Multimodality imaging approach in a case of vascular toxicity caused by cabozantinib.

ABSTRACT: Vascular toxicity caused by cancer treatment can present as vasospasm, arterial thrombosis, and accelerated atherosclerosis. We report a case of a 60-year-old man with metastatic renal cell carcinoma under cabozantinib treatment for 3 years who presented to the hospital with relapsing episodes of rest angina. Due to the presence of ST depression in the 12-lead electrocardiogram and elevated troponin, a non-ST-segment elevation myocardial infarction was suspected. The patient underwent invasive coronary angiography, which revealed extended coronary artery spasm, and it subsided totally after nitrate administration. One year later, the patient presented again at the cardio-oncology outpatient clinic, reporting relapsing episodes of angina during the previous month. Coronary computed tomography angiography was performed, and it revealed 2 subsequent 70%-99% stenosis in OM1. To our knowledge, this is the first case of a patient treated with cabozantinib presenting with coronary artery spasm and accelerated atherosclerosis, in which a multimodality imaging approach was followed.

Project description:BackgroundSystemic light chain amyloidosis is a rare and debilitating disease, especially for which initially presented with digestive tract involvement. Myocardial amyloidosis is highly aggressive with generally poor prognosis and often resulted in missed diagnosis or misdiagnosis with routine examination tools. Multimodality imaging play an important role in diagnosing the amyloidosis effect on multiple organs. Chemoradiotherapy is the mainstay of treatment.Case presentationThis article presents a rare case of systemic light chain amyloidosis, initially with gastrointestinal symptoms, in a 68-year-old male. He was hospitalized with diarrhea for one year and a half, dysphagia for 4 months, but he had no dyspnea. The transthoracic echocardiogram revealed myocardial hypertrophy of the left ventricle, the hypertrophic heart muscle echoed like "ground glass". The left ventricular ejection fraction (LVEF) detected by Simpson method was 51% and global longitudinal strain (GLS) was -9.00%. But cardiac magnetic resonance showed the patient without gadolinium delayed enhancement. The urinary protein series quantification and the serum free light chain levels were all increased. While the ratio of free κ and free λ was decreased. Hence, the abdominal fat biopsy of the patient was amyloidosis by electronic and immunoelectron microscopy. Organs involved include heart, kidneys, gastrointestinal tract and nervous system, stage III of mayo 2012 model. The patient was treated with Dara-BCD chemotherapy. This case underscores the diagnostic complexity, emphasizing the need for early identification given the grim prognosis associated with systemic AL amyloidosis requiring clinical data, detailed imaging, and histopathological insights. After discharge, the patient became better and followed up in the outpatient.ConclusionsSystemic light chain amyloidosis can easily be missed diagnosis or misdiagnosis in its early stages, losing the opportunity for initiating earlier treatments to improve potential patient outcomes. Despite advancements in diagnostic biomarkers, this case highlights the potential for missed diagnosis with standard CMR imaging when gadolinium enhancement is negative. The utility of echocardiographic features such as reduced GLS and abnormal ECG findings emerges as critical in early identification of myocardial amyloidosis. The correct diagnosis of this case relied on the comprehensive utilization of multimodal imaging techniques including biopsy.
