We report a case of brachial plexus birth palsy in an infant with the inability to move the left upper limb since birth. There was neither history of birth trauma nor any complications during delivery. Magnetic resonance imaging (MRI) of brachial plexus showed postganglionic injury with musculoskeletal abnormalities. The child underwent surgical repair of the plexus and is on physical rehabilitation. In this case report, we discuss the utility of a single MRI examination with an elaborate discussion on various MRI signs of brachial plexus injury including secondary musculoskeletal manifestations...

Superficial siderosis is the slow accumulation of hemosiderin on the pial surfaces of the brain and spinal cord. The most common cause of intracranial superficial siderosis is secondary to subarachnoid hemorrhage. Rarely, superficial siderosis can also be caused by tumors. Superficial siderosis presents clinically as hearing loss and gait instability that progressively worsen. The diagnosis is primarily made by magnetic resonance imaging; however, susceptibility-weighted imaging (SWI) and T2* gradient echo (GRE) sequences demonstrate the highest sensitivity in detecting this condition...

Qian Yu, Driss Raissi
Ice-ball fracture is a rare and often overlooked entity that may lead to intraprocedural hemorrhage after percutaneous cryoablation of renal masses. There is scant literature on ice-ball fractures associated with percutaneous renal cryoablation. Immediate recognition of the lightning bolt sign during intraprocedural computed tomography can help identify patients who may have developed this complication.

Pancreatic pseudocyst develops as a complication of both acute and chronic pancreatitis. Although the common location of pseudocyst is lesser sac, extension of pseudocyst can occur into mesentery, retroperitoneum, inguinal region, scrotum, liver, spleen, mediastinum, pleura, and lung. Extension of pseudocyst into psoas muscle and lumbar triangle is extremely rare. The development of pseudocyst in lumbar triangle is radiologically equivalent and further extension of Grey Turner's sign seen clinically in acute pancreatitis...

Pelvic pain presents a common diagnostic conundrum with a myriad of causes ranging from benign and trivial to malignant and emergent. We present a case where a mucinous neoplasm of the appendix acted as a mimic for tubular adnexal pathology on imaging. With the associated imaging findings on ultrasound, computed tomography, and magnetic resonance imaging, we wish to raise awareness of mucinous tumors of the appendix when tubular right adnexal pathology is present both in the presence of pelvic or abdominal pain or when noted incidentally...

Introduction: In a setting of living-donor liver transplant and patients undergoing extended hepatic resections for both primary and metastatic liver tumors, preoperative assessment of hepatic arterial anatomy is very important because of the risk of ischemic complications in the event of inadvertent injury to the arterial supply. Anatomical variations in hepatic arterial supply to the liver are very common and seen in nearly half the population. Identifying anomalous origin of segment 4 hepatic artery is vital since this vessel can cross the transection plane and can result in liver ischemia and liver failure...

Lower back pain (LBP) is one of the most common chief complaints encountered in primary care. Advanced imaging studies, including computerized tomography (CT) and magnetic resonance imaging (MRI), are frequently ordered in the setting of LBP. Structural abnormalities are commonly identified by CT and MRI in patients complaining of low back pain, however, these findings are also found in asymptomatic patients. In the past decade, multiple guidelines have been published to help providers identify patients in whom the use of advanced imaging is appropriate...

Congenital pulmonary artery anomalies are infrequent but given improved prenatal diagnosis and care, and neonatal surgical advances, over the past two decades are not uncommonly encountered by cardiothoracic imagers. An understanding of their etiology, classifications, associated anomalies, and surgical management can be helpful to avoid under or overdiagnosis. Timely diagnosis assisted by familiarity with imaging findings across modalities and recognition of surgical findings allows for medical management and surgical planning for these patients, with more patients reaching adulthood than ever before...

Digital breast tomosynthesis (DBT) has become an important tool in breast imaging. It decreases the call-back rate while increasing the cancer detection rate on screening mammography and is useful for diagnostic examination of noncalcified lesions and for the evaluation of patients presenting with clinical symptoms. Management challenges and dilemmas that are encountered with abnormalities detected on DBT and lacking a sonographic correlate can now be addressed with tomosynthesis-guided core biopsy.

Background: Linear atelectasis is a focal area of subsegmental atelectasis with a linear shape. Linear atelectasis may occur as a consequence of subsegmental bronchial obstruction. Aims: We propose an early roentgen sign of obstructing lung tumors, namely perihilar linear atelectasis, and ascertain whether this phenomenon could be used as a sign to detect radiographically occult primary lung cancer. Materials and Methods: We performed a retrospective review of 45,000 posteroanterior chest radiographs to determine the frequency of appearance and characteristics of perihilar linear atelectasis...

Large vallecular masses are an uncommon disease entity which includes a wide spectrum of rare pathologies. These masses may present as purely vallecular in location or appear as an extension from adjacent anatomical sites like tongue base including lingual tonsils, epiglottis, palatine tonsils, epiglottis, and the remainder of supraglottis. Literature review reveals very rare conditions presenting as vallecular mass lesions. The imaging features are generally diagnostic for characterization. However, these masses can exhibit indeterminate appearance at imaging...

Internal abdominal hernias are rarely reported in the literature and have a very low rate of preoperative diagnosis. It is even rarer that they present with jaundice. A 59-year-old Caucasian female presented with a short history of jaundice, dark urine, epigastric pain, vomiting, and obstipation. Her liver biochemistry profile revealed a mixed cholestatic/hepatocellular pattern with significantly elevated bilirubin. She urgently underwent abdominal imaging which provided a preoperative diagnosis of internal herniation of the cecum within the lesser sac through the foramen of Winslow...

Context: Skull base venous anatomy. Aims: While prior studies have focused on the efficacy of conventional fluoroscopic venography and multidetector computed tomography venography to evaluate the inferior petrosal sinus (IPS) before image-guided intervention (such as dural venous sinus sampling), we believe that routine magnetic resonance imaging (MRI) may provide reliable structural information helpful for planning without the need for further imaging. Settings and Design: Retrospective review of brain MRI...

The process of abnormal reparative or reactive processes in the abdominal cavity, can lead to sclerosis and fibrous deposition. The relatively recent discovery of an IgG4 subgroup of immune mediated sclerosing disease 1,2 has thrown some light on the pathophysiology of these conditions. Firstly, our pictorial review aims to describe imaging findings to enhance the general radiologist's recognition and interpretation of this varied group of benign sclerotic and fibrotic abdominal processes. Secondly, along with the imaging findings, we bring into discussion the potential mimics of these pathologic processes to minimise interpretational errors...

A case of left distal forearm and wrist osteolipoma in a 56 year old female is reported. The patient presented with a 3 year history of nontender left wrist mass. Radiographs demonstrated a lobulated mass of mixed low density and calcifications, not adjacent to and with no connection to underlying bone. Ultrasound showed a spheroid hyperechoic lesion with internal heterogeneity and rim of calcifications. Magnetic resonance imaging revealed a lesion with predominantly fat characteristics on T1 weighted and T2 weighted sequences, with rim of peripheral calcification and specks of internal calcification...
