Intrathoracic lipomas

Congenital infiltrative lipomas and retroperitoneal perirenal lipomas in a calf.

BACKGROUND Congenital lipocytic tumours have rarely been reported in cattle. Lipomas are benign tumours, but infiltrative lipomas have significant health implications due to their aggressive infiltrative growth pattern. CASE PRESENTATION A calf was born with skeletal malformations and soft tissue proliferations, primarily on the external thoracic wall. The calf was euthanized for welfare reas...

Two ileocecal valve lipomas

A 68-year-old woman presented with a 4-year unexplained intermittent abdominal pain recently complicated with rapidly transient obstruction episodes. Physical examination, plain radiograph and ultrasound of the abdomen were normal. At colonoscopy, a submucosal tumor (Fig. 1A) 0.5 cm in diameter prolapsing through the ileocecal valve was found. On removal of the tumor, after endoloop placement, ...

Thoracic lipomas simulating metastasis

Lipomas are common benign soft tissues tumors in adults. Intrathoracic lipomas are uncommon and can develop from the bronchus, lung, mediastinum, diaphragm, and thoracic wall, intrathoracic lipomas arising from the thoracic wall being particularly rare. Thoracic or pleural lipomas originate from submesothelial layers of parietal pleura, can extend into the subpleural, pleural, or extrapleural s...

Lipomas of corpus callosum

Intracranial lipomas (iLp) are very rare congenital malformative lesions, being less than 0.1% of intracranial tumors [1]. They originate from abnormal differentiation of the mesenchimal tissue of meninx primitiva [2–4]. Intracranial lipomas mainly localize in the pericallosal zone, where they are mostly asymptomatic, being frequently associated to other defects of differentiation of the midlin...
