  OBJECTIVE: Nonthrombotic pulmonary embolism (NTPE) encompasses a diverse group of rare but clinically significant conditions that involve fat, tumor, air, amniotic fluid, septic, parasitic, and iatrogenic emboli. This review summarizes the pathophysiology, imaging findings, and differential diagnoses of NTPE toward the goal of facilitating its accurate radiologic diagnosis. CONTENT: In NTPE, the use of computed tomography pulmonary angiography (CTPA) may reveal filling defects in the pulmonary arteries; however, the embolus is often not directly visualized, especially in cases of microscopic emboli. NTPE-related pulmonary lesions arise from two mechanisms: mechanical obstruction and chemical injury. Clarifying the link between these mechanisms and imaging features is crucial for achieving the accurate diagnosis of NTPEs. Tools such as dual-energy CT and ventilation-perfusion scintigraphy contribute to the detection of microvascular involvement. We present the characteristic imaging patterns and diagnostic pitfalls for each NTPE subtype, illustrated with representative cases. CONCLUSION: The awareness of NTPE entities and their imaging features is essential for the timely diagnosis and management of these emboli. Radiologists should consider the possible presence of an NTPE in patients with unexplained respiratory symptoms, especially when conventional imaging fails to demonstrate thrombotic emboli.

  BACKGROUND: Intra-arterial chemotherapy (IAC) can be highly effective for advanced head and neck cancers but often necessitates complex procedures and prolonged hospitalization. Herein, we demonstrate the utility of the repeatable microcatheter access port (ReMAP) system for streamlining IAC. METHODS: Two patients with advanced head and neck cancers underwent repeated IAC via a subcutaneously implanted ReMAP. Procedural feasibility, safety, and clinical outcomes were assessed and compared to conventional techniques. RESULTS: Case 1 involved a 42-year-old male with advanced maxillary sinus carcinoma who received eight IAC sessions of high-dose cisplatin without complications. Follow-up imaging confirmed complete tumor resolution. Case 2 was a 52-year-old female with primary intraosseous squamous cell carcinoma of the jaw who completed eight IAC sessions via an external carotid arterial sheath, then four sessions with the ReMAP, reducing inpatient requirements, and achieving tumor control. CONCLUSIONS: The ReMAP system enabled safe and effective IAC administration while reducing patient burden.
