A severe myelopathy was observed in a 9-year-old neutered male cat with a clinical history of chronic pancreatitis associated with deficiency of serum cobalamin and folates concentrations, and progressive spinal ataxia. The spinal cord lesions mainly involved the dorsal columns of the caudal cervical and cervico-thoracic segments, and were characterized by diffuse vacuolated myelin sheaths and axonal degeneration, marked gliosis, fibrosis and presence of gitter cells. The pancreas showed severe atrophy of the exocrine tissue, periductular fibrosis and infiltration of inflammatory cells, consistent with chronic interstitial pancreatitis. This condition can be accountable for cobalamin deficiency, as the pancreas is the only source of intrinsic factor in cats. The spinal cord lesions in the cat of this report resembled the subacute combined degeneration of the spinal cord described in human beings with cobalamin deficiency and hence a similar pathogenetic mechanism is hypothesized.

Spontaneous uterine rupture in the first trimester of pregnancy is uncommon and difficult to diagnose. Although extremely rare, it is important to consider the occurrence of placenta percreta as differential diagnosis of acute hemorrhagic abdomen at the beginning of pregnancy. We describe below a case of uterine rupture in the first trimester of pregnancy related to placenta percreta.

Situs inversus totalis is a congenital syndrome characterized by a total left-right transposition of all abdominal and thoracic organs. It may be associated with chronic respiratory conditions such as sinusitis and bronchiectasis, composing the Kartagener syndrome. If not detected, this condition may compromise the early diagnosis of surgical emergencies such as cholecystitis and appendicitis. A rare case of appendicitis in a patient with Kartagener syndrome is here reported.

Myelolipomas are rare benign neoplasms that commonly develop in the adrenal glands. Less frequently, they can affect other organs such as the liver, stomach, liver, lung, and retroperitoneum. It affects more women, with an average age of around 61 years. Histologically, they are composed of mature adipose tissue and hematopoietic cells. With the evolution of immunohistochemistry, there are characteristics that can differentiate from malignant tumors such as liposarcomas. Its treatment remains based on surgical resection and long-term outpatient follow-up.
