INTRODUCTION: Spinal teratomas are extremely rare tumours, and their association with split cord malformation is even rarer. CASE REPORT: This is a case report of an infant with a large teratoma with a lipomyelomeningocele along with a split cord malformation and with an unusual accessory penis and scrotum on the back over the swelling. This, to our knowledge, is the first such case reported in the English literature.
We report the first case of brain abscess due to Enterococcus avium in a 19-year-old man with chronic otitis media since childhood. The patient presented to the emergency department in a comatose condition. Contrast-enhanced brain computed tomography scan showed a hypodense area with ring enhancement in the right temporal lobe and mass effect with subfalcine and transtentorial herniation. Emergency temporal burr hole operation was performed and pus drained out, but the patient succumbed to his illness. Culture of the aspirated pus yielded growth of gram-positive cocci identified as E avium, an infrequent pathogen of human infections. The association of E avium with brain abscess further extends the clinical spectrum of this rare pathogen.
This is report on four cases of giant pituitary tumors that developed postoperative pituitary apoplexy after they had undergone a partial tumor resection. Three patients had undergone surgery by a transsphenoid route and one patient underwent surgery by transcranial route. Postoperative CT scan showed hemorrhagic expansion of residual tumor mass. All the four patients were re-explored transcranially and hemorrhagic swelling of the tumor was observed. In three cases, the tumor had swollen to a size greater than twice the original tumor. All the four patients had a fatal outcome.
Posterior fossa extradural hematoma (PFEDH) is an infrequent condition. Though numerous neuropathological sequelae of cardiopulmonary bypass have been described, to the best of the authors' knowledge, PFEDH after cardiac surgery has not been reported in the English literature. We report a 4-year-old boy with tricuspid atresia, who underwent cardiac surgery under cardiopulmonary bypass. On the 2nd postoperative day, his neurological condition deteriorated, and a CT scan of the head revealed a large PFEDH with mass effect and hydrocephalus. He underwent a midline suboccipital craniectomy and evacuation of PFEDH. There was diffuse bleeding from the dura; however, no specific site of bleeding was identified. The child started following commands on the 1st postoperative day, had an uneventful recovery and was discharged on the 10th postoperative day. On follow-up, 1 year after the surgery, he was doing well.
