Congenital tibial pseudarthrosis: A challenge in pediatric radiology.

Congenital pseudarthrosis of the tibia (CPT) is a rare disorder affecting the skeletal system in pediatric population with an estimated incidence of 1:140,000 to 1:250,000 newborns. It is characterized by deformity of the tibia, including anterolateral bowing of the bone diaphysis and/or narrowing of the medullary canal, leading to instability or fracture. CPT can be either idiopathic or associated with underlying conditions such as type 1 neurofibromatosis (NF1), fibrous dysplasia, or Campanacci's osteofibrous dysplasia.

Gunshot vaginal trauma.

Nonobstetric vaginal or vulva trauma is an extremely rare occurrence, with an incidence of < 0.2% of traumas CT represents the gold standard in the diagnosis of gunshot lesions due to its ability to detect and stage injuries with very high sensitivity and specificity. A standardized protocol for penetrating trauma is still under debate for the use of intravenous contrast only or also rectal and oral contrast.

Basal ganglia calcification: a Fahr's disease case report.

Idiopathic basal ganglia calcification (IBGC), known as Fahr's disease, is a rare neurological disorder characterized by metabolic, biochemical, neuroradiological and neuropsychiatric alterations caused by symmetrical and bilateral intracranial calcifications. The disease has, in most cases, an autosomal dominant pattern of inheritance and genetic heterogeneity. Overlap of neuropsychiatric symptoms is common with movement disorders accounted for 55% of the manifestation.
