Visual hallucinations may present secondary to neurologic, psychologic, or physiologic disturbances. Certain features and characteristics of visual hallucination are often attributed to various brain regions; however, with a broad list of causes and multifaceted pathophysiology, it is often hard to accurately localize. Overlapping clinical presentations may be due to the pathology of brain interconnections, rather than isolated brain regions themselves. In this study, we discuss a case of isolated, complex visual hallucinations secondary to occipital seizures in the radiologic absence of an ischemic injury. We propose that a network-based localizing lesion is responsible for this unconventional presentation.
视幻觉可能继发于神经、心理或生理紊乱。视幻觉的某些特征和特点通常归因于不同的脑区；然而，由于病因众多且病理生理过程复杂，往往难以准确进行定位。重叠的临床表现可能是由于脑内连接的病变，而非孤立的脑区本身所致。在本研究中，我们讨论了一例在影像学上无缺血性损伤的情况下，由枕叶癫痫继发的孤立性复杂视幻觉病例。我们认为基于网络的定位性病变是导致这种非传统表现的原因。
