“…Here, CEUS can effectively compensate for this by displaying the boundaries in real-time, distinguishing the parenchyma and the solid portion and necrotic areas within the mass, which further improves the success rate of puncture and diagnosis. [28,32,33] In addition to the occurrence of PTLD in the transplanted kidney, we also found 2 cases of PTLD in the native kidney after renal transplant with US records, [27] which indicated that while paying attention to transplanted kidneys, the native kidneys should also be monitored on a daily basis. Furthermore, when PTLD occurs in the central nervous system, gastrointestinal tract, lung, larynx, and cauda equina, [21,34,35] the role of the US is limited, and it should be combined with other imaging examinations such as computed tomographu, magnetic resonance imaging, and Positron emission tomography-computed tomography.…”

Rationale: Post-transplant lymphoproliferative disorder (PTLD) is a well-recognized, but uncommon complication in patients with kidney transplantation, which poses challenges in diagnosis and poor prognosis due to its low incidence and nonspecific clinical manifestations. As a routine follow-up examination method for kidney transplant patients, ultrasound (US) plays a significant role in the diagnosis of PTLD. Therefore, it is critical to evaluate the ultrasonic characteristics of PTLD in transplanted kidney patients for early detection and diagnosis. Patient concerns: A 59-year-old female patient was unexpectedly found with a mass in the hilum of the transplanted kidney 12th month after transplantation, which gradually grew up in the following 4 months. The latest US examination found hydronephrosis. Contrast-enhanced ultrasound (CEUS) demonstrated a hypo-enhancement pattern in arterial and parenchymal phases and showed a new irregular area lacking perceivable intensification within the mass, which was considered necrosis. Meanwhile, the patient developed an acute increase in serum creatinine from 122 to 195 μmol/L. Diagnosis: A US-guided biopsy was conducted with the final pathological diagnosis of PTLD (polymorphic). Interventions: After receiving 3 times of rituximab and symptomatic treatment, blood creatinine returned to normal but the mass was still progressing in the patient. Therefore, the treatment approach was modified to immune-chemotherapy. Outcomes: The patient was in a stable condition to date. Lessons: PTLD is a rare complication in a transplanted kidney. US and CEUS are the preferred imaging methods in renal transplant patients due to their good repeatability and no nephrotoxicity. This case demonstrates that continuous dynamic monitoring by using US and CEUS has significant value in the detection and diagnosis of PTLD in a transplanted kidney, suggesting early clinical intervention to avoid further progression.

“…Further studies with regard to morphological features and analyzation of microvascularization of the targeted lesions should be performed, especially with regard to the possibility of CEUS-guided US-CNB with the aim of an optimization of sample validity and the further reduction of repeat biopsies [32,[42][43][44][45].…”

BACKGROUND: Cervical lymphadenopathy can be benign or malignant. Its accurate diagnosis is necessary to determine appropriate treatment. Ultrasound-guided core needle biopsies (US-CNBs) are frequently used as a percutaneous sampling approach. OBJECTIVES: Our aim was to identify the efficacy and safety of US-CNBs in 125 patients with cervical lymphadenopathy and clinically suspected head and neck cancer during the COVID-19 pandemic with limited surgical resources. METHODS: US-CNBs of pathological lymph nodes were performed in 146 lymph nodes on 125 patients. Biopsies were performed ultrasound-guided with a reusable gun core biopsy system and a 10-cm-long 16-G needle. Standard of reference for the histological findings were panendoscopy, clinical and sonographic follow-up, surgical biopsy or a repeat US-CNB. RESULTS: Adequate material for histologic diagnosis was obtained in 111 patients (89%), of these 83 patients (75%) were diagnosed as malignant, whereas benign lymphadenopathy accounted for 28 patients (25%). Therefore, US-CNB was able to identify malignant or benign lymphadenopathy with an overall accuracy of 88% and 90%, respectively. CONCLUSIONS: Percutaneous US-CNB is a safe and effective alternative to surgical biopsy in the management of cervical lymphadenopathy in patients with clinically suspected head and neck cancer in a setting with limited resources.
