Background: Intracranial teratomas represent a rare subset of neoplasms characterized by tissues derived from multiple germ layers within the cranial cavity. These tumors, originating from primordial germ cells, exhibit diverse clinical presentations and histopathological features. While predominantly located along the midline axis, including the suprasellar cistern and pineal region, they can also manifest in less common areas such as ventricles and hypothalamic regions.

Background: The Klippel-Feil syndrome (KFS) is a rare congenital anomaly characterized by the fusion of cervical vertebrae, which may be associated with other malformations, such as dermoid tumors and teratoma. Some theories explain the embryology of these associations. Another condition that may be present is the dermal sinus (DS), communication between intracranial tumors and the subcutaneous tissue, and predisposing infections.

Article Synopsis
  • Spinal epidural abscess is a rare and severe condition that can lead to serious complications like spinal cord compression and neurological issues.
  • A case study details a 31-year-old patient whose infectious cellulitis in the hand progressed to a spinal epidural abscess, diagnosed through clinical evaluation and MRI.
  • Treatment involved a surgical procedure called laminectomy, resulting in a full recovery; the article also highlights the importance of early diagnosis to prevent complications.

Non traumatic subdural hematomas are rare, especially those associated with intracranial meningiomas. Among the most common meningiomas associated with spontaneous bleeding are angioblastic and malignant meningioma variants. The pathophysiological mechanisms of this association are not yet fully understood.
