The persistent craniopharyngeal canal is a rare, well-corticated midline congenital bony defect through the sphenoid bone between the sellar floor and the nasopharyngeal roof. The prevalence of persistent craniopharyngeal canal is reported to be 0.42%. A 42-year-old male was evaluated for nasal discharge and progressive vision loss; and underwent computed tomography and magnetic resonance imaging, which revealed a large craniopharyngeal canal with ectopic pituitary, lipoma, encephalocele, deformed globe with sclerochoroidal calcification and vertebrobasilar dolichoectasia. The presence of orbital and optic tract malformation, craniofacial anomalies, and tumors can be associated with the craniopharyngeal canal.

Background And Purpose: Morning glory disc anomaly (MGDA) is a congenital malformation characterized by a funnel-shaped optic disc excavation with radiating vessels and a central glial tuft. Imaging is essential to evaluate associated cephalocele and steno-occlusive vasculopathy. The goal of this study was to assess optic nerve, chiasmatic, and sphenoid bone morphology in MGDA.

Unlabelled: Intrasphenoidal encephalocoeles are acquired or congenital herniations of meninges and brain parenchyma through a structural sphenoid bone defect. Acquired causes are most common, either iatrogenic, post-traumatic, or spontaneous. However, defects in the lateral wall of the sphenoid sinus are uncommon and cephalocoeles through them relatively underexplored in current literature, warranting dedicated attention to unravel their complexities.

A 76-year-old female patient with a history of rheumatoid arthritis, Sjögren syndrome, and hypertension presented with headache, fever, and dysphagia. The patient was taking prednisone and leflunomide to treat rheumatoid arthritis. The headache was primarily left sided and occasionally radiated to the occipital region.

Congenital anomalies and defects of the skull base and calvarium encompass a broad and complex spectrum of pathologies. The clinical presentation is highly variable, and these anomalies may be discovered incidentally in asymptomatic individuals. Radiological assessment plays a pivotal role in precisely characterizing these abnormalities, facilitating the diagnostic process, and assisting in any preoperative preparation.
