Heterotopic brain tissue in the lung causing acute respiratory distress in an infant.

Abstract

X. 4 sion showed a large tension cyst in the right chest, displacement of the heart to the left, and anterior herniation of the mediastinum. The infant was taken to the operating " theatre and a needle was inserted into the right chest cavity with the release of some air, but little clinical improvement occurred. A thoracotomy was hurriedly performed. A large thin walled cyst in the upper lobe and two large cysts in the lower lobe of the right lung were resected. The child made an uneventful recovery and subsequently had surgery to correct X ' ',

Heterotopic Brain in the Pterygopalatine Fossa

“…Systemic embolization of brain tissue following intrauterine trauma or aspiration of brain tissue fragments from the amniotic fluid are two hypotheses proposed to explain these lesions (9,10).…”

“…Heterotopic brain or neuronal tissue comprising an encephalocele may be hyperintense on T2-weighted images because of dysplastic neural tissue (5,18). Heterotopic brain containing functioning choroid plexus elements may present as a cystic mass owing to production of cerebrospinal fluid (10,14,15). It may enhance depending on the vascularity or presence of choroid plexus.…”

“…Over 140 cases of nasalheterotopic brain have been described in the literature (7,73,74). Less common sites for heterotopic brain include the scalp (1), orbit (2), lip (3), tongue (4), soft and hard palates (5, 6), nasopharynx and oropharynx (7-g), and lung (10).…”

“…Other reported sites of heterotopic brain include the scalp (1), orbit (2), lip (3), tongue (4), patate (5,6), pharynx (7)(8)(9), and lung (10). Heterotopic brain involving the nose, face, or scalp is frequently detected early in life at physical examination; however, heterotopic brain located deep within the head and neck is often asymptomatic and, hence, when detected, is usually an incidental finding on radiologic examinations performed for unrelated reasons.…”

Where All Can Ectopic Brain Be Found

“…Ectopic brain tissue has also been reported from a mass simulating a tonsil [9], from the lip [10], within neck masses [11], in a choristoma on the back [12], within the eighth cranial nerve [13] and in the pterygo-palatine fossa [14]. It has also been known to be ectopically located in the subpleural space [15] or within the lungs and thereby presenting as respiratory distress [16].…”
