From: Head and neck malignant lymphoma and squamous cell carcinoma discernment, is DWI conclusive?
A male patient, 52 years old, complaining of left sided neck swelling (proved pathologically as cervical lymphoma). A, B Axial T1- and T2-weighted image revealed multiple well-defined variable sized enlarged cervical lymph nodes (LNs) at the left side of the neck. The lesions appear isointense in T1WI and hyperintense signal in T2WI. C, D DW-MRI at b = 1000 s/mm2, the ADC map (mean ADC value = 0.63 × 10–3 mm2/s). E, F DW-MRI at b = 1500 s/mm2, the ADC map (mean ADC value = 0.60 × 10–3 mm2/s). G, H DW-MRI at b = 2000 s/mm2, the ADC map (mean ADC value = 0.55 × 10–3 mm2/s). The lesion is seen truly restricted on DWIs with notably low ADC values on the corresponding ADC maps with the lowest ADC value at b = 2000 s/mm2
