA was acquired at 1.5 T with an 8-channel phased array coil after intravenous administration of gadofosveset (0.03 mmol/kg body weight), at the first-pass phase. In the steady-state, serial T1-weighted 3D spoiled gradient echo images were obtained with high resolution. All patients underwent digital subtraction angiography (DSA) and endovascular treatment. MRA and DSA findings of vascular anatomy and pathology are discussed and correlated. BPCA-enhanced MRA provides high-quality first-pass and steady-state vascular imaging. This could increase the diagnostic accuracy and create a detailed map for pre-intervention planning. Understanding the pharmacokinetics of BPCA and being familiar with the indications and technique of MRA are important for diagnosis and endovascular intervention.

Two Cases of Thyroid Metastasis from Head and Neck Squamous Cell Carcinoma Detected by FDG-PET/CT
Carina Mari Aparici, Aung Zaw Win
J Clin Imaging Sci
2014, 4:62 (29 November 2014)
DOI

PMID
:25558429
We present two cases of head and neck squamous cell carcinoma (SCC) metastasizing to the thyroid gland. This is the first report that shows (18) F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) images of tonsillar and supraglottic SCCs invading the thyroid gland. Alcohol and tobacco use are the two most important risk factors for head and neck cancers, but recently human papilloma virus (HPV) infection has become a significant risk factor in the United States. FDG-PET/CT is very useful for SCC staging/restaging and follow-up.

Management of Mucoepidermoid Carcinoma of the Palate Utilizing
18
F-FDG PET/CT
Sankaran Sudhakar, Raga Geethika Velugubantla, Swathi Erva, Sai kiran Chennoju
J Clin Imaging Sci

Salivary gland carcinomas are a clinically diverse group of neoplasms with histological patterns overlapping other tumors, thus complicating their diagnosis. Mucoepidermoid carcinoma (MEC), first described by Masson and Berger in 1924, is a well-recognized salivary gland neoplasm, accounting for 5-10% of all salivary gland tumors. MEC frequently involves the major salivary glands and is rarely seen involving the jaws. The biological behavior of MEC is usually more aggressive with higher nodal and metastatic status at the time of presentation, which notably reduces the survival rate. Hence, early and accurate diagnosis utilizing advanced imaging modalities can reduce its morbidity. The present case is a rare presentation of MEC involving the palate, where (18) F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) was utilized for diagnosis and treatment.
