Posterior fossa subdural hematoma formation in the newborn is an infrequently reported event. It is characterized by a complicated delivery, usually at term, followed by developing lethargy and irritability within the first few days of life. Respiratory irregularities, tense anterior fontanelle, and increasing head circumference ensue, accompanied by a falling hemoglobin and blood-stained cerebrospinal fluid. Various cranial nerves may also be involved. Previously reported cases have been marked by diagnostic delays that affected the subsequent outcome of some of the patients. Computed tomography (CT) allows for earlier confirmation of the diagnosis, especially where coronal views are employed. Three cases are reported here to illustrate the above features.

Posterior fossa tumors are commonly associated with obstructive hydrocephalus. Relieving the raised intracranial pressure by draining the cerebrospinal fluid presents the possibility of reverse herniation of the brain. A 5-year-old male child with a diagnosis of posterior fossa space-occupying lesion and hydrocephalus was scheduled for craniectomy in the prone position. After craniectomy, the surgeons placed an intraventricular shunt catheter to drain out cerebrospinal fluid in an attempt to reduce the tense brain so as to facilitate easy dissection of the tumor. The patient had sudden and severe bradycardia followed by asystole. A diagnosis of reverse coning was made. Immediately, the surgeon injected 10-15 mL normal saline into the ventricles. There was a spontaneous return of the sinus rhythm and the rest of the course of surgery was uneventful. We present this case showing a rare phenomenon and its successful management.

Acute traumatic compartment syndrome of the foot is a serious potential complication after fractures, crush injuries, or reperfusion injury after vascular repair. Foot compartment syndrome in association with injuries to the ankle is rare. This article presents a case of acute compartment syndrome of the foot following open reduction and internal fixation of an ankle fracture. A 16-year-old girl presented after sustaining a left ankle injury. Radiographs demonstrated a length-stable posterior and lateral malleolar ankle fracture. Initial treatment consisted of a bulky splint and crutches pending the improvement of her swelling. Over the course of a week, the soft tissue environment of the distal lower extremity improved, and the patient underwent open reduction and internal fixation of both her fibula and distal tibia through 2 approaches. Approximately 2 hours from the completion of surgery, the patient reported worsening pain over the medial aspect of her foot and into her calcaneus. Physical examination of the foot demonstrated a swollen and tense abductor hallicus and heel pad. Posterior tibial and dorsalis pedis pulses were palpable and her sensation was intact throughout her foot. Emergently, fasciotomy of both compartments was performed through a medial incision. Postoperatively, the patient reported immediate pain relief. At 18-month follow-up, she reported no pain and had returned to all of her preinjury athletic activities.
