Chronic lymphocytic leukemia (CLL) is the second most common hematologic malignancy, and it is characterized by lymphocytic leukocytosis and secondary hematologic deficiencies. While it most commonly presents as a systemic disease, extramedullary involvement may rarely occur. The literature surrounding CLL metastatic disease to the gallbladder is particularly sparse. Interestingly, we describe a case of a 67-year-old female who presented with painless jaundice and was found to have a rapidly growing gallbladder wall mass which was determined to be CLL metastatic disease after extensive surgical resection. It is important for radiologists to recognize the possibility of CLL metastatic disease to the gallbladder when evaluating potential cases of cholecystitis due to the overlapping spectrum of imaging findings. Cognizant radiologists can potentially save patients from surgical intervention as CLL is classically treated with chemotherapy.
A 37-year-old female was admitted with worsening neurologic function. On arrival from an outside hospital, the patient was obtunded and intubated. Magnetic resonance imaging of the brain revealed nodular enhancement of the leptomeninges, intracranial osteolytic lesions, and diffuse vasogenic edema causing mass effect. Imaging of the thoracic spine revealed pathologic compression fractures of 4 thoracic vertebrae. On review of the patient's electronic medical record, the patient had previously received treatment for secondary syphilis with intramuscular benzathine penicillin G. Surgical biopsies of the frontal bone and dura showed diffuse, chronic inflammation while a biopsy of the adjacent brain parenchyma revealed replicating spirochetes. The patient was subsequently prescribed dexamethasone and benzathine penicillin G. She regained neurologic function but later signed out against medical advice without completing her treatment regimen.
Approximately 13,500 children each year are treated for non-powder gun injuries of which approximately one-quarter of these injuries are puncture wounds. Although rare, vascular migration of the bullet or pellet (otherwise known as the “wandering bullet”) may result in downstream organ damage secondary to vascular or venous occlusion, most commonly travelling anterograde and lodging within the lung venous system. Interestingly, we present a case of a 12-year-old female who was shot in the neck with a compressed-air gun loaded with ball-bearing pellets. Eventual retrograde vascular migration of the ball-bearing pellet from the right internal jugular vein to the hepatic vein caused hepatic venous occlusion and congestion. It is important for radiologists to remember the possibility of retrograde travel of bullets and pellets, and radiographs should be scrutinized for foreign bodies present in areas other than the region of injury. Bullet retrieval is determined by clinical evaluation and necessity, and if indicated, endovascular, percutaneous retrieval, or surgical exploration may be considered.
Hepatic portal venous gas (HPVG) is a rare imaging finding in infants and usually indicative of a severe disease process such as necrotizing enterocolitis, bowel ischemia, or bowel wall rupture / infarction. The diagnosis of HPVG may have serious implications such as parenteral nutrition, antibiotics and even surgery. In this case, we present an 8-week-old male with a history of prematurity presenting with HPVG, later concluded to be caused by milk protein allergy. Milk protein allergy is a rare cause of HPVG, but it should be recognized due to its benignity and potential prevention of unnecessary testing and interventions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
