Acute Febrile Neutrophilic Dermatosis after Deep Inferior Epigastric Perforator Flap Breast Reconstruction

anechoic and commaor mushroom-shaped unilocular on ultrasonography. In rare cases, it shows signs of a multilocular cystic mass with linear septa [3]. Although the CT scan showed the hydrocele of the canal of Nuck in the form of a homogenous fluidfilled unilocular cyst extending to the labia, its communication with the abdominal cavity could not be determined. MRI revealed well-defined, thinwalled, sausage-shaped cystic lesions in the hydrocele of the canal of Nuck. Lowand high-signal intensities were observed on the T1and T2-weighted images, respectively [2]. The final diagnosis was made during surgery and confirmed by histopathological examination. The standardized therapeutic approach is to surgically remove edema and to ligate the processus vaginalis peritonei. Due to the rarity of hydrocele of the canal of Nuck, there are no reports on the recurrence rate of masses or simultaneous occurrence on the opposite side. The hernial sac can include peritoneal fluid, omental fat, bowel loops, the ovary, the fallopian tube, or the urinary bladder in the inguinal canal. Therefore, surgeons can avoid causing damage in the process of examining the anatomy around the inguinal canal by using preoperative imaging. Despite the fact that hydrocele of the canal of Nuck occurs mainly in adolescence, we strongly suspected hydrocele of the canal of Nuck in this case based on the clinical symptoms and imaging diagnosis, and confirmed the diagnosis by surgical exploration without delay. This case suggests that hydrocele of the canal of Nuck should be included in the differential diagnosis of masses occurring in the inguinal area in adult females.
