    Role and importance of Doppler ultrasound in the diagnosis of pulmonary sequestration: Report of two adolescent cases
    (Soc Romana Ultrasonografe Medicina Biologie-Srumb, 2013) Buyukkaya, Ramazan; Buyukkaya, Ayla; Ilce, Zekariya; Erdogmus, Besir; Kucuk, Adem; Ozturk, Beyhan
    Pulmonary sequestration is a rare pulmonary parenchymal anomaly. The localization of the aberrant artery and its relation with sequestration are of importance in the process of diagnosis in the preoperative period. The feeding artery can be identified by color Doppler ultrasonography. We report two cases of pulmonary sequestration in two adolescents, aged 11 and 13 years old, and this report documents the use of in which color Doppler ultrasound demonstrated the abnormal feeding artery. Color Doppler ultrasonography, a noninvasive and radiation-free imaging modality should be considered in the diagnostic algorithm of pulmonary sequestration.

    Hypertrophy of the ligamentum flavum (LF) can reduce the diameter of the spinal canal posteriorly. Such stenosis may significantly compress the dural sac and nerve roots, resulting in symptoms, even without a bulging anulus fibrosus or herniated nucleus pulposus. We conducted an anatomical study to determine the influence of age and gender on the thickness of the LF at the lower lumbar levels using magnetic resonance imaging (MRI). The thickness of 1,280 ligaments was determined at the L4-L5 and L5-S1 levels from MRIs. We screened 320 patients (152 males [47.5%] and 168 females [52.5%]) between 21 and 82 years of age. There were no significant differences in LF thickness with respect to gender (P > 0.05). Age was not correlated with the thicknesses of the LF. The left LF at the L4-L5 and L5-S1 levels was significantly thicker than on the right side (P < 0.05). Furthermore, the LF thicknesses at L5-S1 bilaterally were significantly greater than on the corresponding sides at L4-L5 (P < 0.05). The LF is an important anatomical structure, which might cause low back or leg pain. Therefore, the thickness of the LF should be measured and evaluated carefully in the case of spinal stenosis.
