RFGLNet for adverse weather domain-generalized semantic segmentation with frequency low-rank enhancement - Nature

We present a case of a six-month-old female with a five-month history of right-sided torticollis that showed little improvement despite physical therapy. She presented to the emergency department due to parental concern for pneumonia, with congestion and cough without respiratory distress. Physical examination demonstrated leftward rotation and right lateral flexion of the head and cervical spine, consistent with the previously diagnosed right-sided torticollis. Chest radiographs were obtained in the workup for pneumonia and incidentally revealed segmentation anomalies of the cervical and upper thoracic spine as well as multiple bilateral bifid and fused ribs, more pronounced on the right. The radiographic findings were interpreted as highly suggestive of Klippel-Feil syndrome (KFS). In the setting of refractory torticollis and characteristic congenital vertebral abnormalities, the diagnosis of KFS was made. No acute complication requiring immediate intervention was documented. Referral to appropriate specialists was recommended for further evaluation and longitudinal management. This case highlights the importance of maintaining a broad differential diagnosis when evaluating refra
