[Four cases of ectopic pinealoma with ipsilateral cerebral hemiatrophy (author's transl)]. 1975

R Kwak, and J Suzuki

The 6 cases of brain tumor with ipsilateral cerebral hemiatrophy in which 4 cases were experienced in our institute and 2 cases were found in literature were studied in this paper. The specific character which was common in 6 cases were observed in their clinical course and the findings of clinical examinations. The histopathological study was proceeded with a autopsy case to observe the correlation between brain tumor and the ipsilateral cerebral hemiatrophy. As the result of it, we discussed the mechanism of appearance of the ipsilateral cerebral hemiatrophy due to brain tumor in the thalamic region. 1) All six cases were very young in which the age of onset was between 8 to 14 years old, 11 years 8 months old in average. 2) Their clinical course was relatively chronic. The period from onset to first admission was between 1 year 2 months to 4 years, 2 years and 1 month in average. 3) The declining of school work and hemiparesis were recognized as the primary sign of their onset. Main symptoms were hemiparesis, dementia, character and emotional change, and abnormal behavior, but sign of increased intracranial pressure was not observed. 4) The findings of carotid angiogram and pneumoence-phalogram showed ipsilateral hemiatrophy on the tumor side. 5) The brain tumor localized in the thalamic region and its surroundings which was common with all six cases. 6) Histopathological diagnosis was pinealoma, and 3 autopsy cases were ectopic pinealoma and the other 3 cases were suspected too as ectopic pinealoma. 7) In our autopsy case, ipsilateral cortical and subcortical atrophy with ectopic pinealoma was observed. As the pathological findins, degeneration and destruction of ganglion cells, demyelination in the subcortex and damage of axon were observed. These findings suggested that the ipsilateral cerebral hemiatrophy was induced by Waller's and retrograde degeneration as the result of the secondary damages of the thalamic ganglion cells and the afferent and efferent nerve fibers, due to invasive tumor into thalamic region.

D010871	Pinealoma	Neoplasms which originate from pineal parenchymal cells that tend to enlarge the gland and be locally invasive. The two major forms are pineocytoma and the more malignant pineoblastoma. Pineocytomas have moderate cellularity and tend to form rosette patterns. Pineoblastomas are highly cellular tumors containing small, poorly differentiated cells. These tumors occasionally seed the neuroaxis or cause obstructive HYDROCEPHALUS or Parinaud's syndrome. GERMINOMA; CARCINOMA, EMBRYONAL; GLIOMA; and other neoplasms may arise in the pineal region with germinoma being the most common pineal region tumor.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D001932	Brain Neoplasms	Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.

D006429	Hemiplegia	Severe or complete loss of motor function on one side of the body. This condition is usually caused by BRAIN DISEASES that are localized to the cerebral hemisphere opposite to the side of weakness. Less frequently, BRAIN STEM lesions; cervical SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; and other conditions may manifest as hemiplegia. The term hemiparesis (see PARESIS) refers to mild to moderate weakness involving one side of the body.
