It accounts for less than 1% of all astrocytomas. About 98% of PXAs originate supratentorially with the temporal lobe being the most common location. Cases of infratentorial PXAs are rarely reported in the medical literature. The tumor presents with a wide variation of symptoms based on the neuroanatomy involved with the location and size of the tumor, with seizures being the most reported symptom. The diagnosis depends on histological and clinical features along with radiologic features. We searched the keywords \"Pleomorphic xanthastrocytoma, PXA, cerebellum, infratentorium, astrocytoma, gliomas\" in the PubMed database; from 1979 to the current date, 28 cases were found in the medical literature featuring PXA in the infratentorium. We present the 29th case in the literature and the first in Syria. Our patient had a lesion in the right cerebellum and presented with a history of intermittent headache for 5 months followed by progressive gait disturbances and blurry vision and was misdiagnosed at the time of presentation with a high-grade glioma which is a common confusion because of the histological and clinical similarities. The patient underwent a suboccipital craniotomy, and adjuvant therapy with a combination of radiotherapy and chemotherapy with temozolomide was initiated at first. Then, the patient presented with a relapse of symptoms and went through another surgery where frozen sections suggested the diagnosis of PXA; further histopathological and immunohistochemical studies confirmed the diagnosis.

Intraventricular chemotherapy with methotrexate, cytarabine, and dexamethasone was initiated. We present clinical, imaging and cerebrospinal fluid (CSF) findings, including cytokine levels before and after intraventricular treatment: rapid decrease of cell count, lactate and profibrotic cytokine levels in the CSF following intraventricular chemotherapy was paralleled by a mild reduction of dura thickness in MRI. The already severely impaired visual acuity and hearing loss did not progress further. Treatment was complicated by exacerbation of previously subtle psychiatric symptoms. Follow-up was terminated after 6 months as the patient suffered from a fatal ischemic stroke. Autopsy revealed neurosarcoidosis as the underlying cause of HP.

An 82-year-old man developed disturbance of consciousness, dysphagia, and ataxic gait over a period of about 3 months. He was admitted to another hospital for aspiration pneumonia and recovered but was transferred to our hospital due to prolonged disturbance of consciousness. The patient was able to follow simple commands but had a tendency to somnolence. In addition to meningeal stimulation signs, the patient had left-dominant upper and lower limb ataxia and right-dominant limb spasticity. Brain FLAIR/T2-weighted imaging showed high-intensity lesions from the brainstem to the middle cerebellar peduncle bilaterally, medulla oblongata and upper cervical spinal cord, and T1-weighted imaging revealed contrast-enhanced lesions in the left middle cerebellar peduncle and cervical spinal cord. Although spinal fluid examination revealed elevated proteins, other laboratory tests indicated no evidence of infection, vasculitis, collagen diseases or tumors, and anti-ganglioside, anti-AQP4 and anti-MOG antibodies were negative. After admission, the patient again developed aspiration pneumonia, which progressed to acute respiratory distress syndrome, and he died on the 15th day of hospitalization.
