We present a rare case of thalamic germinoma with crossed aphasia in a dextral. A patient, 17-year-old righat-handed male, was admitted to Nippon Medical School Hospital with chief complaints of headache, abnormality of visual field and speech disturbance. There were pigmentations on the back of hand, foot and the perineum. Neurological examination revealed left homonymous hemianopsia, right slight degree of ptosis, left facial palsy, a mild paresis of the left upper extremity and motor aphasia. Right carotid angiography showed marked unrolling and midline shift of right anterior cerebral artery. CT scan revealed ring-like high density area in the right thalamic region, which was enhanced after constant infusion. Brain scintigraphy also showed an abnormal accumulation at the same site. The hen-egg sized tumor of 40 g. weight was almost totally removed by the right fronto-parietal craniotomy. The tumor was characterized histologically by the so-called two cell pattern with teratomatous components. As postoperative treatment local injection of adriamycine, irradiation and immunotherapy with picibanil were performed, and then left hemiparesis was markedly improved without sign of recurrence. Language evaluation was performed after operation. There were dysarthria, remarkable word amnesia, paraphasia and perseveration. Repetition was also impaired. His speech function was concluded to be a mixed type aphasia mainly composed of Broca's aphasia. The speech function of thalamus and crossed aphasia with dextrales were discussed.

A 29-year-old man presented with diplopia, dysarthria, anisocoria, oculomotor nerve paralysis, abducens nerve paralysis, right facial palsy, and spastic hemiparetic gait. Magnetic resonance imaging (MRI) showed a homogenously enhanced mass in the midbrain. MRI-guided stereotactic biopsy was performed, and the histologic diagnosis was pure germinoma. The tumor disappeared after chemotherapy and radiotherapy. Germinoma should be included in the differential diagnosis of midbrain lesions in young adults. MRI-guided stereotactic biopsy provided a helpful diagnostic clue in a patient with a midbrain lesion.

Holmes' tremor (rubral or midbrain outflow tremor) refers to a hyperkinetic movement disorder characterized by mild resting and more severe postural and action tremor often with associated brainstem symptoms, dystonia and cerebellar deficits. This syndrome should prompt lesional evaluation with neuroimaging focused on the dorsal midbrain, cerebellar outflow tracts, and thalamus. Herein we report a 26-year-old previously healthy male who presented with 4 years of progressive horizontal diplopia, right Parinaud syndrome, and appendicular ataxia. Neuroimaging revealed a right dorsal midbrain enhancing lesion which completely resolved with intravenous methylprednisolone prompting a diagnosis of neuroinflammatory syndrome. Subsequent clinical and radiographic evaluations, however, revealed steadily progressive left dorsal midbrain syndrome with an expansile enhancing lesion which culminated 4 years from symptom onset with a right upper extremity low-frequency rest, postural and action tremor, ataxic dysarthria, and mild right dystonia with dysdiadochokinesia. Uncomplicated brainstem biopsy confirmed intracranial germinoma and the patient underwent definitive radiation therapy with dramatic radiographic response and partial clinical improvement. This case, which to our knowledge is only the second report of intracranial germinoma presenting as Holmes' tremor, highlights the critical importance of definitive tissue diagnosis in the evaluation of lesional brainstem pathology presenting as Holmes' tremor. Steroid responsiveness can be seen in non-inflammatory pathology including intracranial germinoma. Prompt evaluation and appropriate treatment are important as Holmes' tremor responds poorly to symptomatic therapies and response to radiation therapy is favorable for germinomas.
