Avapritinib and ripretinib have now been approved by the US FDA for platelet-derived growth factor alpha D842V-mutant and refractory gastrointestinal stromal tumor patients, respectively. Here we report five patients who have been on avapritinib under an expanded access program.

Tetralogy of Fallot, right aortic arch with isolated left subclavian artery: Rare synchronous triple occurrence!!!

We present a rare synchronous occurrence of tetralogy of Fallot, right aortic arch, and isolated left subclavian artery, highlighting potential clinical and therapeutic implications.

Kommerell's diverticulum: rare cause of unilateral vocal cord palsy.

Kommerell's diverticulum is a relatively rare congenital aortic arch anomaly. A 56-year-old man presented with complaint of gradually progressive hoarseness of voice since 6 months. Clinical examination revealed no evidence of palpable neck mass or cervical lymphadenopathy.

Inadvertent arterial placement of central venous catheter: salvage using endovascular treatment.

The frequency of placing a central venous catheter (CVC) has increased and it is often performed in emergency situation for venous access. During such an emergency and placing without imaging guidance, sometimes inadvertent placement of CVC in subclavian artery (SCA) can occur. We hereby describe an unusual case of successful endovascular management of inadvertently inserted CVC in SCA by covered stent graft placement along with proper clinical context to manage a case of misplaced venous catheter in left SCA.

Loeffler's endocarditis with isolated left ventricular involvement on cardiac MRI.

Loeffler endocarditis is an uncommon restrictive cardiomyopathy associated with eosinophilia and endomyocardial fibrosis causing diastolic restriction, predominantly involving the right ventricle. Cardiac MRI plays a crucial role in early detection of disease. Early disease usually responds well to corticosteroids.

Imaging findings in Erdheim-Chester disease: what every radiologist needs to know.

Erdheim-Chester disease (ECD) is a rare sporadic non-Langerhans cell histiocytic (LCH) proliferative disorder with systemic predilection. It usually affects adults in the 5-7 decades of life and has non-specific clinical manifestations. Its suspicion is often heralded by the presence of characteristic radiological findings and subsequently confirmed by demonstration of CD68-positive xanthogranulomatous infiltrates on histopathology.

Imaging in Sternal Tumours: A Pictorial Review.

The sternum is an uncommon site for neoplastic involvement and metastases are far commoner than primary neoplasms. Of the primary tumours, malignant lesions are more frequent than the benign lesions. Early diagnosis and treatment is prudent in such neoplasms not only to halt disease progression but also to prevent circulatory compromise resulting from the mass effect on the mediastinum.

Unravelling chloroma: review of imaging findings.

Chloroma refers to the extramedullary proliferation of immature myeloid precursors occurring in a gamut of myeloproliferative and myelodysplastic conditions; acute myeloid leukaemia being the commonest. With non-specific clinical and imaging manifestations, it runs a high risk of misdiagnosis which may significantly affect the outcome of an otherwise treatable lesion. Also with these lesions heralding impending blast crises, awareness of the imaging findings becomes imperative.
