Out of 2,888 blunt head injuries that were treated at the Hermann Hospital Trauma Center of the University of Texas at Houston, only 123 temporal bone fractures were diagnosed in 110 patients. The clinical diagnosis was confirmed with high resolution computerized tomography of the temporal bones. Three main categories of fractures were identified: oblique in 74%, longitudinal in 13% and transverse in 13%. ⋯ Thirteen patients who had delayed facial paralysis also recovered spontaneously. One third of the patients had persistent unsteadiness 6 weeks following the injury. Other unusual complications encountered include 6 cases of abducent paralysis, 2 cases of trigeminal paralysis and 2 cases of aseptic sigmoid sinus thrombosis.

Two cases of isolated traumatic rupture of gallbladder are reported, including results of ultrasound and CT scan imaging, and the relevant literature reviewed. Preoperative diagnosis is suggested by presence of a perivesicular collection. Fine needle puncture aspiration of the collection provides confirmation of diagnosis if a bilious or biliohemorrhagic fluid is withdrawn.

Case Reports
[Suprascapular and axillary subcutaneous emphysema after perforation of a pharyngolaryngeal cancer].
A case is reported of a laryngeal cancer recurrence that had invaded and then eroded the pharynx. The fistula produced was the cause of a thrombophlebitis of upper limb, and subcutaneous emphysema limited to the right shoulder region due to radiosclerosis of soft tissues of neck.

Three patients had colonic perforation as a result of percutaneous nephrostomy and lithotripsy. These patients did not respond to conservative measures and required surgery (colostomy, hemicolectomy, drainage). ⋯ Fluoroscopy and ultrasonography do not allow simple and accurate information of the position of the colon, and CT is the method of choice. Some factors seem of high risk : thin and young patient, female, dilated pelvo-calyceal system, associated colonic obstruction.

A case of left infrarenal vena cava is detected by ultrasonography and confirmed inferior cavography. Embryogenesis of the inferior vena cava aids understanding of this type of congenital anomalies. Ultrasonographic diagnosis is based on the absence of right infrarenal vena cava, the presence of a vascular structure left to the abdominal aorta an a normal hepatic segment of inferior vena cava.
