Vesicourachal Diverticulum: An Uncommon Incidental Finding on Staging F-FDG PET/CT in a Patient with Suspected Malignant Transformation of Neurofibromatosis.

In a 32-y-old man with neurofibromatosis type 1, F-FDG PET/CT incidentally revealed a vesicourachal diverticulum, a rare anatomic variant. The PET/CT, performed for staging a malignant peripheral nerve sheath tumor, highlighted a distinctive F-FDG-avid pattern crucial for accurate diagnosis. Recognizing such features enhances disease assessment and clarifies distinctions between benign urogenital anomalies and malignancies in F-FDG PET/CT staging.

A comprehensive, multidisciplinary, precision medicine approach to discover effective therapy for an undiagnosed, progressive, fibroinflammatory disease.

Precision medicine has generated diagnoses for many patients with challenging undiagnosed disorders. Some individuals remain without a diagnosis despite comprehensive testing, and this impedes their treatment. This report addresses the role of personalized medicine in identifying effective therapy for an undiagnosed disease.
