Spontaneous splenic rupture is a well known, yet very rare complication of infectious mononucleosis with an estimated incidence of 0.06% to 0.5%. It primarily affects teenagers and young adults and is the leading cause of death in infectious mononucleosis. There is a 9% mortality rate associated with spontaneous splenic ruptures; in all lethal cases a rupture occurs within the first 10 days of symptoms onset from infectious mononucleosis. The present case report concerns a young female, who presented with abdominal pain, vomiting and positive Kehr’s sign two days after the onset of infectious mononucleosis symptoms. The patient was diagnosed with a spontaneous splenic rupture due to infectious mononucleosis and was treated operatively by laparotomy and splenectomy. The patient was successfully treated, and had no post operative complications.

Eosinophilic granuloma is one of the three clinical variants of Histiocytosis-X (eosinophilic granuloma, Hand-Schüller-Christian and Letterer-Siwe disease). Involvement of the temporal bone is relatively rare and initially silent. However, it can erode the mastoid cortex, destroy the tegmen and extend into the cranial vault, as well as erode the semicircular canals or cochlea. It usually presents as an aural polyp or postauricular swelling. Chronic ottorhea is what brings the patient to the ORL-Clinic. It is frequently confused with infectious diseases or neoplastic conditions of the temporal bone. In this paper we report 6 cases of eosinophilic granuloma in the temporal bone, discuss the plain radiological and CT findings and review the literature.
