Thrombogenic superior vena cava syndrome is an uncommon, dangerous complication of long-standing central venous catheter use. The increased use of central venous catheters has resulted in more non-malignant cases of superior vena cava syndrome across all age groups. We present a 5-year-old male with superior vena cava syndrome associated with acute onset of severe upper extremity and facial swelling, dyspnea, and a right subclavian central venous catheter malfunction. The patient was ultimately treated with percutaneous stenting of the superior vena cava with balloon-expandable Palmaz stents following unsuccessful angioplasty, catheter-directed thrombolysis, and percutaneous thrombectomy...

Uterine torsion is a rare condition which is part of a spectrum of gynecological emergencies. If diagnosis is delayed or the condition is left untreated, severe consequences such as infertility and life-threatening complications can arise. As presenting features are often non-specific and can be similar to commonly encountered gastrointestinal and urinary conditions, computed tomography is usually the first imaging modality utilized in an emergency setting. It is therefore important that the radiologist is familiar with recognizing computed tomography features of uterine torsion...

Bilal A Sethi, Jamie G Cooper
Pneumorrhachis, the presence of air in the spinal canal, is an unusual and alarming radiographic finding. The etiology is most commonly traumatic or iatrogenic but it can occur as a spontaneous phenomenon in association with pneumomediastinum. We report the case of a 16 year old male who presented with throat discomfort and a feeling of altered voice after recreational drug use. Examination confirmed widespread subcutaneous emphysema above the clavicles and plain radiograph and computed tomography imaging confirmed the presence of extensive pneumomediastinum and pneumorrhachis...

Apeksha Chaturvedi, Philip J Katzman, Arie Franco
We report the imaging appearances of a case of pathologically proven, neonatal neuroblastoma 4S with diffuse hepatic metastatic involvement at presentation. Patient had an abnormal appearing liver both by ultrasound and MR. There was no evidence for associated adrenal tumor by imaging. Lack of an associated adrenal mass led to initial misinterpretation of diffuse hepatic accumulation of MIBG seen with radionuclide scintigraphy. To the best our knowledge, this is the first report of metastatic neonatal 4S neuroblastoma without an adrenal (or extra-adrenal) primary identified either on pre- or post-natal imaging...

Sleeve gastrectomy is a relatively newer bariatric surgical procedure and has become the most common of all bariatric surgeries performed. Complication rates reported with sleeve gastrectomies are relatively low and are generally due to staple line leaks, hemorrhage, or sleeve stricture. Portal vein thrombosis is an uncommon but potentially dangerous complication. We present a case of a 21-year-old woman who developed thrombosis of the portal, splenic, and right common iliac veins that then resulted in multifocal brain abscesses from presumed Fusobacterium septic emboli following an uncomplicated laparoscopic sleeve gastrectomy...

Chordoma is a rare midline malignant tumor arising from embryonic remnants of the primitive notochord. The base of the skull is the second most common site of disease after the sacrococcygeal region. Intracranial chordoma constitutes about 30-35% of chordoma cases. Metastasis from chordoma is uncommon but if occurs, it tends to spread to the lungs. Cerebrospinal fluid seeding or drop metastasis is very rare. Here we describe a case of a clival chordoma with drop metastases.

Large septic pulmonary embolus is a rare finding in right-sided endocarditis. The entity represents a challenging diagnosis due to its variable and nonspecific clinical and radiological presentation and similarities with other conditions. We present a case of a 41 year-old woman who developed a large main pulmonary artery embolus and bilateral cavitary lung nodules in the setting of severe sepsis. Pulmonary artery exploration and clot retrieval ultimately revealed a large septic embolus from Streptococcus mutans native pulmonary valve endocarditis...

Intramural esophageal dissection is an uncommon condition, involving the separation of the esophageal mucosa from the muscular layers. To our knowledge, the temporal evolution of intramural esophageal dissection on computed tomography has not been previously demonstrated. We present a case of a 51-year-old male who first presented to the emergency department with fever, odynophagia, and dysphagia. He was treated for acute tonsillitis and discharged, but presented again after 10 days with worsening symptoms...

Dural arteriovenous fistulas (dAVf) are uncommon, acquired vascular lesions. Their location and vascular anatomy produces varied signs and symptoms and are misdiagnosed as other vascular anomalies. We present an atypical case of a dAVf identified along the left optic nerve sheath. The patient presented with progressive ophthalmological signs and was initially misdiagnosed with a left carotid-cavernous fistula. The aetiology, classification and treatment options are discussed.

