Unusual Locations of Pancreatic Pseudocysts in Lumbar Triangle, Psoas Muscle and Intercostal Space, and Obturator Externus.

Pancreatic pseudocyst develops as a complication of both acute and chronic pancreatitis. Although the common location of pseudocyst is lesser sac, extension of pseudocyst can occur into mesentery, retroperitoneum, inguinal region, scrotum, liver, spleen, mediastinum, pleura, and lung. Extension of pseudocyst into psoas muscle and lumbar triangle is extremely rare.

Necrotizing Fasciitis of Thoracic and Abdominal Wall with Emphysematous Pyelonephritis and Retroperitoneal Abscess.

Emphysematous pyelonephritis is a life-threatening severe form of pyelonephritis usually occurring in patients with diabetes mellitus with or without obstructive uropathies in whom there is necrotizing infection leading to the gas production of an unclear mechanism involving the renal parenchyma and the collecting system. Necrotizing fasciitis is characterized by progressive necrosis of fat and fascia due to deep-seated infection of subcutaneous tissue. It has a fulminant course with considerable mortality.

Plexiform Neurofibroma in the Axilla with Intraosseous Neurofibroma in the Humerus in Neurofibromatosis 5.

Segmental neurofibromatosis type 5 (NF5) is a rare form of NF, in which the cutaneous and/or neural changes are confined to one region of the body. It is often underdiagnosed or undetected due to the absence of symptoms. Inheritance of NF is different from other types of NF.

The Herlyn-Werner-Wunderlich Syndrome - A Case Report with Radiological Review.

Background: HWW syndrome is a very rare congenital anomaly of urogenital tract involving Mullerian ducts and mesonephric ducts. It is characterised by a triad of symptoms - uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. It can be classified based on a completely or incompletely obstructed hemivagina.

Pulmonary Alveolar Microlithiasis - Clinico-Radiological dissociation - A case report with Radiological review.

Pulmonary alveolar microlithiasis (PAM) is a rare chronic lung disease characterized by deposition of intra alveolar calcium and phosphate in bilateral lung parenchyma with predominance in lower and mid zones. Etiology and pathogenesis is not fully understood. However, mutation in SLC34A2 gene that encodes a sodium phosphate co-transporter in alveolar type-II cells resulting in formation and accumulation of microliths rich in calcium phosphate due to impaired clearance is considered the cause of disease.
