Caudal regression syndrome is a rare congenital anomaly with characteristic agenesis or dysgenesis of caudal vertebrae varying from isolated partial agenesis of coccyx or entire lumbosacral vertebrae.1,2 It may be associated with congenital anomaly of spinal cord, genitourinary tract, and gastrointestinal tract.3–5 The children with extensive bony defects in caudal regression syndrome may prese...

We present two cases of idiopathic spinal epidural lipomatosis. Case 1: A 77-year-old man experienced tightness in bilateral lower extremities and neurogenic claudication for 1 year. He was overweight with a body mass index of 30.8 kg/m2. Magnetic resonance imaging revealed extensive epidural lipomatosis of lumobsacral spine with significant constrictive compression of the thecal sac. Case 2: A...

A new photosynthetic, sand-dwelling marine dinoflagellate, Ailadinium reticulatum gen. et sp. nov., is described from the Jordanian coast in the Gulf of Aqaba, northern Red Sea, based on detailed morphological and molecular data. A. reticulatum is a large (53-61 μm long and 38-48 μm wide), dorsoventrally compressed species, with the epitheca smaller than the hypotheca. The theca of this new spe...

We have shown recently that the bovine corpus luteum (CL) possesses specific luteal cell surface membrane binding sites for progesterone. We have now confirmed and extended these observations to compare the subcellular distribution of these binding sites in developing, mature and regressing CL. The median buoyant densities of luteal progesterone binding sites from early-, mid- and late-luteal p...

Dementia and hydrocephalus in an elderly female were related to basilar impression caused by Paget's disease of the skull. Ventricular and lumbar thecal pressures were normal, but isotope cisternography suggested obstructive hydrocephalus. The patient improved after ventricular shunting. The importance of prompt investigation of dementia occurring in patients with Paget's disease is emphasised.

Pneumocephalus and pneumorrhachis are related to transgression of the barriers to the central nervous system. We present a patient with a Pancoast tumor treated with palliative chemoradiation who developed symptomatic spinal and intracranial air caused by spontaneous bronchopleurodurosubarachnoid fistula secondary to direct tumor invasion into the thecal sac.
