Introduction: Intercostal hemangioma is an extremely rare disease. It is difficult to distinguish intercostal hemangioma from other chest wall tumors. The difficulty in preoperative diagnosis may result in incomplete surgical resection and hence a high rate of recurrence.

Case Presentation: A 14-year-old boy who presented with asymptomatic right lateral chest wall mass with no history of trauma. Different radiological modalities were employed for diagnosis including computed tomography (CT) showed a soft tissue mass 6.5×4×5.6cm in size abutting 5th and 6th ribs. Magnetic resonance imaging (MRI) revealed iso-intense signal in T1 and hyperintense signal in T2, that is higher than that of adjacent muscles in the inferolateral right chest wall which was compatible with intercostal hemangioma. The patient underwent surgery for excision of the mass. Through right posterolateral thoracotomy, there was a well-demarcated mass abutting 5th, and 6th ribs filling the right 5th interspaces. Histopathological examination confirmed the diagnosis of intercostal hemangioma.

Discussion: Chest wall hemangiomas are uncommon and mostly arise outside the rib cage. Hemangiomas rarely occur in the intercostal space, and most of these originate from intercostal muscles (Agarwal et al., 2006). Watson and McCarthy postulated two theories for the etiology of hemangiomas. The more widely supported theory claims that hemangiomas are of congenital origin. The other theory proposes a traumatic origin of hemangiomas.

Conclusion: Complete surgical resection should not be compromised by the resultant chest wall defect to prevent recurrence.

Introduction: Solitary plasmacytomas are tumors characterized by a local increase of malignant plasma cells in soft tissue or bone and may occur anywhere without evidence of systemic disease. The aim was to focus on the main surgical techniques and outcomes for this rare chest wall tumor.

Methods: Patients with solitary plasmacytoma involving a rib, who were operated for diagnostic or treatment purposes between 2018 and 2023 were retrospectively reviewed.

Effects of osteosynthesis of the bony thorax in the context of polytrauma compared to conservative treatment: a systematic review.

Eur J Trauma Emerg Surg

January 2025

Department of Intensive Care Medicine and Intermediate Care Medical Faculty, RWTH Aachen University, Pauwelsstr. 30, D-52074, Aachen, Germany.

Purpose: Osteosynthesis seems to have effects regarding clinical outcomes in trauma patients. However, current knowledge on chest wall osteosynthesis in polytrauma patients is insufficient, leaving its potential unanswered. Therefore, the objective of this systematic review is to assess the safety and effects of chest wall osteosynthesis compared to conservative treatment on clinical outcomes in adult polytrauma patients.

We present a case report of a 42-year-old female with post-West Nile virus meningoencephalitis who exhibited unique, long-latency diaphragm potentials evoked by transcranial and cervical magnetic stimulation after exposure to acute intermittent hypoxia (AIH). The subject was recruited for a study investigating AIH effects on respiratory motor function in healthy individuals. She had contracted West Nile virus infection 5 years before assessment that resulted in hospitalization and persistent allodynia but was not reported to the research team.

Intervertebral thoracic disk herniation (TDH) is a rare occurrence and presents with a wide variety of symptoms. Errors in diagnosis are thought to be frequent due to the variable clinical presentations. We herein present two unusual cases of TDH presenting with abdominal pseudohernias, abdominal pain, and hypoesthesia along the T11-T12 dermatomes due to TDH at the same level.

Introduction: Breathing-synchronized hypoglossal-nerve stimulation is a treatment option for suitable patients with severe obstructive-sleep-apnoea. The classical implantation technique requires three incisions: submental to place the stimulating-electrode on terminal branches of the hypoglossal-nerve, sub-clavicular to place the impulse generator, and on the lateral chest-wall to place a breathing-sensor lead. A two-incision-technique has been propagated and widely adopted whereby the respiratory-sensing-lead is placed deeper to the IPG-pocket.
