Extra-axial fluid collections following decompressive craniectomy have been observed in a variety of patient populations. These collections have traditionally been thought to represent extra-axial signs of hydrocephalus, but they often occur even in settings where hydrocephalus has been optimally treated. This study aims to elucidate the phenomenon of extra-axial fluid collections after decompressive craniectomy in patients with treated hydrocephalus, in order to improve identification, classification, prevention and treatment. ⋯ In these patients, the term "external hydrocephalus" does not appropriately capture the relevant pathophysiology. Instead, we define a new phenomenon, "Craniectomy-associated Progressive Extra-Axial Collections with Treated Hydrocephalus" (CAPECTH), as progressive collections despite aggressive cerebral spinal fluid (CSF) drainage. Our data indicate that early cranioplasty can help prevent the formation and worsening of this condition, presumably by returning normal CSF dynamics.

Case Reports
Life-threatening neurovascular injuries associated with recreational use of "banana" boats.
Banana boat rides are a popular form of recreation worldwide. Recommendations that speed should not exceed 15 mph, passengers should wear protective gear, and an observer should be present on the towing boat are generally ignored. Medical personnel at tourist venues and general practitioners may not be attuned to the risk of serious injury. ⋯ In the first patient, medical management failed and endovascular treatment was required due to neurological deterioration. In patient two, anticoagulation therapy prevented embolic sequelae. Boat operators, passengers, and the medical personnel who are first to see these patients should be aware of the risk of arterial dissection to facilitate early detection of these potentially life-threatening injuries.

Pramipexole is a non-ergot dopamine agonist that is used frequently as a single therapy or in combination for the management of Parkinson's disease. Common side effects are daytime drowsiness, hypotension, hallucinations and compulsive behaviour. We describe a patient who developed severe chronic and extensive lymphoedema after pramipexole was introduced and that resolved after its cessation.
