[Five case reports on granulosa cell tumors in cattle with practical information on diagnosis and possible progression].

Five cases of ovarian tumors (granulosa cell tumors) in cattle are presented from the patient load of the Vetsuisse University of Zurich and Bern. The aim of this work was to demonstrate the variable development of the illness and to indicate diagnostic and therapeutic possibilities to the practicing veterinarians. Case 1 shows bilateral appearance and the development of malignancy and metastases.

Internal herniation of the small and large intestines in 18 cattle.

Internal intestinal hernia was diagnosed during laparotomy in 18 cattle with a tentative diagnosis of ileus; the diagnosis was made during a second laparotomy in two cases. In 14 cattle, the hernial orifice was in the visceral layer of the greater omentum and the intestines had herniated into the caudal recess of the omental bursa. In two animals both the visceral and parietal layers had an opening; in one, the orifice was in the mesoduodenum, and in the other in the mesojejunum.
