Tuberculomas are small tumor-like lumps that can be seen, usually in large numbers, in central nervous system involvement of tuberculosis. Giant tuberculomas that are big enough to cause symptoms of compression are also encountered, though rarely. When they are really large, tuberculomas may result in increased intracranial compression, neurologic deficits, or epileptic attacks. Giant tuberculomas may be confused with brain tumors on cranial magnetic resonance imaging. Cranial magnetic resonance imaging and histopathology examinations are used for diagnosis. Although magnetic resonance imaging is useful for diagnosing tuberculoma, histopathology examination is the gold standard for a final diagnosis. This paper presents a case involving a 66-year-old patient who complained of headache, imbalance and dizziness, and underwent an operation in the neurosurgery clinic with a pre-diagnosis of brain tumor, and was then diagnosed with intracranial giant tuberculoma.

Giant intracranial aneurysms, especially giant aneurysms of the distal posterior inferior cerebellar artery (PICA), remain the most difficult and challenging cerebrovascular lesions for neurosurgeons to treat. The morbidity and mortality rates of microsurgical clipping are relatively high, and endovascular embolization is also associated with many complications. In the present report, the case of a 46-year-old female patient who presented with headache and dizziness for 3 years, which was aggravated and combined with limb weakness for 1 day, is presented. A CT scan showed a lesion occupying the fourth ventricle, with slight bleeding. A MR scan also revealed a lesion occupying the fourth ventricle and compressing the brainstem, and there was distortion of the cisterns around the brainstem. CT angiography examination showed a giant irregular aneurysm located in the PICA. After evaluation, the PICA aneurysm was removed, and the PICA was clipped via a microsurgical technique without ischemia or neurological sequelae. Long-term follow-up demonstrated that the symptoms of headache and dizziness disappeared without relapse. Based on a review of the literature, this method may represent an alternative strategy for the treatment of giant PICA aneurysms, especially for aneurysms not suitable for direct clipping or endovascular embolization.
