Final Diagnosis:
Right frontal lesion: gangliocytoma.
Based
The patient went on the histological features of the small amount of tissue provided, the appropriate diagnosis is gangliocytomato have a craniotomy and biopsy. This is an uncommon benign primary brain tumour.
Histology
Microscopic Description:
Sections show multiple small fragments of neuropil containing focal collections of atypical ganglion cell neurons. These cells have large round nuclei with prominent nucleoli, abundant cytoplasm and peripheral Nissl substance. The cells are atypical in their morphology, orientation and spacial arrangement. Many blood vessels are surrounded by small cuffs of reactive lymphocytes. The intervening neuropil shows a mild degree of reactive gliosis, occasional axonal steroids and multiple small calcified deposits, resembling psammoma bodies. There does not appear to be any neoplastic glial component to this lesion.
Final Diagnosis: gangliocytoma.
