Black turbinate sign - an important MRI sign of mucormycosis; a deadly form of acute invasive fungal sinusitis seen in diabetic and immunocompromised patients. Angioinvasive fungal hyphae cause infarction as they invade the nasal mucosa. This results in a ‘black’ area of non-enhancing mucosa which stands out against the normal enhancing mucosa. The sign may be critical to early detection and treatment of mucormycosis which when untreated can result in blindness and death within 2 weeks.

Fahr's disease: CT-scan shows bilateral basal ganglia calcifications with bilateral subcortical white matter calcifications, compatible with Fahr's disease (familial cerebral ferrocalcinosis).

Fahr's disease is usually initially asymptomatic in most patients. The differential diagnosis of basal ganglia calc.

Choroid plexus papilloma are amazing tumours, unfortunately found mostly in children. One of the interesting tidbits is that unlike most other brain tumours, which are more common in the posterior fossa in children and supratentorial compartment in adults, this relationship is reversed; most paediatric CPP are found in the trigone of the lateral ventricle!

The features are typical of an oribtal cavernous haemangioma. Akin to haemangiomas elsewhere, the enhancement would fill in progressively and appear homogeneous if delayed post contrast images were obtained.
