Foramen tympanicum with symptomatic temporomandibular joint herniation.

Foramen tympanicum (FT), or foramen of Huschke, describes an uncommon anatomicvariant of a persistent bony defect connecting the external acoustic meatus to the temporomandibular joint (TMJ). Although rare, it can be associated with significant complications, such as TMJ herniation, salivary gland fistula, infectious or tumoral spread between the external acoustic meatus and the TMJ, or result in inadvertent ear injury during TMJ arthroscopy. To the best of our knowledge, this is the first case report of a symptomatic FT with a full description of computed tomography and magnetic resonance imaging findings.

MRA captures vasospasm in fatal migrainous infarction.

A 57-year-old woman presented with an escalation of her headaches which ultimately progressed to multiple strokes and death. MRI/MRA demonstrated diffuse vasospasm and other causes of stroke were excluded on premortem investigation and postmortem examination. Reversible MRI abnormalities, vasospasm on angiogram and fatal migrainous infarction have been previously reported; however, no previous case with this combination of clinical, imaging, and postmortem findings has been documented.
