The authors report a case of a jugular bulb dehiscence extending to the tympanic cavity. They alert that the finding of a blue mass in the middle ear should evok the possibility of a vascular variant or abnormalitie. High resolution CT is extremely helpful in the correct diagnosis by showing the subtle and characteristic bone changes.
Histiocytosis X is an uncommon disease. Temporal bone involvement is a frequent head and neck manifestation. Most patients are under fifteen years of age. The authors report a case of a bilateral extensive temporal involvement complicated with vertigo and peripheric facial palsy. CT plays a dominant role in the diagnosis because of the ability to identify bone destruction, soft tissue involvement and intra-cranial histiocytosis more accurately.
The authors present a series of seven cases of hydatid cysts of the pancreas. This localization is rare since it accounts for less than 1% of the various sites of hydatid disease. The clinical signs are variable according to degree of bilio-pancreatic involvement. The preoperative diagnosis was established in three patients by ultrasonography, computed tomography and positive serology. Protruding dome was used in five patients. Distal pancreatectomy without splenectomy and Whipple resection were performed in other patients. There was no mortality and the postoperative morbidity was dominated by external biliary or pancreatic fistulae and local sepsis.
