Fibrous Dysplasia Polyostotic: When Radiology Clarifies the Diagnosis.

Fibrous dysplasia is a rare non-hereditary congenital condition characterized by 2 main forms: monostotic and polyostotic. Monostotic is the more common form, while polyostotic, often associated with a syndrome, is rarer. The case presented involves a 10-year-old patient who was diagnosed with polyostotic fibrous dysplasia accompanied by an endocrinopathy. This report explores the clinical and radiological aspects of this condition based on the patient's case.

Amyand's hernia in a 3-month-old infant: A case report.

Amyand's hernia is a rare condition characterized by an inguinal hernia containing the appendix, which can lead to complications. It is more common in children and it can be challenging to diagnose due to its location, often being mistaken for other conditions like strangulated hernias, orchitis-epididymitis, or testicular torsion. Imaging, including computed tomography and sonography, plays an important role in diagnosis, which is usually made intraoperatively. A case concerning a 3-month-old boy with a large acute scrotum that had been evolving for 4 days was presented. Clinical examination revealed a hard inguinal mass and a large scrotum with signs of inflammation. An inguinoscrotal ultrasound found a herniated appendix, suggesting the diagnosis of Amyand's hernia, which was confirmed after surgery.

Mandibular Brown Tumor Revealing Hyperparathyroidism in a Patient With Neurofibromatosis Type I: Case Report.

The brown tumor is a non-neoplastic lesion resulting from an abnormality in bone metabolism in the context of primary, secondary, or tertiary hyperparathyroidism. They can affect any bone structure and be single or multiple. They are usually located on the long bones, pelvis, ribs, and collarbones. Facial localization is rare and is found in only 4.5% of brown tumors dominated by mandibular involvement. The treatment of a brown tumor depends on several elements: etiology, location, and symptomatology. It can regress or disappear after the treatment of hyperparathyroidism, thus avoiding surgical removal. Otherwise, excision of this mass is performed. We illustrate through this case a brown mandibular tumor revealing secondary hyperparathyroidism in a patient with a history of end-stage chronic renal failure on hemodialysis and associated neurofibromatosis type 1.
