TL;DR: Department for evaluation of right hypoacousia showed homogeneous high T1 signal of the lesion with signal drop on fat-saturated sequence, thus confirming the fatty composition of the mass.
Abstract: department for evaluation of right hypoacousia. Unenhanced Computed Tomography (CT) of the temporal bones showed a 15 mm hypodense mass infiltrating the right cerebellopontine angle (CPA) and the internal auditory canal (IAC) (arrows, Figure 1A). This mass showed negative Hounsfield Unit (HU) values in keeping with fatty content. Vestibulo-cochlear malformations were also found, including a hypoplastic lateral semi-circular canal (arrows, Figure 1B) and a globular aspect of the cochlea with an underdeveloped third turn (not shown). Magnetic Resonance Imaging (MRI) performed for better evaluation showed homogeneous high T1 signal of the lesion with signal drop on fat-saturated sequence, thus confirming the fatty composition of the mass (curved arrows, Figure 2B).

TL;DR: This case suggests that hypoplasia of the vertebrobasilar arteries can be a predisposing factor for posterior circulation ischemia, especially when additional vascular risk factors coexist.
Abstract: Cerebral ischemia may be rarely associated with a hypoplastic vertebrobasilar system. Intracranial lipoma is also a very rare congenital malformation. We report the case of a 52-year-old woman with vertebrobasilar transient ischemic attack associated with basilar artery hypoplasia and coincidental intracranial lipoma. She presented with sudden-onset dizziness, anarthria, and quadriplegia lasting for about 30 min. The patient's initial blood pressure was measured at 200/120 mm Hg. The magnetic resonance and computed tomographic images showed the absence of an acute ischemic lesion in the brain but revealed a hypoplasia of the basilar artery and bilateral V4 vertebral arteries. A lipoma of 11 mm in long diameter was also found in the quadrigeminal cistern and at the superior vermis. The electroencephalography, transthoracic echocardiogram, 24-h Holter monitoring, and transcranial Doppler ultrasonography, including patent foramen ovale study, were all noted as negative. The patient was treated with oral aspirin 100 mg, atorvastatin 10 mg, and antihypertensive medication. She had no symptom recurrence after the treatment. Our case suggests that hypoplasia of the vertebrobasilar arteries can be a predisposing factor for posterior circulation ischemia, especially when additional vascular risk factors coexist.

TL;DR: This case shows evolving magnetic resonance imaging features over two decades raising suspicion for low-grade neoplasm which was ultimately found to represent cortical dysplasia in a patient with intractable epilepsy.
Abstract: Intracranial lipomas represent approximately 1% of intracranial lesions generally felt to represent the abnormal persistence of the meninx primitiva and are commonly accompanied by various developmental brain abnormalities. We report a case of midline intracranial lipoma and evolving frontal lobe fluid-attenuated inversion recovery (FLAIR) abnormality concerning for glial neoplasm in a patient with intractable epilepsy. Our case shows evolving magnetic resonance imaging (MRI) features over two decades raising suspicion for low-grade neoplasm which was ultimately found to represent cortical dysplasia.
