[Intracerebral hemorrhages following drainage of chronic subdural hematomas].

Background: postoperative intracerebral hemorrhage after drainage of chronic subdural hematoma is a rarely reported complication; however, its incidence, according to different series may be underestimated.

Case Report: this report presents a 77 year old male patient who, after the drainage of bilateral chronic subdural hematomas, developed an extensive hemorrhage in the thalami, basal ganglia, midbrain and pons, with extension into the ventricles and obstructive hydrocephalus.

Conclusions: compression by extra-axial collection decreases cerebral blood flow on the affected hemisphere and alters its vascular self-adjustment.

Cervical bronchogenic cyst mimicking thyroglossal cyst: case report and literature review.

Background: Bronchogenic cysts are rare congenital malformations of ventral foregut development, often with an intrathoracic location. Presentation at the cervical region is very rare.

Clinical Case: We present the case of a 29-year-old female who demonstrated a 3-cm medial neck mass in relation to the hyoid cartilage.

[Brain stem compression preceded by trigeminal neuralgia in a patient with vertebro-basilar and bilateral carotid dolichoectasia].

We described a patient who had left trigeminal neuralgia by vertebro-basilar dolichoectasia, who underwent microvascular decompression separating the basilar artery of the trigeminal nerve by interposing a vascular graft piece. Symptoms resolved completely after surgery. Nine years later, he has a recurrence of facial pain associated with rapidly progressive brainstem compressive symptoms.
