[Spinal cord compression secondary to epidural extramedullary hematopoiesis in thalassemia: a clinical case and review of literature].

Introduction: Extramedullary hematopoiesis generally occurs in a variety of hematological disorders where the normal functioning of the blood forming organs is disturbed. It is a common manifestation in thalassemia where it occurs as a compensatory phenomenon in order to combat long standing anemia. Spinal cord compression as a consequence of extramedullary hematopoiesis in the intraspinal epidural space is an extremely rare complication, though this complication has been reported more commonly in thalassemia.

Intracerebral arachnoidal cyst containing choroid plexus. Case report.

A case of an intracerebral "primary" arachnoidal cyst of the left fronto-parietal region is reported. No communication with the ventricular system or with subarachnoidal space was found at the first surgical procedure. It contained genuine choroid plexus and clinically behaved as an expansive intracranial mass.

Regeneration of the spinal ventral roots. An experimental study in cats.

From a clinical standpoint recovery of spinal nerve roots is less likely than that of peripheral nerves, despite their identical structures. This may be due to several factors including the length of gap to be bridged, changes in the proximal stump or neuroma, and chromatolysis. In this paper we discuss the roles of some of these factors in relation to the neuronal depopulation in the spinal cord anterior horn area following section of the anterior root.
