Bronchogenic cyst presenting as mediastinal mass with pleural effusion

ABSTRACT: Mediastinal bronchogenic cysts are usually identified on computed tomography (CT)

as welldefined masses of !ariable density that may contain rim calcifications" #leural effusion has

ne!er been described in association with these cysts"

$e report two cases of bronchogenic cysts with unusual presentation because of an association with

a pleural effusion not e%plained by pulmonary infection" The patients were studied with CT scan(n&') and magnetic resonance imaging (MR) of the chest (n&)"

n this case* the pleural effusion directed diagnosis towards lung tumour+ and the diagnosis of

bronchogenic cyst was made on thoracotomy" Surgical e%cision of the cyst was difficult because of

pericystic adhesions to ad,acent organs" Therefore* solely on the finding of a pleural effusion*

pericystic inflammation had to be suspected"

Bronchogenic cysts are congenital abnormalities resulting from embryological budding of the bronchial

tree; they often arise near the carina [13]. Mediastinal bronchogenic cysts are frequently detected

incidentally, on routine chest radiographs. hey manifest as smooth and !ell"circumscribed masses near

the carina [#, 3].

$e describe t!o cases of bronchogenic cyst that appeared as mediastinal mass !ith pleural effusion,

!ithout pulmonary infection. o our %no!ledge, this radiological manifestation, in association !ithbronchogenic cyst, has not pre&iously been reported.

computada como masas bien definidas de densidad !ariable 3ue pueden contener calcificaciones" 0l

derrame pleural nunca ha sido descrito en asociaci4n con los 3uistes" Se reporta un caso de 3uiste

broncog.nico con una presentaci4n inusual por su asociaci4n con derrame pleural no e%plicado por

infecci4n pulmnar" 5os pacientes fueron estudiados con TC y RM de t4ra%"

0n ese caso el derrame pleural fue atribuido al diagn4stico de tumor pulmonar* y el diagn4stico de

3uite broncog.nico fue hecho en la toracotom/a" 5a escisi4n 3uir6rgica del 3uiste fue dif/cil por

adhesiones peri3u/sticas a los 4rganos adyacentes" #or lo tanto* solamente por el derrame pleural*la inflamaci4n peri3u/stica deb/a ser sospechada"

'os quistes broncog(nicos son anormalidades cong(nitas resultantes de ciernes embriol)gicos del *rbol

bronquial, son usuales cerca de la carina. 'os quistes broncog(nicos mediastinales son detectados

frecuentemente de forma incidental, en radiograf+as de t)ra de rutina. -e manifiestan como masas lisas

bien circunscritas.l caso descrito es de quiste broncog(nico mediastinal con derrame pleural sin infecci)n pulmonar. -eg/n

ABSTRACT

'ung cancer is the leading cause of cancer"related death in urope and the 2-. solated metastases to

s%eletal muscle and the mandible are &ery uncommon.

'ung cancer is the leading cause of cancer"related death !orld!ide and the second most common cancer

in both men and !omen. 4espite impro&ements in imaging technologies o&er the past t!o decades, the

ma5ority of lung cancers are disco&ered because of the de&elopment of distant metastases. 6ematogenous

spread !ith multiple organ in&ol&ement is frequently reported. 7ommonly, metastases from lung cancer

in&ol&e the li&er, adrenal glands, bone and brain [1]. Muscle metastases are uncommon [#]. Mandible

metastasis from lung cancer is a rare condition that may occur in the late stages of the disease [ 3]. $e

describe t!o cases of non-small"cell lung cancer 89-7'7: metastasis to thigh muscle and mandible bone

8as first clinical e&idence:, and discuss treatments and outcomes.

Acute #ulmonary 0mbolism

ABSTRACT

Culmonary embolism and deep &enous thrombosis represent the spectrum of one disease. hrombi

commonly form in deep &eins in the calf and then propagate into the proimal &eins, including and abo&e

the popliteal &eins, from !hich they are more li%ely to embolie.

Culmonary embolism, most commonly originating from deep &enous thrombosis of the legs, ranges from

asymptomatic, incidentally disco&ered emboli to massi&e embolism causing immediate death. 7hronic

sequelae of &enous thromboembolism 8deep &enous thrombosis and pulmonary embolism: include the

post"thrombotic syndrome1and chronic thromboembolic pulmonary hypertension.#0cute pulmonary

embolism may occur rapidly and unpredictably and may be difficult to diagnose. reatment can reduce

the ris% of death, and appropriate primary prophylais is usually effecti&e. Catients treated for acute

pulmonary embolism appear to be almost four times as li%ely to die of recurrent thromboembolism in the

net year as patients treated for deep &enous thrombosis 8rate of death, 1.DE &s. .=E:. 3he primary

focus of this re&ie! is acute pulmonary embolism of thrombotic origin.

Tromboembolismo pulmonar agudo"

R0S1M02

l embolismo pulmonar y la trombosis &enosa representan el espectro de una misma enfermedad. 'os

trombos son formados com/nmente en &enas profundas en la pantorrilla y luego se propagan a &enas m*s

proimales, incluyendo las &enas popl+teas, que son las m*s propensas a emboliar.

l embolismo pulmonar, m*s com/nmente originado en trombosis de las &enas profundas de las piernas,

puede encontrarse asintom*tico, incidentalmente encontrado y embolismo masi&o que causa una muerte

inmediata. -ecuelas cr)nicas de tromboembolismo &enoso 8trombosis &enosa profunda y embolismo

pulmonar: incluyen s+ndrome post tromb)tico e hipertensi)n pulmonar tromboemb)lica cr)nica. lembolismo pulmonar agudo puede ocurrir r*pidamente o de manera impredecible y puede ser dif+cil de

diagnosticar. l tratamiento puede reducir el riesgo de muerte, y la profilais primaria apropiada

usualmente es efecti&a. 'os pacientes tratados por embolismo pulmonar agudo parecen ser cuatro &eces

m*s propensos a morir por embolismo recurrente en el siguiente ao tanto como los pacientes tratados por

trombosis &enosa profunda. n enfoque primario de esta re&isi)n es embolismo pulmonar agudo de

origen tromb)tico.
