BACKGROUND
This is a case of a man aged 40 years with a past medical history of smoking, hypertension, polycythemia vera, intellectual disability, and schizophrenia who presented with generalized headaches, progressive loss of balance, and visual disturbance for 1 month.
CASE DESCRIPTION
Head computed tomography and magnetic resonance imaging revealed a right cerebellar hematoma associated to heterogenous lesion with cystic components and flow-voids in the right cerebellar hemisphere. A ventriculoperitoneal shunt was placed with partial improvement of symptoms. Further vascular studies confirmed presence of a vascular nidus with significant arteriovenous shunting. The patient later required intervention for cerebellar arteriovenous malformation (AVM) removal. Microscopic evaluation of the lesion showed the AVM nidus, as well as large, vacuolated stromal cells and numerous thin-walled vessels. Immunostaining with inhibin and S-100 highlighted the stromal cells with numerous lipid-containing vacuoles. The earlier mentioned findings were consistent with the diagnosis of an AVM with coexistent hemangioblastoma of the right cerebellar hemisphere.
CONCLUSIONS
Coexistence of hemangioblastomas and AVMs are extremely rare, and only 3 cases have been reported previously in the literature.

Review
BACKGROUND
Hemangioblastomas (HBMs) are benign vascular neoplasms that most commonly arise within the cerebellum. Although other vascular lesions should be considered in the differential diagnosis, HBMs rarely resemble aneurysms on neuroimaging and only 1 case of a cerebellar HBM mimicking a posterior fossa aneurysm has been reported. Here we describe a retromedullary HBM that masqueraded as a distal posterior inferior cerebellar artery (PICA) medullary branch aneurysm.
CASE DESCRIPTION
A 63-year-old asymptomatic male was incidentally diagnosed with an unruptured 3-mm left PICA aneurysm via computed tomography angiography during a workup for carotid stenosis. Two years later, the presumed aneurysm enlarged to 6.5 mm and prompted elective treatment. Endovascular treatment was unsuccessful, and the patient was immediately transitioned to a craniotomy for aneurysm clipping. After microsurgical dissection, the lesion was visualized on the posterior medullary surface with several small arterial feeders extending from the brainstem into the aneurysm dome, but no major parent vessel was observed. Because a clip could not be safely applied to these small vessels, they were instead coagulated and the lesion was completely resected. Final pathology revealed hemangioblastoma (World Health Organization grade I).
CONCLUSIONS
To our knowledge, this is the second case of HBM mimicking a PICA aneurysm. Given the rarity of PICA medullary branch aneurysms and their highly symptomatic nature, other etiologies, especially HBM, should be strongly considered when an apparent distal PICA aneurysm is diagnosed in an asymptomatic patient. If the lesion is unamenable to endovascular treatment, there should be high suspicion for HBM and subsequent craniotomy should be pursued.

Cerebellar hemangioblastomas with pregnancy is rare, but coexistence of pregnancy and recurrent cerebellar hemangioblastomas is rather rare. And coexistence of other diseases during pregnancy usually leads to misdiagnosis because of pregnancy reaction. A 29-year-old woman, at the 8th week of pregnancy, complained of nausea, vomiting, and episodic posterior occipital pain and was misdiagnosed pregnancy reaction without any special treatment during her several visits to local hospital. The patient was diagnosed cerebellar hemangioblastomas 14 years ago, after surgery, she received regular re-examination without recurrence. At the 15th week of pregnancy, the situation of the patient got worse, and she was admitted to our hospital. Brain magnetic resonance imaging showed a lesion in cerebellum. It was considered to be cerebellar hemangioblastomas and was confirmed finally by postoperative pathological examination. In clinical practice, differential diagnosis is of great importance during pregnancy because many other diseases can mimic pregnancy reaction. In this patient, the intracranial hypertension caused by recurrent cerebellar hemangioblastomas was misdiagnosed as pregnancy reaction and it was suggested that the change of hormones, neuroendocrine, and cardiovascular function promoted the recurrence of cerebellar hemangioblastomas.

Retinal hemangioblastomas are one of the most common and early manifestations of Von Hippel-Lindau disease. Early detection is the key in their management. When left untreated, these benign neoplasms may continue to grow and result in scleral infiltration and extraocular extension warranting enucleation of the globe.

Sporadic cerebellar hemangioblastomas are rare with majority of these tumors presenting as a part of von Hippel-Lindau syndrome. We demonstrate an unusual case of a symptomatic sporadic cerebellar hemangioblastoma mimicking a meningioma on MRI and 68 Ga-DOTANOC PET imaging.
