CT findings in neonatal hypothermia.

BACKGROUND: Newborn infants are particularly prone to hypothermia, a condition with a high mortality. OBJECTIVE: To study the CT brain patterns in infants with hypothermia and neurological symptoms. MATERIALS AND METHODS: We reviewed the brain CT of nine infants with neonatal hypothermia, multiple organ failure, seizures and coma. RESULTS: Two infants had normal CT scans, acutely and at follow-up, and were clinically normal at follow-up. In seven infants, CT showed diffuse cerebral oedema, with reversal of the normal density relationship between grey and white matter and a relative increased density of the thalami, brainstem and cerebellum - the 'reversal sign'. In six surviving infants with severe developmental delay, follow-up CT revealed cerebral atrophy with multicystic encephalomalacia. CONCLUSIONS: The 'reversal sign' has been described in the abused child, birth asphyxia and anoxia due to drowning. Neonatal hypothermia is offered as a further cause.

Ganglioneuroma: an 'incidentaloma' of childhood.

In adults clinically silent adrenal masses can be discovered incidentally in imaging studies. Most of these 'incidentalomas' are benign, non-functioning adenomas. In contradistinction, in infancy and childhood the most common adrenal mass is the neuroblastoma, a malignant neural crest tumour. Four children are described, each with a benign neural crest tumour - ganglioneuroma - incidentally discovered by conventional radiography or sonographic examination. Complete surgical excision resulted in total recovery of all the children.

[Chronic tophaceous gout].

A 51-year-old immigrant from the Caucasus had had chronic tophaceous gout for over 20 years, but had never been treated with anti-hyperuricemic drugs. He had developed large, multiple tophi in many locations, including both ankles and feet. The enormous size and unique location of the tophi caused considerable pain, and difficulty in standing and on walking. Since surgical removal of the tophi was refused by the patient, a course of allopurinol, 300 mg/day, was begun.

Vertebral pneumatocyst. A case report.

STUDY DESIGN: This study illustrates intraosseous pneumatocyst of the vertebral body, a benign lesion. OBJECTIVES: To review the incidence and location of this benign lesion during a 1-year period. SUMMARY OF BACKGROUND DATA: Intraosseous pneumatocyst is a rare benign condition, commonly seen in iliac bone or sacrum. The etiology of this entity is unclear. Other locations of these lesions are very rare, and only a few isolated cases are reported in the literature. METHODS: In the last year (1994-1995), vertebral pneumatocyst was incidentally found in four patients who underwent computed tomography examination for presumptive discal lesion. Axial computed tomography with 2- and 4-mm slice thickness was performed. RESULTS: The typical computed tomography patterns of intraosseous pneumatocyst involving the cervical, dorsal, or lumbar spine were found. The bony structure and joints were normal. To the best of our knowledge, intraosseous pneumatocyst located in the spinal process has not been reported. CONCLUSIONS: Intraosseous pneumatocyst is a benign lesion. Biopsy and follow-up are unnecessary.

Pelvic granulocytic sarcoma.

Granulocytic sarcoma is an uncommon extraskeletal tumor most frequently associated with leukemia. We present a case of bone location with unusual pattern in a patient with no evidence of myeloproliferative disorder at presentation or follow-up.

[Complete traumatic dislocation of the cervical spine without permanent neurologic sequelae].

The authors present their experience with an unusual case of fracture of the lower cervical spine with complete dislocation at C6-C7 level, in a young man involved in a car accident. An initial unilateral root deficit progressed shortly after admission to hospital, to a classical Brown-Sequard' syndrome. The development of a partial cord lesion in spite of the severe dislocation of the spine, could be attributed to the simultaneous "traumatic laminotomy" and the enlargement of the neural canal at the level of the vertebral sliding, that occurred as a result of bilateral fracture of the posterior arc of the 6th cervical vertebra and its separation from the anteriorly displaced vertebral body. Our management consisted in cortico-therapy and early skeletal traction with prolonged immobilization of the cervical column. The closed, rapid reduction of the dislocation under neurologic and radiologic monitoring was followed by successful alignment of the neural canal at 48 hours after injury, with progressive neurologic recovery and by "auto-fusion" of the fractured bones with subsequent, stable and long-lasting consolidation.
