Clinical Summary

a 39 y/o man with recurrent headache

 

Imaging Findings

Images demonstrate  high signal mass  posterior to optic tract on FLAIR &T2 W and low signal on T1 W that reveals   enhancement in postcontrast study.
Hydrocephaly and diffusion restriction is not visualized .

Final Diagnosis

Hypothalamic glioma

 

Discussion (Related Text)

Low grade glioma is an uncommon diagnosis. Patients are younger than those with high grade glioma and most commonly present with seizures. The diagnostic modality of choice is MRI. On MRI, low-grade gliomas usually appear as low signal on T1 weighted imaging and a well-defined area of high signal on T2, often with a more extensive abnormality than seen on CT. FLAIR sequences attenuate the signal from CSF and can better define peri-ventricular lesions. The ultimate behaviour of these tumours is not benign. The natural history is of serial accumulation of genetic abnormalities resulting in malignant transformation and, ultimately, death.
