A rare expression of neural crest disorders: an intrasphenoidal development of the anterior pituitary gland.

Congenital abnormalities of the pituitary gland are rare and may be associated with midline cranial, orbital, and facial anomalies and with hormonal insufficiency. Here we report a case of asymptomatic, abnormal migration of the adenohypophysis. The normally developed adenohypophysis was located in the sphenoid bone and developed on the intersphenoidal septum, extending from the superior pharyngeal wall to the floor of the sella turcica (craniopharyngeal canal).

SAPHO syndrome of the temporomandibular joint associated with sudden deafness.

We report a case of arthritis of the temporomandibular joint (TMJ) associated with sclerosing osteomyelitis of the mandible and temporal bone, causing deafness. The presence of a palmoplantar pustulosis established the diagnosis of SAPHO syndrome. SAPHO (an acronym referring to synovitis, acne, palmoplantar pustulosis, hyperostosis, and osteitis) syndrome is defined by the association of characteristic osteoarticular and dermatologic manifestations, with diffuse sclerosing osteomyelitis of the mandible being a part of this entity.

Atlantoaxial fusion and retrodental pannus in rheumatoid arthritis.

Study Design: This study analyzed the influence of atlantoaxial fusion in rheumatoid arthritis patients on inflammatory retrodental pannus.

Objectives: To determine the value of fusion on the magnitude of pannus as a compressive structure on the spinal cord.

Summary Of Background Data: Transverse and vertical instability may lead to neurologic deficits from spinal cord compression.

Foraminal changes with distraction and compression of the L4/5 and L5/S1 segments.

The width of the foramen in the lumbar spine is directly related to the position of the vertebrae. In an MRI study the measurements of the cross-sectional area of the neuroforamen of L4/5 and L5/S1 in neutral position, segmental distraction and compression were calculated. Nine cadaver specimens were investigated and the foraminal width of L4/5 and L5/S1 was measured.

[Radiological assessment of degenerative lumbar stenosis].

The evaluation of central and lateral lumbar spinal stenosis is equally well performed by CT, CT-myelography and MRI. Stenosis can be quantified and localized in order to optimize orthopedic treatment. Each of these modalities has inherent strengths and weaknesses.
