Ganglioneuroblastoma
Updates to Article Attributes
A ganglioneuroblastoma is a transitional tumour which lies on the intermediate spectrum of disease between a ganglioneuroma and a neuroblastoma.
Epidemiology
They are seen more commonly in children younger than 10 years. There is no definite gender predilection reported at the time of writing.
Pathology
The tumour contains elements of both malignant neuroblastoma and benign ganglioneuroma. They may be encapsulated.
Location
They are commonly attached to a nerve trunk.
Radiographic features
Imaging features can be variable and can range from a solid, well marginated-marginated, oblong paraspinous mass with homogeneous enhancement or as an irregular, cystic, poorly marginated-marginated, locally invasive-invasive mass with evidence of metastatic disease 2.
Plain radiograph
Non specific-specific but may hint to an initial diagnosis in larger lesions. May show a posterior retroperitoneal, mediastinal, or neck mass.
Ultrasound
Not a typical imaging modaalitymodality of choice but may show a heterogeneously echogenic lesion if able to be identified. Anechoic areas may be present corresponding to regions of haemorrhage and / or/or necrosis
CT
Variable and can range from homogeneous (especially small lesions) to heterogenous (large lesions).
MRI
Maybe be more useful in assesinhassesing intraspinal extension.
- T1: usually low signal intensity; haemorrhagic areas may manifest as areas of high signal
- T2: usually high signal intensity but heterogenous; cystic areas may be high signal.
- T1 C+: may show variable enhancement
Calcification may be difficult to detect at MR imaging; signal voids may be apparent.
