Myeloid sarcoma (MS), granulocytic sarcoma or chloroma, is defined as a localized extramedullary mass of blasts of granulocytic lineage with or without maturation, occurring outside the bone marrow. MS can be diagnosed concurrently with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). The authors report a case of sacral MS occurring as a relapse of myeloid leukemia in a 5-year-old girl who was taken to the emergency department with radiculopathy symptoms.

Geraldine Abbey-Mensah, Michael M Herskowitz, James Walsh, Robert F Leonardo
Splenic artery pseudoaneurysms (PSA) are rare entities and far less common than true aneurysms of the splenic artery. The most common etiology is pancreatitis, recurrent either in the setting of chronic pancreatitis or as an episode of acute pancreatitis. Less common causes include trauma, peptic ulcer disease, or iatrogenic causes. Almost all of the trauma-related case reports have been due to blunt trauma. We believe this to be the first reported case of a splenic artery PSA presenting with massive hematemesis at a significant time frame after penetrating trauma...

Tuan Phung, Thach Nguyen, Dung Tran, Nga Phan, Hung Nguyen
A 22-year-old woman with myasthenia gravis (MG) presented with ptosis and mild muscle weakness symptoms for one year. Computed tomography (CT) presented a diffuse bilobulate enlargement gland with a high density of soft tissue. Magnetic resonance imaging (MRI) showed the gland with no suppression on the opposed-phase chemical shift. After the thymic tumor diagnosis, she underwent thoracoscopic surgery for tumor resection. The postoperative histopathological finding was thymic lymphoid hyperplasia. This case suggests chemical shift MRI is not enough in distinguishing, and supplementary examination is essential to avoid unnecessary thymic biopsy and surgery...

Background: Hydatid cysts can be found in any organ. In adults, the liver and lungs are the most common locations; hydatid cysts in the pulmonary artery are rare. Clinical Case: We present the case of an 86-year-old female with a history of hepatic hydatid cyst since 2012, who presented with complaints of chronic productive cough, yellowish-green sputum, and dyspnea. CT and MRI showed multiseptate hydatid cysts in the right pulmonary artery.

Primary pulmonary lymphomas are rare with primary pulmonary non-Hodgkin lymphoma accounting for only 0.3% of primary lung neoplasms. Of these, the large majority are made up of marginal zone B-cell lymphoma and diffuse large B-cell lymphoma. We present a case of a very rare primary pulmonary anaplastic large cell lymphoma presenting as the luftsichel sign on chest radiograph. Pertinent imaging and pathology findings are discussed.

We report a case of 50-year-old man with a severe acute ischemic stroke followed by intracerebral hemorrhage and brain abscess due to systemic infection. His initial intracranial radiographic findings were normal but three days later MRI scan of the brain revealed well-defined rounded cystic lesion on the T2-weighted and T1-weighted images in the right basal ganglia; the lesion presented an area of diffusion restriction on DWI; lately the lesion was confirmed to be an early stage of cerebral abscess. A week later the patient was noted to have worsening neurological status and left extremity weakness, and emergency brain CT scan revealed massive intracerebral hemorrhage in the right occipital lobe; he underwent intracranial hematoma evacuation surgery...

Encephalitis is characterized by inflammation of brain tissue and has various infectious and noninfectious causes. CSF analysis and MRI usually reveal inflammatory changes although sometimes brain imaging may be normal. Autoimmune encephalitis is caused by antibodies against neuronal synaptic receptors, surface proteins, or intracellular proteins. In this case report, we present a 65-year-old female who presented with a fall and altered mental status. Workup for infectious etiologies was negative and MRI of the brain displayed focal restricted diffusion with corresponding T2-FLAIR hyperintensity involving gray matter structures, making the diagnosis unclear...

Paranasal sinus (PNS) foreign bodies are not common. They are usually due to penetrating trauma and iatrogenic events. On imaging, radiopaque foreign bodies can easily be detected by X-ray views of PNS. CT scan may be necessary to evaluate the exact location of foreign body in some cases. Foreign body in the PNS should be removed as early as possible. Approach and technique of its removal depend upon its size, shape, and location. Nasal endoscopic examination can be helpful for these cases. We present a pediatric girl case of penetrating FB injury inserted into the maxillary sinus towards nasopharynx in a suddenly braking car...

Rosai-Dorfman disease (RDD), also known as sinus histiocytosis with massive lymphadenopathy, is a rare nonmalignant lymphohistiocytic proliferative disorder. We report a patient with RDD who presented with multiple skin lesions, pulmonary involvement, and CT manifestations mimicking Langerhans cell histiocytosis, which improved after initiation of corticosteroid treatment.

Intravascular large B-cell lymphoma is a rare subtype of extranodal diffuse B-cell lymphoma characterized by proliferation of neoplastic cells within the lumen of small and medium sized vessels. Clinical and imaging findings are nebulous as the intravascular subtype of lymphoma can involve a multitude of organs. Involvement of the gallbladder is extremely uncommon, and imaging findings can be easily confused for more prevalent pathologies. We report a case of intravascular large B-cell lymphoma in an 83-year-old male and review clinical presentation and imaging findings on CT, ultrasound, hepatobiliary iminodiacetic acid (HIDA) scan, and MRI...

