Wedge Post Obstructive

55-year-old male presenting with dyspnea
Axial CT at the level of the carina shows atelectasis of the RUL caused by a central obstructing lesion in the right upper lobe bronchus resulting in atelectasis of the RUL characterized by a wedge-shaped consolidation of the anteriorly positioned right upper lobe. The major fissure is displaced anteriorly. There is extensive filling of the distal bronchiectatic segmental and subsegmental airways of the RUL. Final diagnosis was a central RUL proximal squamous cell carcinoma.

Necrotic Squamous Cell Carcinoma

52 year old male with known squamous cell carcinoma of the lung
CT scan in the axial projection shows a large low density mass in the right upper lobe with invasion into the neural foramen of the abutting vertebral body. Antero-laterally, the mass is low density and postero-medially it is slightly higher density. PET CT shows a rind of intense activity surround the necrotic center and invading the vertebra. Findings are consistent with a squamous cell carcinoma

55-year-old male presenting with dyspnea
Coronal CT at the level of the trachea and mainstem bronchi, shows atelectasis of the RUL caused by a central obstructing lesion in the right upper lobe bronchus (b, white arrowhead) resulting in atelectasis of the RUL characterized by a wedge-shaped consolidation of the right upper lobe with superiorly displaced major fissure (a, pink arrowhead). There is extensive filling of the distal bronchiectatic segmental and subsegmental airways of the RUL (b, yellow arrowheads). Final diagnosis was a central RUL proximal squamous cell carcinoma.

Squamous Cell Carcinoma Masquerading as ABPA

56-year-old male presents with chronic cough dyspnea and weight loss. CT scan in coronal projection shows an appearance reminiscent of finger in glove in the right lower lobe. There s segmental and subsegmental thickening of the airways in the upper lobes, and paraseptal emphysema. Micronodules in the upper lobes suggest smoker?s bronchiolitis. The subcarinal esophageal mass was diagnosed as a leiomyoma, Pathology of the right lower process was a squamous cell carcinoma

56-year-old male presents with chronic cough dyspnea and weight loss. CT scan in axial projection shows an appearance reminiscent of finger in glove in the right lower lobe. There s a para-fissural soft tissue mass that seems ?soft? since it does not displace nor deform the fissure.. Pathology of the right lower process was a squamous cell carcinoma

This is a case of poorly differentiated non small cell carcinoma presenting as a large necrotic mass, with a percutaneous biopsy (2) treated with radiation therapy (3), with associated small nodes (4) overlaid in green, (5) with a response as seen by shrinkage of the tumor 4 months later (6) as well shrinkage of the nodes (7, 8).
