Scimitar syndrome, a rare congenital cardiopulmonary condition, presents in both pediatric and adult populations as an anomalous pulmonary venous return of most of the right lung to the inferior vena cava. Recently, asymptomatic adult cases have been diagnosed with advances in imaging studies. We report the case of an asymptomatic 43-year-old male, with a complex variant scimitar syndrome diagnosed by computed tomographic angiography.

This is the case of a twenty-two-year-old active duty male soldier with nonexertional chest pain and worsening performance on his physical fitness test. His history was significant for a diagnosis of dextrocardia upon entry to the military. On acute presentation to the emergency department, he was deemed a candidate for the expedited coronary computed tomographic angiography (CCTA) protocol to assess for a possible anatomic cause of his symptoms. CCTA revealed the presence of an anomalous right pulmonary vein draining into the inferior vena cava. Additionally, the imaging showed dextroversion of the heart, dilation of the inferior vena cava, right atrium, and right ventricle, as well as a hypoplastic right lung, a collection of findings consistent with scimitar syndrome and not dextrocardia.

This is a case report of a 35-year-old female pedestrian struck by a semi-truck. computed tomographic angiography (CTA) revealed a pseudoaneurysm at the proximal brachiocephalic artery measuring 1.8 cm in cranio-caudal length and 1.2 × 0.6 cm transverse. Just distal to the pseudoaneurysm, there was severe luminal narrowing caused by either a dissection flap or mural thrombus. Due to profound left-sided weakness, transcranial Doppler ultrasound was performed which demonstrated “hesitant” waveforms in the right middle cerebral and right vertebral arteries secondary to proximal obstruction. Hesitant waveforms display mid-systolic velocity deceleration and may also be referred to as the “bunny” waveform. Emboli monitoring of the right middle cerebral and basilar arteries were positive for active embolization

A 67-year-old woman had delayed initial diagnosis of her right low flow carotid cavernous fistula (CCF) during the coronavirus disease (COVID-19) pandemic due to difficulty detecting ocular signs via online virtual examinations. Her right eye conjunctival erythema and proptosis with medial rectus enlargement on computed tomography scan was initially misdiagnosed as euthyroid thyroid-associated orbitopathy without lid retraction. She developed vision loss, and increasing episcleral venous congestion and CCF was suspected. Computed tomographic angiography did not show an obvious fistula. Digital subtraction angiography revealed the right-sided low flow CCF, which was fed from vessels from the contralateral side.

With the use of sophisticated imaging modalities, congenital anomalies of the inferior vena cava and its tributaries, such as agenesis of the hepatic vena cava, are becoming more and more commonly encountered. Scimitar syndrome, also called venolobar syndrome and hypogenetic lung syndrome, is a rare pulmonary vascular anomaly of the right lung that can sometimes be associated with some cardiovascular anomalies. We present here a case with agenesis of the hepatic vena cava associated with scimitar syndrome.

Background: In the present article we present the characteristics of Eagle syndrome, which is an often overlooked cause of chronic pain in the neck and head. The syndrome is caused by the compression of an elongated styloid process on the adjacent cranial nerves or the carotid arteries. Since there are disparate data in the literature regarding the proportion of people with an elongated styloid process, we conducted a survey to determine the percentage of patients with an elongated styloid process in a group of subjects who underwent computed tomographic imaging of the neck vessels in our institution.Methods: We analyzed the images of 104 patients who were referred to our institution for computed tomographic angiography of the neck between the years 2014 and 2016. With the help of a software measurement tool, we determined the length of the styloid processes and compared the length of the processes on both sides and in both genders. Patients with an elongated styloid process were reviewed for any symptoms of Eagle syndrome.Results: The average age of the reviewed patients was 67.1 years. Both genders were equally represented (51 % men and 49 % women). The average length of the styloid process was 23.8 (7.0) mm, with 23 patients (22.1 %) having a styloid process longer than 30 mm. In one third of those patients the styloid process was elongated bilaterally. There were no differences in the average length of the styloid process between men and women and between the left and the right side. Among patients with an elongated styloid process, only one (4.3 %) had symptoms attributable to the Eagle syndrome.Conclusions: Eagle syndrome should be suspected in a patient with repetitive, dull pain in the throat and neck, which worsens during speaking, chewing or swallowing. The diagnosis is confirmed by computed tomography which could demonstrate an elongated styloid process and exclude other causes for neck pain. With regard to the results of our study, an elongated styloid process is found in a relatively high percentage of patients but the condition is only rarely symptomatic.

Congenital pulmonary venous anomalies are not uncommon that can occur either in isolation or in association with different forms of congenital heart disease. Clinical presentation of these anomalies may vary from the relatively benign single anomalous partial pulmonary venous return to life-threatening critical obstructed total anomalous pulmonary venous return. Accurate delineation of these anomalies and accompanied cardiovascular anomalies are crucial to guide decision making in these patients. Low-dose high-pitch dual-source 256-detector multidetector computed tomographic angiography is a fast and reliable imaging modality allowing comprehensive noninvasive anatomic imaging in neonates and children with congenital pulmonary venous anomalies with lower radiation doses and should be preferred for these patients after transthoracic echocardiography.

Pedicled mobile thrombus in the right atrium is an extremely rare condition. Here, we described a case of a 42-year-old male hospitalized with complaints of chest pain and hemoptysis. Computed tomographic angiography of the pulmonary artery showed signs of embolism, and thoracic echocardiography indicated a pedicled mobile cloudy echo in the right atrium, which was initially suspected to be a myxoma. However, it was confirmed to be a thrombus by histopathological examination. Postoperatively, the patient was treated with anticoagulant therapy comprising of low molecular heparin and warfarin, and the patient recovered well. Thoracic echocardiography performed 3 months after surgery ruled out any recurrence of right atrial thrombus.