This case report presents three cases of Meigs' syndrome: a benign ovarian tumor with ascites and a hydrothorax. After removal of the ovarian tumor, the symptoms resolved and the patients became asymptomatic. In daily practice, Meigs' syndrome is at first sight often mistaken for ovarian cancer. With this case report we would like to emphasize that the clinical presentation of an ovarian tumor might be ovarian cancer, but can masquerade as something uncommon like Meigs' syndrome. In a time span of two years we encountered three cases...

Laparoscopic Roux-en-Y gastric bypass has become the most common obesity surgery procedure worldwide over the last two decades. Many patients undergoing the procedure are women of reproductive age. This carries a risk for developing gastric bypass-related complications during pregnancy. One of the potentially serious risks is an internal hernia. We present a patient in the third trimester of pregnancy with an internal hernia following a laparoscopic Roux-en-Y gastric bypass for morbid obesity. We discuss the importance of computed tomography (CT) in the diagnosis of an internal hernia and review key CT findings including compression of the superior mesenteric vein, which proved to be crucial in diagnosing the internal hernia in this patient...

Homocystinuria is an inherited metabolic disorder most commonly caused by cystathionine β-synthase deficiency. Severe cases can cause white matter abnormalities that can mimic other vascular, toxic and metabolic disorders on computed tomography and magnetic resonance imaging. We present such a case which demonstrates not only extensive white matter abnormalities on magnetic resonance imaging, but also previously unreported basal ganglia signal abnormalities and imaging manifestations of increased intracranial pressure, likely caused by elevated methionine and betaine therapy...

Endometriomas can occur after any surgery where there is endometrial manipulation, and there are a number of reports of endometriomas developing in the abdominal wall at the site of the Pfannenstiel incision following Cesarean-section. Although this is ultimately a histopathologically-confirmed diagnosis, preoperative imaging including ultrasound, computed tomography, and magnetic resonance imaging may be helpful in the diagnosis and assessment. We report a pathology-confirmed case of Cesarean-section endometrioma with a classic, clinical presentation and imaging findings on computed tomography...

Pelvic kidney is a relatively common renal malformation as well as duplex kidney; however, the unilateral coexistence of these abnormalities is not frequently found. We present a case of a young woman with a history of hypertension in whom a pelvic and dysmorphic left kidney was discovered during ultrasound examination performed for the study of the renal arteries. Magnetic resonance imaging and computed tomography imaging revealed a duplex pelvic kidney. This combination is very rare; we have not found a similar case reported in the literature...

Paragangliomas are rare, mostly benign neuroendocrine tumors arising from autonomic paraganglia. Spinal paragangliomas are uncommon, and among these, paragangliomas of the thoracic spine are distinctly unusual. We present the case of a primary paraganglioma of the extradural thoracic spine in a 34-year-old woman.

We report a case of Propionibacterium acnes septic arthritis of a shoulder following two joint access procedures. Methodical investigation of these two procedures was performed using the Joint Commission root cause analysis matrix, which involved examination of protocols, interviews with technologists and physicians, and inspection of the procedure rooms and equipment. No procedural error or other causal factor for infection was found other than the injection through a five day-old tattoo during the first procedure...

Renal myxoma is a very rare benign neoplasm seen almost exclusively in adults with only 16 reported cases in the literature. All of these cases have been reported in native kidneys with none being reported in a transplant kidney. We report the case of a renal myxoma in a 17-year-old boy's transplant kidney that was found as an incidental mass on ultrasonography and further evaluated with CT and PET scans. PET findings of a renal myxoma are reported here for the first time, and imaging findings from previous cases are briefly reviewed...

We present a case of an 85-year-old patient who underwent clinical work-up for chronic heart failure, acute coronary syndrome, and pulmonary embolism, until she was diagnosed with a cardiac mass that was histologically identified as sarcoma. The aim of this educational case report is to raise awareness of cardiac masses and to point out diagnostic hints towards a cardiac tumor on chest X-ray, coronary angiography, echocardiography, and chest CT. Moreover, the vital role of cardiac magnetic resonance for the diagnosis of a cardiac mass is highlighted...

We report two patients with increased central skull base and craniocervical junction bone pneumatisation complicated by extra-osseous gas. One patient presented with symptoms of increasing nasal blockage and 'sinus pressure' on a background of extensive nasal polyposis. He was subsequently found to have a history of repeated Valsalva's manoeuvre, the cessation of which resulted in a rapid decrease in the amount of extra-osseous gas on imaging. The second patient presented following a minor head trauma with dysarthria from a hypoglossal nerve palsy and neck pain, with extensive intra- and extra-cranial gas including within the spinal canal (pneumorrhachis)...
