Pineal Parenchymal Tumor of Intermediate Differentiation with Gangliocytic Differentiation
A 49-year-old man presented with an extremely rare case of pineal parenchymal tumor with gangliocytic cells, manifesting as progressive gait disturbance and urinary incontinence lasting for one year. Brain MRI revealed a homogenously enhancing mass, measuring 3.5×2.7 ×1.7 cm, in the pineal body. The mass compressed the deep cerebral vein with superior displacement, which caused mild obstructive...

متن کاملEndoscopic Third Ventriculostomy and CyberKnife Radiosurgery of a Pineal Parenchymal Tumor of Intermediate Differentiation
We present a case of an 82-year-old female with a pineal parenchymal tumor of intermediate differentiation (PPTID). She underwent endoscopic third ventriculostomy and endoscopic biopsy of the tumor with resolution of her presenting symptoms. Because of her age and comorbidities, she was treated with CyberKnife stereotactic radiosurgery. This is the oldest patient with PPTID that has been report...
متن کاملStereotactic radiosurgery as a primary treatment modality for pineal parenchymal tumors
Background: Pineal parenchymal tumor (PPT) is extremely rare and histologically heterogeneous, and the optimal treatment strategy is controversial. This study examined clinical outcomes of patients with PPT treated with cyberknife radiosurgery (CKRS) as a primary treatment modality after tumor biopsy. Materials and Methods: Between 2009 and 2018, there were six patients diagnosed with PPT who w...
متن کاملIsochromosome 12p-positive pineal germ cell tumor.
We report the chromosomal characteristics of a recurrent pineal non-seminomatous germ cell tumor in a 16-year-old male patient. This non-seminomatous tumor had the following components: embryonal carcinoma, teratoma, yolk sac tumor, and trophoblastic giant cells. Chromosome analysis showed a near-triploid karyotype (64 chromosomes), including two copies of an isochromosome 12p. This latter find...
