“…Differentiation of malignant pediatric head and neck tumours from benign lesions and accurate definite diagnosis are essential for treatment planning as well as for prognosis of malignant tumours [1][2][3][4][5][6]. A variety of imaging techniques can help in characterization of pediatric head and neck masses.…”

We aimed to assess the clinical usefulness of the ADCs calculated from diffusion-weighted echo-planar MR images in the characterization of pediatric head and neck masses. This study included 78 pediatric patients (46 boys and 32 girls aged 3 months-15 years, mean 6 years) with head and neck mass. Routine MR imaging and diffusion-weighted MR imaging were done on a 1.5-T MR unit using a single-shot echo-planar imaging (EPI) with a b factor of 0.500 and 1,000 s mm(-2). The ADC value was calculated. The mean ADC values of the malignant tumours, benign solid masses and cystic lesions were (0.93 +/- 0.18) x 10(-3), (1.57 +/- 0.26) x 10(-3) and (2.01 +/- 0.21 ) x 10(-3) mm(2) s(-1), respectively. The difference in ADC value between the malignant tumours and benign lesions was statistically significant (p < 0.001). When an apparent diffusion coefficient value of 1.25 x 10(-3) mm(2) s(-1) was used as a threshold value for differentiating malignant from benign head and neck mass, the best results were obtained with an accuracy of 92.8%, sensitivity of 94.4%, specificity of 91.2%, positive predictive value of 91% and negative predictive value of 94.2%. Diffusion-weighted MR imaging is a new promising imaging approach that can be used for characterization of pediatric head and neck mass.

“…[2] Computed tomography (CT) and magnetic resonance imaging (MRI) provide essential information on the cyst location that allows optimal preoperative planning. [2] They are considered complementary, rather than competitive, modalities. [3] The advantages of MRI over CT in imaging other parts of body also apply to the neck, including better soft tissue resolution, lack of ionizing radiation and safer contrast agents.…”

Cystic lesions of the neck are usually diagnosed in infancy or childhood, but detection may be delayed until adulthood. The clinical manifestations combined with knowledge of the embryology and spatial anatomy of the head and neck often provide clues for a correct diagnosis. Ultrasound is frequently used initially to confirm the cystic nature of the lesion. Computed tomography and magnetic resonance imaging provide essential information on the cyst location that allows optimal preoperative planning.Keywords: Cystic lesion; imaging; neck.Cystic lesions of the neck are usually diagnosed in infancy or childhood, but detection may be delayed until adulthood. They often manifest as slow-growing masses and cause symptoms only after enlarging sufficiently or after infection. The clinical manifestations combined with knowledge of the embryology and spatial anatomy of the head and neck often provide clues for a correct diagnosis.[1] IMAGING MODALITYUltrasound is frequently used initially to confirm the cystic nature of the lesion.[2] Computed tomography (CT) and magnetic resonance imaging (MRI) provide essential information on the cyst location that allows optimal preoperative planning.[2] They are considered complementary, rather than competitive, modalities.[3] The advantages of MRI over CT in imaging other parts of body also apply to the neck, including better soft tissue resolution, lack of ionizing radiation and safer contrast agents.[3] By comparison CT examinations offer the advantages of superior assessment of osseous structures, shorter examination time, wider patient access and lower cost. ÖZBoynun kistik lezyonlarına genellikle süt çocukluğunda veya çocuklukta tanı konulur, fakat tespit erişkinliğe kadar gecikebilir. Baş ve boynun embriyoloji ve uzamsal anatomi bilgisi ile beraber klinik belirtiler çoğu zaman doğru bir tanı için ipuçları sağlar. Lezyonun kistik yapısını doğrulamak için ilk olarak sıklıkla ultrason kullanılır. Bilgisayarlı tomografi ve manyetik rezonans görüntüleme kist konumu hakkında gerekli bilgiyi sağlayarak ideal bir ameliyat öncesi planlamaya olanak verir.Anahtar Sözcükler: Kistik lezyon; görüntüleme; boyun.

A 5-year-old boy presented with a 4-day history of midline neck tenderness and swelling. Examination revealed a firm, palpable, mobile, erythematous midline neck mass that moved with tongue protrusion. Axial contrast-enhanced CT scan of the neck (CTDI Vol 12.76 mGy, Fig. 1) with sagittal reconstruction (Fig. 2) revealed a thick-walled, rim-enhancing, cystic midline mass (arrow) inferior to the hyoid bone and anterior to the normal thyroid gland.Thyroglossal duct cysts are the most common cause of midline neck masses. These can be found at any level from the base of the tongue to the isthmus of the thyroid gland.
