Craniocervical junction haemangioblastoma

Case contributed by Dr Henry Knipe

Presentation

Transferred from peripheral hospital for investigation of left C2-T1 sensory changes.

Patient Data

Age: 55 years old
Gender: Female
Modality: MRI

Cervical cord is diffusely expanded to the level of C7-T1 with high T2 signal centrally. Small syrinx present, which only extends to C3-4. A cystic/solid mass is present at the craniocervical junction. 

Modality: MRI

Post contrast images demonstrate the mass has an enhaning nodule and a non-enhancing cystic component. 

Modality: MRI

Cystic/solid mass located posteriorly at the craniocervical junction. Larger non-enhancing cystic component which is present anterosuperiorly with a small and intensely enhancing nodule located posteroinferiorly. Cystic component appears intra-axial and separate from the fourth ventricle. The location of the solid nodule is less clear and may be intra-axial with a large eccentric component, or alternatively extra-axial in location posterior to the medulla. No prominent T2 flow voids, susceptibility artefact or diffusion restriction. Medulla is compressed anteriorly with effacement of the premedullary cistern. Abnormal T2 signal throughout the medulla extending into the pons and middle cerebellar peduncles bilaterally. 

Histopathology

MACROSCOPIC DESCRIPTION: "Brain tumour": Dusky purple nodule 14x10x7mm with haemorrhagic homogeneous cut surface.

MICROSCOPIC DESCRIPTION: The sections show a well-demarcated nodular tumour with scattered stromal cells in a background of many capillary-sized blood vessels. The tumour cells have mildly enlarged nuclei with hyperchromasia and foamy vacuolated cytoplasm. Mitoses are inconspicuous. There is no necrosis. The features are those of haemangioblastoma. There is no evidence of malignancy. Immunostains are to follow.

DIAGNOSIS: Brain tumour: Haemangioblastoma (WHO Grade I).

Case Discussion

Although the location is unusual (and probably arises from the medulla), the imaging features are fairly typical for haemangioblastoma, with the only characteristic feature lacking being prominent T2 flow voids.
