A case of bladder exstrophy and thoracal intramedullary teratoma

Pediatric Intramedullary Teratomas

“…The most frequently encountered symptoms were weakness of the legs, sensory abnormalities, and refl ex abnormalities. Computed tomography is a sensitive method to diff erentiate tera tomas from other tumors, on the basis of the heterogeneity of the teratomatous contents as seen in our case [5,15,32] . Some authors reported the superiority of magnetic resonance imaging, compared with computed tomography [24] .…”

Persisting Cough as the Single Presenting Symptom of an Intrathoracic Tumor in a Nine-Month-Old Child with Adenovirus Airway Infection

“…Teratomas account for up to 2% of childhood tumors and are seen in approximately 1 in 30,000 live births [4]. They originate from primitive cells and usually represent all of the three germ layers: endoderm, ectoderm and mesoderm.…”

Intramedullary Teratomas: Two Case Reports and a Review of the Literature

“…From a clinical viewpoint, the characteristics of teratomas are no different from those of other slow-growth intramedullary tumours; their clinical history is usually lengthy and ingravescence is gradual; the topographical distribution of algesic, motor and sensory disorders is related to the site. Dys-raphic malformations such as spina bifida, diastematomyelia, and tethered cord are associated with teratomas in about 15 % of the cases [1,7,12,21,33,40,44,46,51].…”

“…It has an ovoid or roundish shape with sharp edges; as regards the structure of the lesion, the alterations in the signal are dishomogeneous due to the presence of different components; hyperintense areas on T 1 sequences tend to be hypointense on T 2 because of lipomatous tissue; Gd administration does not lead to enhancement. The removal of these tumours is usually subtotal; total removal was possible only in 12 [1,10,15,17,18,[26][27][28][45][46][47][48] of the 59 cases reported in the literature. The difficulty in achieving total removal is caused by the tenacious adhesion to the healthy medullary parenchyma of both the lipomatous and the fibrotic components.…”