Although lung cancer has a high propensity for distant metastatic disease, penile metastases from primary lung neoplasms are considered particularly rare. A 71-year-old male presented to our hospital with a rapidly enlarging hard palpable penile mass. MR imaging demonstrated two penile masses centered in the left and right corpus cavernosa. Subsequent CT imaging revealed a spiculated pulmonary mass in the right upper lobe with PET/CT, MRI, and surgical exploration, demonstrating evidence of metastases to the left adrenal gland, right subscapularis muscle, brain, and small bowel...

Urethral duplication is a rare congenital malformation, especially in females. It may be associated with complex urogenital malformations, but the association with a cystic phallic urethra and a uterus didelphys is exceptional. We report a case of a newborn with urethral duplication, with the accessory urethra exteriorized by a large cyst, associated with a uterus didelphys and bone malformations. We discuss the clinical, radiographic, and therapeutic aspects as well as a literature review.

Mesenchymal chondrosarcoma (MCS) is a malignant cancer of the cartilage that accounts for less than 1% of all chondrosarcomas and typically occurs within the bone. One-third of all mesenchymal chondrosarcomas are extraosseous soft tissue sarcomas, rendering this as an uncommon entity. We report a rare case of an extraosseous chondrosarcoma with the cervical spinal canal in a 21-year-old male. The purpose of this case report is to discuss the imaging characteristics of this pathology proven diagnosis.

Urachal pathologies are rare and can mimic numerous abdominal and pelvic diseases. Differential diagnosis of urachal anomalies can be narrowed down by proper assessment of lesion location, morphology, imaging findings, patient demographics, and clinical history. We report a case of a 60-year-old male, with a history of unintentional weight loss without associated symptoms, who was diagnosed with locally invasive urachal adenocarcinoma. With this article, we pretend to emphasize urachal adenocarcinoma clinical features along with its key imaging findings with radiologic-pathologic correlation...

Focal Xanthogranulomatous pyelonephritis is a rare chronic inflammatory condition of kidneys which usually is associated with postrenal obstruction or renal stone leading to chronic bacterial infection and eventually chronic glomerular inflammation. About 90% of cases are of the diffuse type and associated with staghorn renal calculi. The case presented in this paper is of the focal type in a 58-year-old diabetic female. Interestingly she did not have symptoms or laboratory presentation of chronic renal bacterial infection except for elevated ESR...

Mucous plugs occur in a number of pulmonary conditions. Central right or left bronchus mucus plug causes complete pulmonary collapse making it an emergency life-threatening case. We describe the case of an 80-year-old man that, in postoperative period after a urological intervention, has had a progressive tachypnea and dyspnea during hospitalization for urological problems. Young surgeon on call was called.

Adenomatoid odontogenic tumor (AOT) is a rare noninvasive odontogenic tumor that occurs mostly in the second decade of life. Based on its tooth association, AOT can be classified into three categories of follicular, extrafollicular, and peripheral types; the follicular classification is considered as the most common type of AOT. This study reported a large extrafollicular case of AOT in a 40-year-old female. She was asymptomatic and tumor was detected accidentally by her dental practitioner. Since the panoramic radiograph showed a well-defined unilocular radiolucent lesion, we observed radiopaque spots within the lesion by using cone beam computed tomography...

Clinical radiological controls after the insertion of central venous catheters (CVC) are of high importance. Misplacement of the CVC, outside of large vessels, as described in our first case, occurs in more than 7% of cases and may be associated with life-threatening events. A persistent left-sided superior vena cava (PLSSVC) occurs in 0.3-0.5% of the standard population. In one of the cases a CT scan of the chest showed the catheter in a PLSSVC. Neoadjuvant radiochemotherapy was indicated in a patient with an adenocarcinoma of the oesophagus...

Neurofibromatosis type I (NF1) is a neurocutaneous disorder that involves autosomal dominant transmission. Skull defects, including sphenoid dysplasia and calvarial defects, are a rare finding in patients with NF1. Spinal meningocele and sphenoid wing dysplasia have been identified in NF1 but the occurrence of meningoceles at the skull base is extremely rare. A rare instance of jugular foramen meningocele being identified in an NF1 patient on imaging is described in this paper. To the best of our knowledge, only two such cases have been reported in the English literature...

Falciform ligament (remnant of umbilical vein) is an anatomical structure that connects the liver to the anterior abdominal wall. This case reports a rare clinical presentation of falciform ligament thrombosis as a consequence of acute gallstone pancreatitis, in a patient with noncirrhotic liver. A 55-year-old female with a history of cholelithiasis was admitted with abdominal pain. Biochemistry profile showed hyperamylasemia and deranged liver function tests. Computerized Tomography (CT) revealed a 3 cm attenuated structure that can be traced up to the left portal vein, which represents an acute thrombosis of the falciform ligament...
